The embodiment of the application provides a table creating method and device, electronic equipment and a computer readable storage medium. The form creating apparatus may be integrated in an electronic device, and the electronic device may be a server or a terminal.

The execution main body of the table creating method in the embodiment of the present application may be the table creating apparatus provided in the embodiment of the present application, or different types of electronic devices such as a server device, a physical host, or a User Equipment (UE) integrated with the table creating apparatus, where the table creating apparatus may be implemented in a hardware or software manner, and the UE may specifically be a terminal device such as a smart phone, a tablet computer, a notebook computer, a palm computer, a desktop computer, or a Personal Digital Assistant (PDA).

The electronic device may adopt a working mode of independent operation, or may also adopt a working mode of a device cluster.

First, the related background art of the present application is introduced:

an electronic whiteboard, also known as an electronic interactive whiteboard, is a new high-tech electronic teaching system. It is integrated by hardware electronic induction white board and software white board operation system. The electronic whiteboard integrates multiple functions of a traditional blackboard, a computer, a projector and the like, and is very convenient to use. In the process of displaying, a table is often required to be inserted to summarize data, a common table generation method is to determine 4 vertexes of each cell in the table to generate the table, however, in this method, positions of a large number of vertexes need to be calculated under the condition that rows and columns of the table are large and the number of cells is large, so that the calculation amount is large, the speed of generating the table is slow, the speed of displaying the table cannot keep up with that of a user, and neither a presenter nor a presenter is friendly.

Referring to fig. 1, fig. 1 is a schematic view of a scenario of a table creation system provided in an embodiment of the present application. The form creating system may include an electronic device 100, and a form creating apparatus is integrated in the electronic device 100.

In addition, as shown in fig. 1, the table creation system may further include a memory 200 for storing data, such as storing text data.

It should be noted that the scenario diagram of the table creation system shown in fig. 1 is only an example, and the table creation system and the scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation to the technical solution provided in the embodiment of the present application.

In the following, a table creation method provided in an embodiment of the present application is described, in the embodiment of the present application, an electronic device is used as an execution subject, and for simplicity and convenience of description, the execution subject will be omitted in subsequent embodiments of the method.

Referring to fig. 2, fig. 2 is a flowchart illustrating a table creating method according to an embodiment of the present application. It should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein. The table creating method may specifically include the following steps 201 to 203, where:

201. and responding to a table creating instruction, and determining the corner position according to the table attribute associated with the table creating instruction.

The user can send out the table creating instruction in various modes according to the terminal for creating the table. For example, a user may send a table creation instruction through an external device such as a mouse and a keyboard, which is not limited in this embodiment of the present application. In the table creating instruction, attributes of the table are associated, and a user can associate different table attributes for the table creating instruction when the table creating instruction is issued. Specifically, the user can click the function key of "create table" in the screen by operating the mouse, and then input the number of rows and columns of the table and the size of the cells in the table by the keyboard. Alternatively, a table creation instruction associated with a table attribute may also be issued by the following method: the method comprises the steps that a user changes the position of a cursor in a screen by moving a mouse, when the position of the cursor in the screen is detected to be matched with a function key of 'table creation', an auxiliary window used for table creation is displayed in the screen, a visual graph of a table is displayed in the auxiliary window, the user selects at least one part of the visual graph in a frame selection mode, a click mode and the like to send a table creation instruction, the number of rows and columns related to the table creation instruction is the number of rows and columns of a part of the table contained in the part, and the size of a cell is the default size of a system or the size set by the user in advance. Referring to fig. 3, a function key a, an auxiliary window B and a cursor C are shown in fig. 3, and cells B1-B6 in the auxiliary window are at least a part of visual graphics selected by a user through a frame selection, a click selection and the like, and it can be understood that the number of table rows and columns in the table attribute is 2 rows and 3 columns at this time.

In addition to the number of rows and columns of the table and the size of the cells, visual attributes for changing the visual effect of the table may be included in the table attributes. When the user issues the form creation instruction, the user may simultaneously select visual attributes such as the thickness of the form line and the color of the form line, for example, the number of pounds of the form line may be set to 4 pounds, and the color of the form line may be set to red.

In some embodiments, the user-entered attribute in the table attribute may include only one of the above-mentioned row and column numbers, cell sizes, visual attributes, and the like, and in this case, the other attributes in the table attribute except the user-entered attribute adopt preset default values. For example, if the user-entered attribute in the table attribute includes only the number of rows and columns, other attributes such as the size of the cell, the color of the table line, and the thickness of the table line may be defaults.

The corner position may be a position of four corners of a target form corresponding to the form creating instruction in a form display interface, or a position of four corners of the target form in a terminal display screen, where the form display interface may be a canvas display interface of an electronic whiteboard. For example, a two-dimensional interface coordinate system may be established in the tabular display interface, and coordinates of corner points in the interface coordinate system may be determined to obtain corner point positions. Or, a two-dimensional interface coordinate system may be established in the terminal display screen, and coordinates of corner points in the interface coordinate system are determined to obtain the corner point positions. Hereinafter, if the size and the position appear, they are considered as the size and the position in the interface coordinate system of the terminal display screen, for convenience of understanding. Continuing with fig. 3 as an example, fig. 3 includes a table display interface D and a terminal display screen E, assuming that the upper left corner of E in fig. 3 is taken as the origin of the coordinate system, the wide direction of E is taken as the positive direction of the X axis, and the high direction of E is taken as the positive direction of the Y axis to establish the interface coordinate system, if the coordinates of the four corner points D1, D2, D3, D4 of the target table are (1,0), (7,4), (1,4), respectively, the corner points are (1,0), (7,4), (1, 4). In some embodiments, the corner position may also refer to the position of 2 diagonal corners of the target table in the terminal display screen, and taking fig. 3 as an example, the corner position may also be (1,0), (7,4), or (7,0), (1, 4). In addition, the calculated positions may also be shifted, for example, the positions of 4 corner points may all be shifted left or up by the same size to obtain the corner point positions.

Specifically, any point in the table display interface may be used as one of the corner points of the target table, and then the position of the corner point is calculated according to the table attribute. Continuing with the example of fig. 3, d1, d2, d3, d4 in fig. 3 are the four corner points of the target table. When determining the corner point positions, an interface coordinate system may be established first, the establishment method is the same as above, then the coordinates of any point in d1/d2/d3/d4 are preset, here, taking d1 as an example, the coordinates of d1 in the interface coordinate system are set to (1,0), then the distances between the corner points are calculated according to the number of rows and columns in the table attributes and the sizes of the cells, assuming that the number of rows and columns of the target table is 2 rows and 3 columns, and the width and height of each cell in the interface coordinate system are 2 and 2, then the distances between d1 and d2, between d3 and d4 in the interface coordinate system are 6, and the distances between d1 and d4, between d2 and d3 in the interface coordinate system are 4, and further the coordinates of d2, d3, and d4 in the interface coordinate system are (6,0), (6,4), (0,4), respectively. If the corner positions are only the positions of 2 diagonal corners of the target table, that is, the corner positions in fig. 3 only include the positions of d1 and d3 in the interface coordinate system, or only include the positions of d2 and d4 in the interface coordinate system, the calculation process is also the same as above, and is not described herein again.

202. And determining the positions of the boundary grid points according to the corner positions and the table attributes.

The boundary grid point positions refer to positions of cell points on the table boundary line of the target table, i.e., boundary grid points. For example, a two-dimensional interface coordinate system may be established in the table display interface, and coordinates of boundary grid points in the interface coordinate system may be determined to obtain positions of the boundary grid points. Referring to fig. 4, fig. 4 also includes boundary grid points e1-e6 on the basis of fig. 3, and if the coordinates of e1-e6 on the interface coordinate system in fig. 4 are (3,0), (5,0), (7,2), (5,4), (5,2), and (1,2), the boundary grid points are (3,0), (5,0), (7,2), (5,4), (5,2), and (1, 2).

Specifically, the boundary grid point positions may be determined according to at least one of a cell size and a number of rows and columns of the table in the table attribute. Taking the number of table rows and columns as an example, after determining the corner positions as (1,0), (7,4) and (1,4), assuming that the number of table rows and columns is 2 rows and 3 columns, the height of the table can be determined according to (1,0) and (1,4), and the height is divided by the number of rows to obtain the height of each row, and then the coordinates of the boundary grid point corresponding to each row are obtained by calculation according to the height of each row and the corner position, and according to (1,0) and (1,4), the height of the table can be obtained as 4 in the interface coordinate system, and the height of each row can be obtained as 2 by dividing by the number of rows 2, so that the position of the boundary e6 can be obtained by calculation as (1,2), and similarly, the positions of e1-e5 in fig. 4 can be obtained by calculation, and further the position of the boundary grid point can be obtained.

203. And performing table drawing according to the corner point position and the boundary grid point position to obtain a target table.

And connecting the corner points corresponding to the corner point positions in sequence to obtain the table boundary line of the target table. And matching and connecting every two boundary grid points corresponding to the positions of the boundary grid points, so that each cell can be divided in the table boundary. Therefore, the target grid can be drawn according to the positions of the corner points and the positions of the boundary grid points. Specifically, referring to fig. 4, the principle of matching between boundary grid points is to match between boundary grid points with the maximum X value and the minimum X value in the boundary coordinate system according to the Y value, where the Y values are the same as one group, to achieve pairwise matching, and match between boundary grid points with the non-maximum X value and the non-minimum X value in the boundary coordinate system according to the X value, where the X values are the same as one group, to achieve pairwise matching, so in fig. 4, e1 is grouped with e5, e2 is grouped with e4, and e3 is grouped with e 6. And connecting the boundary grid points in each group through straight lines to obtain the cell dividing lines of each cell in the table. And refreshing the table display interface according to the cell boundary line and the table boundary line to generate the target grid.

In some embodiments, the corner position may be determined according to the form attribute and the size of the form display interface, and the target form drawn according to the corner position is located in the center of the form display interface. Referring to fig. 5, at this time, determining the corner position according to the table attribute associated with the table creating instruction in response to the table creating instruction includes:

301. and responding to a table creating instruction, and acquiring the table attribute associated with the table creating instruction.

The meaning of the table attribute can be referred to the above explanation, and is not repeated.

302. And calculating to obtain the target table size according to the table row and column number and the cell size in the table attribute.

The target table size includes a width and a height of the target table. Specifically, the target table size can be calculated by equations (1) and (2):

tableWidth ═ cellWidth ═ column formula (1)

tableHeight ═ cellHeight ═ row formula (2)

Wherein, tableWidth is the width of the target table, cellWidth is the cell width in the cell size, column is the number of table columns in the row and column number of the table, tableHeight is the height of the target table, cellWidth is the height of the cell in the cell size, and row is the number of table rows in the row and column number of the table.

303. And determining the position of the corner point according to the target table size and the preset interface size of the table display interface.

Specifically, the corner position can be calculated by equation (3) -equation (10):

left ═ width (width-tableWidth)/2 formula (3)

right ═ width + tableWidth)/2 formula (4)

top ═ height-tableHeight)/2 formula (5)

bottom ═ height + tableHeight)/2 formula (6)

P1(x1, y1), x1 left, y1 top (7)

P2(x2, y2), x2 right, y2 top formula (8)

P3(x3, y3), x3 ═ left, y3 ═ bottom formula (9)

P4(x4, y4), x4 right, y4 bottom formula (10)

Wherein, width is the interface width in the preset interface size, height is the interface height in the preset interface size, P1(x1, y1), P2(x2, y2), P3(x3, y3), P4(x4, y4) are the positions of 4 corner points respectively, that is, the corner point positions include P1(x1, y1), P2(x2, y2), P3(x3, y3), and P4(x4, y 4).

In addition, whether the target form size exceeds the maximum size which can be displayed by the interface or not can be judged according to the preset interface size, and if the target form size exceeds the maximum size which can be displayed by the interface, the target form size is adjusted. At this time, determining the corner position according to the target form size and the preset interface size of the form display interface includes:

(1) and comparing the target table size with a preset interface size of a table display interface.

The preset interface size may refer to a size of the form display interface on a display screen of the terminal, for example, when the form display interface is a canvas of an electronic whiteboard, the preset interface size may be a size of the canvas, and a user may adjust the size of the canvas in advance through function keys such as "full screen display", "window display", and the like. It should be noted that, if the preset interface size is a size of the table display interface on the terminal display screen, the target table size needs to be in the same size dimension as the preset interface size, that is, the target table size also refers to a size of the target table on the terminal display screen, and if the target table size is the size of the target table on the table display interface, size conversion may be performed on the target table, and a specific conversion method is not described in detail.

(2) And if the target width in the target table size is larger than the interface width in the preset interface size and/or the target height in the target table size is larger than the interface height in the preset interface size, calculating to obtain the adjusted cell size according to the preset interface size and the table row and column number.

If the target width in the target form size is greater than the interface width in the preset interface size and/or the target height in the target form size is greater than the interface height in the preset interface size, it indicates that the target form cannot be completely displayed on the form display interface, and the user needs to view the entire form by scrolling the mouse, which is very inconvenient. Therefore, the adjusted cell size can be obtained through calculation according to the preset interface size and the row number and the column number of the table, and the table generated according to the adjusted cell size and the row number and the column number of the table can be completely displayed in the table display interface.

Specifically, the adjusted cell size may be the largest cell size in the table that can be completely displayed in the table display interface after the number of rows and columns of the table is determined. If the target width in the target table size is greater than the interface width in the preset interface size, the interface width in the preset interface size may be taken as the width of the target table. If the target height in the target table size is greater than the interface height in the preset interface size, the interface height in the preset interface size may be taken as the height of the target table.

Assuming that the number of rows and columns of the table is 2, 3, the target width in the target table size is 6, the target height is 4, the interface width in the preset interface size is 3, and the interface height is 10, since the target width is greater than the interface width, the interface width can be taken as the width of the target table, and the cell width of each cell in the target table is calculated, in this example, the width of each cell is 1, since the target height is less than the interface height, the target height is retained, that is, the height of the target table is still 4, and the cell height of each cell is 2. The adjusted cell size is therefore: the cell width is 1 and the cell height is 2. The same process can be performed for the case where the target width is smaller than the interface width, the target height is greater than the interface height, and the case where the target viewing width is greater than the interface width and the target height is greater than the interface height, which are not described herein again.

(3) And determining the adjusted table size according to the adjusted cell size and the table row and column number.

The method for calculating the adjusted table size is the same as that in step 302, and is not described in detail.

(4) And calculating to obtain the position of the angle point according to the adjusted table size and the preset interface size.

The manner of calculating the corner position may refer to equations (3) to (10), which is not described in detail.

In some embodiments, the generated target table may include a header cell with a more obvious visual effect to improve the experience of the user. Referring to fig. 6, at this time, performing table drawing according to the corner position and the boundary grid point position to obtain a target table, including:

401. and determining the positions of the table boundary lines and the positions of the cell division lines according to the angular point positions and the positions of the boundary grid points respectively.

The table boundary line position includes the position of each pixel point constituting the 4 table boundary lines, and the cell division line position includes the position of each pixel point constituting the cell division line. Specifically, the boundary line position and the cell division line position may be determined in the following manner. Taking the position of the boundary line as an example, referring to fig. 3, if the coordinates of the four corner points d1, d2, d3, d4 of the target table are (1,0), (7,4), (1,4), respectively, the positions of all the pixels with the Y value of 0 and the X value between 1 and 7 are taken as the positions of the boundary lines of one of the tables, and the same applies to the positions of the boundary lines of the other 3 tables.

402. And generating a table to be filled according to the position of the table boundary line and the position of the cell dividing line.

The table to be filled is generated according to the position of the table boundary line and the position of the cell dividing line, and the cells are not filled with colors. Specifically, the table to be filled may be generated by filling colors in the pixels corresponding to the positions of the table boundary lines and the positions of the cell division lines to generate the table boundary lines and the cell division lines in the table to be filled, and then refreshing the table display interface. It should be noted that the manner of generating the table to be filled is substantially the same as the manner of generating the target table in step 203, and the essence of the connection line in step 203 is to first determine the position of each line, and then fill the color into the pixels corresponding to each line to generate each line.

403. And carrying out color filling processing on the table head cells in the table to be filled to obtain a target table.

The definition of the head cell may vary according to the user's setting, for example the head cell may be the topmost cell of the columns. The purpose of filling the table head cells with colors is to enhance the visual effect and facilitate users to know the meaning of data in the target table.

In some embodiments, the size of the target table may be adjusted to accommodate different scenarios after the target table is generated. Referring to fig. 7, at this time, after performing table drawing according to the corner position and the boundary grid point position to obtain a target table, the method further includes:

501. determining a table intrinsic property of the table properties in response to an intrinsic property definition instruction.

The inherent attribute definition instruction refers to an instruction issued by a user for locking the attribute values of one or more attributes in the table attribute. For example, the user may issue an inherent attribute definition instruction to lock the values of the rows and columns of the table, so that when the subsequent user adjusts the size of the target table, no matter how the adjustment is made, the number of rows and columns of the adjusted table will not change. Alternatively, the user may also lock the value of the cell size by issuing the inherent attribute definition instruction, and the embodiment of the present application does not limit the locked attribute.

The user may issue the intrinsic property definition instruction in a variety of ways. Specifically, the user may issue the intrinsic property definition instruction by means of a mouse click. For example, the user may click a "table setup" function key by operating a mouse, and then select "column and row number lock" from the skipped child window to issue an inherent attribute definition command.

The table inherent attribute refers to an attribute locked out among table attributes. If the user locks the value of the table row and column number, the inherent attribute of the table refers to the table row and column number. If the user locks the value of the cell size, the table intrinsic property refers to the cell size.

502. And responding to a table adjusting instruction, and generating an adjusted table according to the target adjusting size and the inherent attributes of the table associated with the table adjusting instruction.

The table adjustment instruction refers to an instruction issued by the user to adjust the size of the target table. The user may issue the table adjustment instruction in a variety of ways. Specifically, the user may select a table boundary line of the target table or a corner point of the target table, and issue a table adjustment instruction in a dragging manner. Alternatively, the user may directly input the adjusted target size to issue a table adjustment instruction.

The target resizing size is an adjusted target size, and if the user inputs an adjusted target width of 8 and an adjusted target height of 8 when issuing a table adjustment instruction, the target resizing size includes a width of 8 and a height of 8.

The adjusted table can be generated by the same method as above according to the target resizing and the table inherent properties. For example, the corner position of the adjusted form may be determined according to the target adjusted size and the preset interface size, then the boundary grid point position of the adjusted form may be determined according to the corner position of the adjusted form and the inherent attributes of the form, and finally, the form may be drawn according to the corner position of the adjusted form and the boundary grid point position of the adjusted form, so as to obtain the adjusted form.

For the conventional table, when the size of the cell in the conventional table is adjusted, a user needs to select the boundary line of the cell, i.e. the cell dividing line, and then change the size of the cell by dragging and the like. The embodiment of the application provides a more convenient size adjustment mode, and is more convenient for a handwritten electronic whiteboard. Referring to fig. 8, at this time, after performing table drawing according to the corner position and the boundary grid point position to obtain a target table, the method further includes:

601. and responding to a cell selection instruction, and selecting a target cell pointed by the cell selection instruction in the target table.

The cell selection instruction is an instruction for selecting a target cell. The user may issue the cell selection instruction in a variety of ways. For example, a user may issue a cell selection instruction on an electronic whiteboard by means of a finger touch screen, and after the position where the user touches the touch screen is matched with the position of each cell in the target table, a target cell may be determined. Or, the user may also send a cell selection instruction by clicking a left mouse button, and after matching the position of the cursor when clicked with the positions of the cells in the target table, the target cell may be determined.

602. And responding to a dragging instruction, and carrying out size adjustment on the target cell and the cells in the same column and/or the same row corresponding to the target cell according to a dragging parameter in the dragging instruction.

The user can send the dragging instruction by keeping the state of the finger touch screen and then moving the finger, or can send the dragging instruction by keeping the state of the left mouse button and then moving the mouse, which is not limited in the embodiment of the application.

The dragging parameters comprise parameters such as dragging direction and dragging distance, the dragging direction is used for judging whether the size of the cell is increased or decreased, and the dragging distance is used for representing the adjustment degree. The dragging direction may include only one direction, or may include a plurality of directions at the same time. For example, when the user issues a drag command by holding the left button of the mouse in a pressed state and then moving the mouse, the direction of the drag command includes only one direction, and whether to increase or decrease the cell size can be determined according to the direction. In the case of a finger touch screen, a user may move a finger to the outside of a target cell using a plurality of fingers at the same time, and at this time, although the dragging direction includes a plurality of directions, it may be determined whether to increase the size of the cell or decrease the size of the cell by determining a relative relationship between each direction and the target cell, and if a majority of the directions point to the outside of the target cell, it may be determined that the size of the cell should be increased, and if a majority of the directions point to the inside of the target cell, it may be determined that the size of the cell should be decreased.

It can be seen that through the method of steps 601-602, the user does not need to mark lines on the cells with low selected point size, but only needs to select the cells, which is particularly friendly in the case of touch screen operation.

In some embodiments, the user may also send form creation instructions by handwriting input, voice input, pictures, and the like. Referring to fig. 9, at this time, before determining the corner position according to the table attribute associated with the table creating instruction in response to the table creating instruction, the method further includes:

701. receiving user input data, wherein the user input data is at least one of handwriting data, voice data and picture data.

Handwriting data refers to data input by a user through handwriting input. Illustratively, a user may enter input via a stylus or may handwriting with a finger on an electronic whiteboard supporting handwriting to enter user input data. For example, a user may write "create a 2-row and 3-column table" on an electronic whiteboard that supports handwriting with a finger, or may directly draw a 2-row and 3-column table, where the user inputs data, i.e., data that includes the handwriting.

The voice data refers to data input by a user through voice input. Illustratively, the user may make input through a voice capture device such as a microphone. For example, a user may speak via a microphone: "create a table with 2 rows and 3 columns" and the user inputs data, i.e. data containing the speech input.

The picture data refers to data including image information. For example, a user may place a picture under an image capture device, such as a camera, to input picture data in the picture. For example, a user may place a picture taken with a table of 2 rows and 3 columns under the camera and the user enters data, i.e., data comprising the picture.

702. And identifying the user input data to obtain a table creation instruction.

Different recognition processes can be performed on the user input data according to the type of the user input data. Illustratively, the user input data is handwriting data, and when the user input data is written text information, the user input data may be subjected to an OCR (Optical Character Recognition) Recognition process to acquire information related to table creation in the handwriting data. For example, after writing "create a table with 2 rows and 3 columns" on the electronic whiteboard, the user may perform OCR recognition processing on the handwriting data to obtain information "with 2 rows and 3 columns" therein, and generate a table creation instruction according to the information. For another example, when the user input data is voice data, it may be processed by a voice recognition model such as fsmn (fed forward Sequential Memory networks), cfsmn (compact fed forward Sequential Memory networks), etc. to obtain information of "2 rows and 3 columns" therein, and generate a table creation instruction according to the information.
