Description

The present invention relates to a method for efficiently creating ruled lines in a table displayed on the screen of an information processing device such as a computer or a word processor.

<Prior Art> Conventionally, when editing a complicated table that includes characters and figures and is separated by vertical and horizontal ruled lines that do not have a grid pattern, for example, a word processor uses a ruled line editing function for each frame. The entire table is constructed using the character and figure editing functions for the letters and figures inside.

<Problems to be solved by the invention> However, when creating a ruled line in a table by the above-mentioned conventional editing method, after specifying the ruled line creation mode and entering this mode, the position where the ruled line is created and the vertical and horizontal directions The process of designating the ruled line by the length of one character on a different screen with the cursor or the mouse is repeated. Therefore, when attempting to create a long ruled line that continues over several blocks or a ruled line that bends in a complicated manner, there are drawbacks that it takes a long time to create and the operation of the cursor and the like becomes complicated.

Therefore, an object of the present invention is to use a rectangular information memory that stores, for each block, the coordinates, dimensions, and mutual geometrical relation of each block, in addition to the character and graphic data in each block separated by ruled lines. Accordingly, it is an object of the present invention to provide a ruled line creation method for a table that can easily and efficiently create a specified ruled line within the entire range of a table or the range of a selected block group.

<Means for Solving the Problems> In order to achieve the above object, the ruled line creation method of the table of the present invention refers to and changes the contents of the memory according to the program by the CPU based on the information input from the input unit. While generating display data while displaying the display data as a table including characters and graphics on the display unit,
A content information memory that stores the character and graphic data of each block delimited by the vertical and horizontal ruled lines in the above table for each block, the data type of each block, the starting point coordinates, the width, the height, and the rectangle of the adjacent block. Pointer to information memory,
A tune pointer to the rectangular information memory of a new block, a rectangular information memory that stores a data pointer to the above content information memory for each block, and x, y from the origin of the above table
When the coordinate value is gradually increased, a block index memory that sequentially stores a pointer to the rectangular information memory of the first block that appears next, and a straight line vertically or horizontally within the entire range of the above table or the range of the selected block group. A coordinate input means for inserting an auxiliary line to be formed, moving it horizontally or vertically within the range and stopping it at a desired position, and a block divided into two by the auxiliary line positioned by the coordinate input means. Obtain a new rectangular information memory and a new area for the content information memory in each obtained block, and set the starting point coordinates, width, and height data and content information in the rectangle information memory of the original block and the new block. The character and graphic data in the memory is updated or newly generated based on the auxiliary line position data and stored, and a ruled line is displayed at the auxiliary line position. The lock adding means and the original block are connected by the first pointer chain, the new blocks are connected by the second pointer chain, respectively, and the original block, the new block and the newly adjacent block are paired. The pointer is set in the rectangular information memory of these blocks to connect the new block to the new area of the content information memory by connecting with the pointer, while the starting point coordinates, width and height in the updated or newly stored rectangular information memory are set. It is characterized in that it is provided with a pointer setting means for setting a new pointer in the block index memory on the basis of the length data, and creates a ruled line at the auxiliary line position determined by the coordinate input means.

<Action> Characters of each block in the table displayed on the screen of the display,
The graphic data is stored in the content information memory, and the starting point coordinates, width, and height of each block and the data pointer to the content information memory are stored in the rectangular information memory for each block.

Now, by the coordinate input means, an auxiliary line forming a straight line in the vertical or horizontal direction is inserted into the entire range of the above table or the range of the selected block group, and the auxiliary line is moved in the horizontal or vertical direction within the range, and the desired position is obtained. Then, the block addition means obtains a block divided into two by the stopped auxiliary line, and secures a new area of a new rectangular information memory and a new content information memory in each obtained block, and the original block And the starting point coordinates in the rectangle information memory of the new block,
The width and height data and the character and graphic data in the content information memory are updated or newly generated based on the auxiliary line position data and stored, and a ruled line is displayed at the auxiliary line position.

Next, the pointer setting means sets the original blocks to the first
In the pointer chain, the new blocks are connected to each other by the second pointer chain, and the original block and the new block and the newly adjacent blocks are connected by the pointer, and the new block is added to the content information memory. A pointer is set in the rectangular information memory of these blocks in order to connect to these areas, while a new index is added to the block index memory based on the updated or newly stored data of the starting point coordinates, width, and height in the rectangular information memory. Set the pointer. In this way, a ruled line is quickly created at the auxiliary line position determined by the coordinate input means, and the character or figure that is the content of the original block is also divided into two by the ruled line.

<Examples> Hereinafter, the present invention will be described in detail with reference to illustrated examples.

FIG. 1 is a block diagram showing an embodiment of a word processor adopting the ruled line forming method for a table of the present invention. According to the table block generation program 6a of the program memory 6 by the CPU 1 based on the information input from the key input device 2, this word processor refers to the table block information memory 7a of the data memory 7 and changes the table block information. The generated data is displayed as a table composed of a plurality of blocks separated by vertical and horizontal ruled lines on the display device 5 through the display memory 4, while the characters in the program memory 6 and the character and graphic data are generated according to the graphic generation program 6b. Is generated and stored in the content information memory 7b of the data memory 7, and is displayed in the plurality of blocks on the screen of the display device 5 via the display memory 4.
In addition, in the word processor, an auxiliary line that is a straight line in the vertical or horizontal direction is inserted into the entire range of the table displayed on the screen of the display device 5 or the range of the selected block group,
A coordinate input device 3, such as a mouse, is provided for moving this in a horizontal or vertical direction within the range and stopping it at a desired position.

FIG. 3 shows the details of the data memory 7. The table block information memory 7a is displayed on the screen as shown in FIG. 2, for example, a to e (b ', c', e'are the first The rectangular information memories 11a to 11e (partly not shown) for storing the structural information of each block (not shown) and the arrangement order of each block with respect to the origin (x1, y1) in the table of FIG. The block index memory 12 that stores as a sequence of pointers to the rectangular information memory, the coordinates (xi) of the ruled line to be created that is positioned by the coordinate input device 3 and the rectangular information memories of the blocks on both sides sandwiching the coordinate Pointer (e,
e ') (see FIG. 4) is stored in the block selection information memory 13. On the other hand, the content information memory 7b stores the character and graphic data as the content of each block for each block.

In each of the above rectangular information memories 11, the data type (character or graphic) of the corresponding block in order from the top, the starting point coordinates (x, y coordinates of the upper left corner), the width, the height, and the rectangle of the blocks connected to the bottom and the right. A pointer to the information memory, a chain pointer described later, and a data pointer to the content information memory 7b are stored. The nil in the rectangular information memory 11 indicates that there is no pointer. In addition, the index memory 12
Is divided into an x-part and a y-part, and the pointers to the rectangular information memories of the blocks that appear first when the x, y coordinate values are gradually increased from the origin (x1, y1) in the table of FIG. Sequentially stored in x part and y part. The block selection information memory 13 in FIG. 3 contains data when the entire table without ruled lines is selected as one block. In addition, the rectangular information memories 11b, 11c, 11e shown in the figure
Since the data types of all are text (TEXT), katakana character data is stored in the corresponding area of the content information memory 7b as shown in the figure.
In the case of C), graphic data is stored.

On the other hand, the CPU 1 of the word processor serves both as a block adding means and a pointer setting means. That is, the CPU 1 as the block adding means forms the auxiliary line by the coordinate input device 3 as shown by the broken line in FIG. 2 (coordinates xi), and the auxiliary line is shown in the lower part of the block selection information memory 13 in FIG. As shown in the example, when the pointers to the blocks e and e'divided by the auxiliary line are entered, the blocks b and c divided by the auxiliary line are obtained, and the obtained blocks b'and c ' , e ', new rectangular information memory 11b', 11c ', 11e' and content information memory 7b
Of the original block b, c, e and the new blocks b ', c', e'of the starting point coordinates, width, and height data in the rectangular information memory and the content information memory 7b. Character,
Graphic data is updated or newly generated and stored as shown in FIG. 4 based on the auxiliary line position data, and a solid ruled line is displayed at the auxiliary line position.

As shown in FIG. 4, the CPU 1 as the pointer setting means uses the first pointer chain P of the original blocks b, c, e.
_{At 1} , the new blocks b ′, c ′, e ′ are connected to each other by the second pointer chain P ₂ , and the original block and the new blocks b, b ′; c, c ′; e, e ′ to pointer P ₃
In newly respectively connecting the adjacent blocks in the pointer P _4, a new block b ', c', the pointer to the rectangle information memory of these blocks to connect the pointer P ₅ the e 'to a new area of the content information memory 7b To set. Also, the updated or newly stored rectangular information memories 11a to 11e, 11
A new pointer P ₆ is set in the block index memory 12 based on the starting point coordinates, width and height data in b ′, 11c ′ and 11e ′, as shown in FIG.

A table ruled line creating method by the word processor having the above configuration will be described below with reference to the flowchart of FIG.

Now, it is assumed that a vertical ruled line creation command is issued by the coordinate input device 3 with or without selecting a block in the table displayed on the screen of the display device 5. Then, the CPU 1 first checks in step S1 whether or not a block is selected from the block selection information memory 13, and if no block is selected, proceeds to step S2 and considers that the entire table is selected. While changing the block selection information 13 (see FIG. 3) and proceeding to step S3, if a block is selected, an auxiliary line is displayed in the center of the selection range in step S3 based on the block selection information. In this example,
No block is selected, so the second block is displayed in the center of the table.
An auxiliary line is displayed as shown by the broken line in the figure. Next, in step S4, coordinate input, cancel input, and position determination input are performed. If there is a cancel input, step S5
Then, the ruled line creating command is stopped, and if it is not the position determination input, the vertical auxiliary line displayed in step S7 is moved in parallel in the horizontal direction to the input coordinate position, and the process returns to step S4 to perform the input process again.

When the position determination input is made in step S6, the process proceeds to step S8. In step S8, the rectangular information memory 11 divided into two by the ruled line based on the coordinates at which the ruled line is drawn.
b, 11c, 11e are obtained, the obtained rectangular information memories 11b, 11c, 11e are connected to each other by the first pointer chain P ₁ , and new rectangular information memories 11b ′, 11c ′, 11e ′ are secured, and these are connected to each other. the connected by second chain of pointers P _2, further connect the new area of the content information memory 7b by the pointer P _5, each character rectangle information both assigned to the left and right borders with graphic data on a screen To repaint. Next, in step S9, the rectangular information memory 11b, 11c, 11e connected to the first pointer chain P ₁ and the rectangular information memory 11 connected to the second pointer chain P ₂ located on the right of each of them.
b ', 11c', connecting the 11e 'with the pointer P _3. Finally, the rectangle information memory 11b that is connected to the second pointer chains P ₂ in step S10 ', 11c', 11e 'and the other pointer P ₄ and rectangle information memory and the block index memory 12 in accordance with the positional relationship of the block and P Connect with ₆ . In this way, the ruled lines are created in the vertical direction in the designated range of the table on the screen, and the process ends. The processing for the horizontal ruled line creation command is also performed in the same manner as described above.

If the vertical ruled line creation command is issued in the table as shown in FIG. 5, the result of the above ruled line creation processing is coordinate (xi, y1).
A vertical auxiliary line from (x, y4) to (x, y4) is displayed, and the display can be moved by changing the designation of xi in the range of x1 <xi <x3 by the coordinate input device 3, and position determination input can be performed at a desired position. Then, for example, as shown in FIG. 6, a ruled line L ₁ is urged on the entire table, and the blocks b, c, and e are divided by the ruled line L ₁ into b, b ′; c, respectively.
It is divided into c ′; e and e ′. When blocks c and d are selected in the table of FIG. 5 and a horizontal ruled line creation command is issued, a horizontal auxiliary line from coordinates (x2, yj) to (x3, yj) is displayed, and yj Specifies can move the display by changing the range of the coordinate input device 3 by y2 <yj <y3, when performing position determination input at a desired position, the ruled line L ₂ in the range of hatched as shown in example FIG. 7 created, block c, d, respectively c by border _{L 2, c '; d,} d' is being 2 minutes.

As described above, according to the above-described embodiment, the coordinate input device 3 is used to select a range in which a ruled line is to be created in the table and a horizontal or vertical ruled line creation command is issued to vertically or horizontally extend the auxiliary line to a desired position. The CPU1 automatically creates ruled lines based on the rectangular information memory 11 etc. simply by moving to the position and inputting the position, so it is much easier than the conventional method where ruled lines are created for each character length. It is possible to easily and efficiently create ruled lines.

Needless to say, the present invention is not limited to the illustrated embodiment.

<Effects of the Invention> As is clear from the above description, the ruled line creation method of the table of the present invention stores the character and graphic data of each block in the table in the content information memory of the information processing device, The block index memory stores the structural information including the geometrical relation of each block, and the block adding unit creates a new rectangular information memory for the block divided into two by the auxiliary line positioned by the coordinate input unit. A new area of the content information memory is secured, and the structural information in the rectangular information memory of the original and new blocks is updated or generated and stored to display the ruled line at the auxiliary line position.
The pointer setting means connects the original blocks and the new blocks to each other by the first and second pointer chains, and connects the rectangular information memory, the content information memory, and the block index memory to each other based on the new geometrical relationship. Since they are re-connected by the pointer, ruled lines can be created automatically and collectively based on the auxiliary lines that have been positioned, making it much easier and more efficient than the conventional method of creating one character at a time. Can be done.
