Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table creating apparatus capable of creating a desired table arbitrarily.

[0002]

2. Description of the Related Art Conventionally, when attempting to create a table in a word processor or the like, horizontal ruled lines and vertical ruled lines are appropriately combined and assembled in a table format.

Further, a fixed table whose form has been determined in advance is first simply read by a table creating operation to automatically set the table, and then a table editing operation is performed on this table as needed. Some could even add columns or rows to the table.

[0004]

However, in the method of creating a table by combining horizontal ruled lines and vertical ruled lines as described above, the creating work is extremely complicated, and a table of a desired form can be easily created. There was a problem that it could not be created.

Further, in the case of changing the form of the table by performing the table editing work on the basic table as described above, the table creating work and the table editing work are independent. In the above table creation work, a table of a predetermined form can be easily created, but when this table is not what the operator desires, a new table editing work is designated and the table is complicated. There is a problem that it is necessary to perform table editing work, and at the time of creating a new table, a desired table cannot be created easily and immediately.

An object of the present invention is to make it possible to easily and immediately create a desired table at the time of creating a new table.

[0007]

The means of the present invention are as follows. A mode designating means for arbitrarily designating a table creation mode indicating a new creation of a table, and at the time when the designation is made by this mode designating means, the above table creation mode indicating a new creation of the table is entered, and this table creation In the mode, a predetermined number that was previously determined as the initial number of table items in the horizontal and vertical directions of the table is specified as the number of table items in the horizontal and vertical directions of the above table, and then the above horizontal direction. And a table item number designating means for designating a desired number of table items by changing the initial number of table items in the horizontal and vertical directions of the table by an arbitrary change designation operation of each table item number in the vertical direction, The table in the horizontal direction and the vertical direction in which the number of table items in the horizontal direction and the vertical direction is specified by the table item number specifying unit according to the specification by the table item number specifying unit in the table creation mode. item And the display position specified by the position specification operation with the cursor in the table creation mode, and the table image of the table newly created by the table creation means under the table creation mode. And display means for displaying.

[0008]

The operation of the means of the present invention is as follows. When a table creation mode that indicates new creation of a table is arbitrarily specified, the table creation mode is entered, and under this table creation mode, a predetermined number of table items in the horizontal and vertical directions of the table is predetermined. The specified number is automatically specified as the number of table items in the horizontal and vertical directions of the table, and the horizontal direction can be changed by any subsequent operation of specifying and changing the number of table items in the horizontal and vertical directions. And the initial number of table items in the vertical direction is specified. In accordance with this designation, a table in which the number of table items in the horizontal and vertical directions is determined by the number of table items in the horizontal and vertical directions designated by the table item number designating means is created, and this newly created table is created. The table image is displayed at the display position designated by the position designation operation with the cursor in the table creation mode.

Therefore, when a new table is created by designating the table creation mode, at the time when the table creation mode is designated, first, a predetermined number of horizontal items and vertical items are automatically set as initial values. Since the operator can change this value based on this and perform a specifying operation to obtain the desired number of table items, a new table based on the specified content can be immediately created, and The created table can be displayed at a desired display position designated by the display cursor.

If it is determined in step A12U that the content (CYR) of the vertical cursor position register has reached the uppermost line position (first line), the cursor operation becomes invalid and the cursor position is moved. Instead, the cursor stays at the top line position.

Next, the execution key e associated with the specification of the tabulation mode
The process until the basic table pattern is displayed on the page layout display section DL of the display section 12 by the operation of k will be described with reference to the flow of FIG.

When the execution key ek is operated, step A
At 21, it is determined whether or not the table mode is set.
If not in the tabulation mode, the operation input of the execution key ek is determined by the normal document creation process, and the process returns to the normal document creation process flow. Further, in the tabulation mode, it is checked in step A22 whether or not the content of the tabulation mode flag (F) is "0". If it is other than "0", step B31 in FIG. Start processing. When the content of the tabulation mode flag (F) is “0”, the contents of the tabulation mode flag (F) are updated (0 → 1) before step A23.
~ The process of step A30 is executed. That is, in step A23, "3" is set in the lateral item number register for storing the lateral item number (n) in the RAM 17, and in step A24,
"3" is set in the vertical item number register for storing the vertical item number (m) in the RAM 17, and the RAM 17 is set in step A25.
Predetermined three item horizontal sizes (c1, c2,
In each item horizontal size register storing c3), "1" indicating that the horizontal item size is the minimum digit, that is, one digit
Is set, and in step A26, each item vertical size register for storing three predetermined item vertical sizes (l1, l2, l3) in the RAM 17 has a minimum vertical item size, that is, one line. Is set to 1, and in step A27, the remaining item horizontal size (c4, c5, ... c20) in the RAM 17 is cleared in each item horizontal size register, and in step A28, the RAM is stored.
Each item vertical size register that stores the remaining item vertical size (l4, l5, ... l30) in 17 is cleared, and in step A29, the cursor position (CX
The contents of the cursor position register for storing R, CYR) are set in the table forming start position register for storing the table forming start position (X0, Y0) in the same RAM 17, and R is set in step A30.
The content of the cursor position register that stores the cursor position (CXR) in the AM 17 is incremented by "+1". After this, in step A31, the contents of the table mode flag register in the RAM 17 are incremented by "+1" to become "F = 1".

Thereafter, by the processing of steps A32 to A44, the basic table pattern display processing as shown in FIG. 10A is executed according to the data set in the steps A23 to A30. That is, the length (Lc) of the horizontal ruled line is obtained in step A32, the length (Ll) of the vertical ruled line is obtained in step A33, and the respective values are set in the corresponding registers in the RAM 17. Here, in the above steps A23 and A24, the horizontal item number register and the vertical item number register in the RAM 17 are respectively set to "3" (n = 3, m).
= 3) is set, and in steps A25 to A28, R
Of each item horizontal size register and item vertical size register in the AM 17, the item horizontal size (c1, c2, c3),
And "1" is set only in the registers that store the item vertical size (l1, l2, l3), respectively,
Data (Lc = 6, Ll = 6) indicating the length of “6” dots for both the horizontal rule and the vertical rule are set in the corresponding ruled line length registers in the RAM 17.

Next, at step A34, the table start position data (X0, Y0) stored in the table start position register in the RAM 17 is converted into the address data (x0) of the display memory 20.
0, y0) is set in the display memory address register in the RAM 17. Further, in step A35, R
After the content (i) of the table memory address register in the AM 17 is cleared and "i = 0" is set, a vertical ruled line / horizontal ruled line drawing process (ruled line display process) is started.

In the line drawing process, first, step A
At 36, the table memory address (i) of the table memory address register in the RAM 17 is incremented by "+1", and at first "i =
1 ", and the address register becomes an address value indicating the storage address of the item vertical and horizontal size (l1, c1) of the table memory 16. Next, at step A37, it is checked whether or not the content of the item lateral size (c1) in the table memory 16 designated by the address value is "0". Here, when the content of the item horizontal size (c1) is “0”, step A
Line drawing processing of horizontal ruled lines after 40 is entered, and "0"
If not, in step A38, vertical line drawing processing is executed. Here, since the content of the item horizontal size (c1) in the table memory 16 is “1” and the content of the vertical ruled line length register is “L1 = 6”, the work is stored in the display memory 20. A total of 7 dots are turned on from the address (x0, y0) indicated by the display memory address register in the RAM 17 as a display start position to a position shifted by 6 dots in the row direction (downward in pattern development). The display pattern of the vertical ruled line is expanded. After this pattern development processing, in step A39, the working R
The content (x0) in the X direction of the display memory address register in the AM 17 is updated, and the value obtained by adding “1” to the content of the item lateral size (c1) in the table memory 16 is the display memory 2
It becomes a new address (x0) in the X direction of 0. After this display memory address update control, the process returns to step A36 again, and the table memory address (i) of the table memory address register in the RAM 17 is incremented by "+1" and becomes "i = 2". It is checked whether or not the content of the item horizontal size (c2) in the table memory 16 designated by the address value is "0". Such a vertical ruled line drawing process is repeatedly executed, and the above step A37 is performed.
If it is determined that the content of the item horizontal size (ci) in the table memory 16 designated by the address value is "0", the vertical ruled line drawing process is terminated, and step A
A horizontal ruled line 40-A44 is drawn. Here, the horizontal direction of the table plotting start position on the display memory 20 (X
Direction) address is Ax0, Ax0, Ax0 +
The vertical ruled lines of a total of four 7-dot lines are drawn from the respective addresses 2, 2, Ax0 + 4, Ax0 + 6 as starting points, and then the horizontal ruled line is drawn. This horizontal ruled line drawing process is performed in step A40.
Then, the content (i) of the table memory address register in the RAM 17 is cleared, and "i = 0" is set.
At 41, the table memory address (i) of the table memory address register in the RAM 17 is incremented by "+1", and at first "i =
1 ", and the address register becomes an address value indicating the storage address of the item vertical and horizontal size (l1, c1) of the table memory 16. Next, in step A42, it is checked whether or not the content of the item vertical size (l1) in the table memory 16 designated by the address value is "0". Here, when the content of the item vertical size (l1) is "0", the ruled line processing is ended, and when it is not "0", the horizontal ruled line drawing processing is executed in step A43. Here, the content of the item vertical size (l1) in the table memory 16 is “1”,
Moreover, since the content of the ruled line length register is “L1 = 6”, the address (x0, y) indicated by the display memory address register in the working RAM 17 is displayed on the display memory 20.
0) is the display start position, and a total of 7 positions from that position to the position shifted by 6 dots in the digit direction (to the right in pattern development)
A horizontal ruled line display pattern in which dots are turned on is developed. After this pattern expansion processing, in step A44, the contents (y0) of the display memory address register in the work RAM 17 in the Y direction are updated, and the table memory 16 is updated.
A value obtained by adding “1” to the content of the item vertical size (l1) in the above becomes a new address (y0) in the Y direction. After this display memory address update control, the process returns to step A41 again, and the table memory address (i) of the table memory address register in the RAM 17 is incremented by "+1" and becomes "i = 2". The content of the item vertical size (l2) in the table memory 16 specified by the address value is "0".
Is checked. Such horizontal ruled line drawing processing is repeatedly executed, and in step A42 described above,
When it is determined that the content of the item vertical size (li) in the table memory 16 designated by the address value is "0", the ruled line drawing processing is ended. Here, assuming that the address in the vertical direction (Y direction) of the table development start position on the display memory 20 is Ay0, Ay0, Ay0 +
Line drawing processing of a total of four 7-dot horizontal ruled lines is performed using the addresses 2, Ay0 + 4, Ay0 + 6 as starting points.

By carrying out such line drawing processing of the vertical ruled lines and the horizontal ruled lines, on the page layout display section DL of the display section 12, the cursor designated position is taken as the tabulation start position, and FIGS. As shown in (A), a basic table pattern is displayed in which the number of vertical and horizontal items is 3 × 3 and each item is one character area.

When the basic table pattern is displayed, the address (CXR) in the X direction of the cursor positions (CXR, CYR) stored in the cursor position register is "+1" in step A30. The cursor position on the display screen is as shown in FIG.
As shown in, the position is moved to the right by one dot from the tabulation start position (X0, Y0), that is, the first item position in the horizontal direction.

(2). Horizontal item number increase / decrease processing (Fig. 6,
FIG. 10 (B)) Next, based on the basic table pattern displayed on the page layout display section DL of the display section 12, the cursor key c
The number of horizontal items is increased / decreased by operating r and cl, and the specific processing operation is shown in FIG.
This will be described with reference to the flow.

When the right (.fwdarw.) Direction cursor key cr is operated after the above basic table pattern is input, the number of horizontal items is increased as shown in FIG. 10B.

That is, the right (→) direction cursor key cr is 1
When it is operated twice, at this time, the contents of the tabulation mode flag (F) in the work RAM 17 have already become "1" instead of "0", so the processing after step B11 in FIG. 6 starts. . In the process shown in FIG. 6, first, in step B11, it is determined whether or not the content of the table mode flag (F) in the work RAM 17 is "1". Here, the execution key e
When it is determined that the number of operations of k is "1", in step B12, the table memory address register in the work RAM 17 is loaded with the item vertical and horizontal sizes (l1, c
The table memory address (i = 1) indicating the storage address of 1) is set, and the content of the item horizontal size (c1) in the table memory 16 designated by the address is checked in step B13. If the item horizontal size (c1) is "1" and the item has already been registered, step B
After it is judged in 14 whether the number of items exceeds the maximum number of items “20”, in Step B15,
The table memory address (i) of the table memory address register in the working RAM 17 is incremented by "+1", and the above step B1 is executed.
Returning to the processing of 3, the contents of the next item horizontal size (c2) are examined. Item horizontal size (ci) in step B13
When it is determined that the content of the item horizontal size (ci) specified by the table memory address (i) is “0” (unregistered) at the time of determining the content of, the number of horizontal items is determined in step B16. Is determined (X0 + (i × 2) ≦ 44). If it is determined that the number of horizontal items can be increased, then in step B17 the table memory 16
"1" is set in the storage area of the item horizontal size (ci) designated by the table memory address (i) in the table, and the number of horizontal items (n) in the memory 16 is "+" in step B18.
1 ”, the ruled line display processing is started from step A32 of FIG. An example of increasing the number of horizontal items in this case is shown in FIG.
It is shown in (B).

When the left (←) direction cursor key cl is operated after the basic table pattern is input or the horizontal item number increasing process is performed, the horizontal item number decreasing process is performed. That is, when the left (←) direction cursor key cl is operated once, the tabulation mode flag (F) already in the working RAM 17 is also present at this time, as in the above-described horizontal item number increasing process.
Since the content of is not "0" but "1", the processing after step B21 in FIG. 6 is started. In the process of FIG. 6, first, in step B21, it is determined whether or not the content of the table mode flag (F) in the work RAM 17 is "1". Here, if it is determined that the number of operations of the execution key ek is “1”, in step B22, the work R
The table memory 1 is stored in the table memory address register in the AM17.
The table memory address (i = 20) indicating the storage address of the item 6 vertical / horizontal size (120, c20) is set, and in step B23, the table memory 16 designated by the address is set.
The content of the item horizontal size (c20) in is checked. If the content of the item horizontal size (c20) is "0", indicating that no item is registered, whether the item number has reached the minimum item number "1" in step B24. After it is judged whether or not it is, in step B25,
The table memory address (i) of the table memory address register in the work RAM 17 is decremented by "-1", and the above step B2 is executed.
Returning to the processing of 3, the content of the next item horizontal size (that is, before the next one horizontal item) (c19) is examined. This step B2
Item horizontal size (ci) specified by table memory address (i) when determining the contents of item horizontal size (ci) of 3
When it is determined that the content of the item is "1" (already registered), in step B26, the item horizontal size (ci) specified by the table memory address (i) in the table memory 16 is stored. The storage area is rewritten to "0", and in step B27, the number of lateral items (n) in the memory 16 is "-1".
After that, the ruled line display processing after step A32 in FIG. 4 is started. By the processing of steps B21 to B27, the number of horizontal items is sequentially reduced according to the operation of the cursor key cl.

As described above, the cursor keys cr, cl
According to the operation of, the number of horizontal items is increased / decreased based on the displayed basic table pattern.

Next, when the execution key ek is operated again (second operation), the cursor position moving process shown in steps B31 to B33 of FIG. 6 is performed, and then the cursor keys cd and cu are operated. By doing so, the vertical item number increasing / decreasing process as shown in FIG. 7 is performed according to the operation.

That is, when the execution key ek is operated after the horizontal item number increase / decrease process, whether the content of the tabulation mode flag (F) is "1" in step B31 of FIG. Whether or not (whether or not it is the second execution key ek operation) is determined. Here, when the content of the tabulation mode flag (F) is other than "1", the processing after step C31 of FIG. 7 is started, and when the content of the tabulation mode flag (F) is "1". In step C32, the Y address (Y0) of the tabulation start position (X0, Y0) stored in the tabulation start position register is set to "+1", and the updated address value is set in the cursor position register. , The cursor position (CXR, CYR) is updated. As a result, the cursor on the display screen is displayed at a position one dot below the tabulation start position (X0, Y0), that is, the first vertical item position, as shown in FIG. After this cursor position control, in step B33, the tabulation mode flag (F) of the tabulation mode flag register is rewritten from "1" to "2", and then the ruled line display processing of step A32 and thereafter in FIG. 4 described above. to go into.

(3). Vertical item number increase / decrease processing (Fig. 7,
11) Next, based on the basic table pattern displayed on the page layout display section DL of the display section 12 or the table pattern in which the number of horizontal items is increased / decreased in FIG. 6, a cursor key is used. By operating cd and cu, the number of vertical items is increased / decreased, and its specific processing operation will be described with reference to the flowchart of FIG.

When the process shown in FIG. 6 is performed based on the basic table pattern, and the down (↓) direction cursor key cd is operated after the execution key ek is operated as described above, the number of vertical items is changed. Increase processing is performed. That is, when the down (↓) direction cursor key cd is operated once, the working R
Since the content of the tabulation mode flag (F) in the AM 17 is already "2" as described above, the processing after step C11 in FIG. 7 is started. In the process of FIG. 7, first, in step C11, it is determined whether or not the content of the tabulation mode flag (F) in the work RAM 17 is "2". Here, if it is determined that the number of operations of the execution key ek is “2”, then in step C12, the item vertical size (l1, c1) of the table memory 16 is stored in the table memory address register in the work RAM 17. The table memory address (i = 1) indicating the storage address of the item is set, and in step C13, the item vertical size (c
The contents of 1) are examined. Here, the above item vertical size (l
If the content of 1) is "1" and the item has already been registered, it is determined in step C14 whether or not the number of items exceeds the maximum number "30", and then in step C15. At this time, the table memory address (i) of the table memory address register in the working RAM 17 is incremented by “+1”,
Returning to the processing of step C13, the contents of the next item vertical size (l2) are checked. When determining the content of the item vertical size (li) in step C13, it is determined that the content of the item vertical size (li) designated by the table memory address (i) is "0" (unregistered). Then, in step C16, it is possible to increase the number of vertical items (Y0 +
(I × 2) ≦ 60) is determined. If it is determined that the number of vertical items can be increased, the table memory address (i) in the table memory 16 is determined in step C17.
"1" in the storage area of the item vertical size (li) specified by
Is set, and after the number of vertical items (m) in the memory 16 is incremented by "1" in step C18, the ruled line display processing of step A32 and subsequent steps in FIG. 4 is started. An example of increasing the number of vertical items at this time is shown in FIG.

When the up (↑) direction cursor key cu is operated, the number of vertical items is reduced. That is, when the up (↑) direction cursor key cu is operated once, the contents of the tabulation mode flag (F) in the work RAM 17 have already been changed to “Similar to the above-described vertical item number increasing process. 2 "
Therefore, the processing after step C21 in FIG. 7 is started. In the process of FIG. 7, first in step C21,
