Abstract

PURPOSE:To easily change the format of a table even after inserting an oblique line or the like in the table prepared by a table preparing function by changing the position or the length of the segment of the oblique line or the like line-plotted by a drawing function when changing the ruled line data of the table prepared by the table preparing function. CONSTITUTION:A line data storage means 2 storing the data inputted from a line data generating means 1, a matrix data generating means 3 specifying a number of row and a number of column and instructing to generate the ruled lines constructing the table, a ruled line data storage means 7 generating and storing the ruled line data based on the data stored in a matrix data storage means 4, a line data changing means 6 changing the data in the line data storage means 2 corresponding to the ruled line data changed by a ruled line data changing means 5, or the like are provided. And the ruled line data are generated based on the table data prepared by a matrix specifying, and the start point and the end point of the segment prepared by the drawing function are changed according to the change of the ruled line data keeping the relative position relation. Thus, when changing the part or all of the table prepared by the table preparing function, the lines written in the table by the drawing function are changed accordingly.

Description

[Detailed Description of the Invention] [Industrial Application Field] Invention 1 A desktop publishing system (hereinafter referred to as D
[Prior art] Table editing devices such as DTP that can freely create tables in a document and perform various editing operations on them [Prior art] Although there is a need for improved operability, conventional table editing devices require a method to draw rectangular, vertical, and horizontal lines in sequence when creating a table in a document. There is a method of sequentially specifying the number of rows and columns, called the tabulation function.In the former case, a rectangle created by drawing lines is recognized as one cell, and the table can be managed independently for each cell within it. In the latter case, the table is managed row by column [Problem to be solved by the invention] However, when a table is created by drawing lines, the table cannot be managed by rows or columns in the table. To insert or delete rows or columns in a table, since there is no concept of matrices, you must correct the parts of the table that change due to insertion or deletion by moving or redrawing lines. Also, when a table is created by specifying a matrix, it is only possible to edit row by row and column by column, and it is difficult to insert diagonal lines. It has nothing to do with the created figure, and the size of the table is changed or the position of the line is moved. It is necessary to change the figure created using the drawing function. [Means for solving the problem] In order to solve this problem, the present invention (methods for solving the problem) generate
The present invention also includes a changing means for changing the starting and ending point data of the line segment created by the drawing function while maintaining the relative positional relationship as the ruled line data is changed. If there are horizontal lines, vertical lines, diagonal lines, etc. drawn using the plotting function in a table created using the tabulation function, if you change part or all of the table created using the plotting function, the table will be changed accordingly using the drawing function.

The operation of the table editing apparatus of this embodiment configured as described above will be explained below using the flowcharts shown in FIGS. 6 to 8.

In FIG. 6, when table editing is instructed manually using the mouse 25 or keyboard 26, the starting point coordinates are acquired in step S31, and the ending point is acquired in step S32. Then, in steps S33 and S34, it is stored as line data in the line drawing management area 23-2 shown in FIG.
4 or more displayed in T32 (Yo) The procedure for manually processing the line segment, which is called the plotting function, is as follows. First, in step Sj5, the coordinates of the upper left end of the matrix area that coincides with the outer frame of the table specified by the mouse 25 are obtained.

In step 83B, the lower right corner coordinates are acquired in the same way as in step S35.In step S37.
, the coordinate data acquired in S36 is stored in the matrix management area 23-
1 and displayed on the CRT 32. Step S39
, In S40, data on the number of rows and the number of columns is obtained from the keyboard 26 and stored in the matrix management area 23-1. In step S41, the matrix management block 51,
Setting the row management block 52 and cell information storage area 53 In step S42, the position information of each cell is calculated, and in step S43, the calculated cell position information is stored in the cell information storage area 53. Although the matrix management area shown in FIG. 3 is completed, in step S44, the data for the vertical lines and horizontal lines that make up the table is generated based on the data in the matrix management area 23-1, as shown in FIG. 5. After displaying the ruled lines according to the ruled line data stored in the ruled line management area 23-3 in step S45, Section 8 describes the processing procedure when changing the format of the table.
The explanation will be given according to the flowchart in the figure, but first, step S
In Step 46, the editing range is obtained using the mouse 25.In Step S47, cells and borders within the editing range specified in Step S46 are searched. (Yo) Compare the coordinate data of the editing range with the coordinates of each line and each ruled line to determine whether or not it is the target.The result of the search
In step 34, change the cell and border data to be changed.
8, and a message to that effect is displayed in step S49. In step S50, the data area 73 regarding the ruled line data created in step S44 is acquired.
At the same time, the data in the data area 63 and line management block 62 regarding the line data generated in step S33 is changed. In addition, when the ruled line data is changed, one piece of information of the cell in the cell information storage area 53 is also changed. When certain coordinate data is changed, the data at the same coordinates are also changed. For example, If the end points of the line segments at the intersections of the ruled lines overlap, the coordinates of the end points of the line segments are also changed as the intersection points move. Displaying a line based on data and line data is a secondary problem.The explanation will be based on a display example.Figure 9 shows an example of changing the position of a horizontal line in a table. , the vertical ruled lines and the horizontal ruled lines are plotted using the function according to the flowchart in Fig. 7, and the diagonal lines
This is a line created using a so-called drawing function according to the flowchart in the figure.4 In this state, when the second horizontal line from the top is specified as a movement target with the mouse 25 (step 846), steps S47, S48, and 549 are executed. After processing, it is determined that the second horizontal line and diagonal line from the top are the ones to be changed, as shown in Figure 9(a).
However, when the ruled line to be changed is moved upward as shown in FIG. 6(b), the data in the management block 72 and data area 73 are changed, and at the same time, the joining position of the diagonal line is also changed. The data in the management block 62 and data area 63 are changed. And Fig. 9(c)
Although it is displayed as shown in Figure 10 (see Figure 10), it shows an example of display when changing the size of the table.As in Figure 9, the vertical and horizontal ruled lines and diagonal lines are created respectively, and may be changed. If you specify the entire table as a target and change the position of the bottom left end point as shown in Figure 2 (B), the vertical and horizontal ruled lines will also move while maintaining the similarity, and at the same time the position and length of the diagonal lines will also move, as shown in Figure 2 (C). [Effects of the Invention] As described above, when changing the ruled line data of a table created by the tabulation function, the position of line segments such as diagonal lines drawn by the drawing function Now you can easily change the format of the L table after adding diagonal lines, etc. to the table created using the tabulation function.
