Abstract

PURPOSE: To provide a document processor by which an operator can more easily and more surely perform the cell expansion and contraction processing in a local specified table and to provide the method therefor. CONSTITUTION: When the cell of a table A is selected from the table A and a table B within the same edition area displayed on a display means, the table A including the selected cell is recognized as the aggregate of the continuous cells and the expansion and contraction of the selected cell is instructed, the cell within the table A expands and contracts and the cell within the table B is not entirely changed although the table exists within the same editing area, because the selected cell and the table A including the selected cell are recognized as the aggregate of continuous cells based on the instruction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus and method capable of handling editing of a table.

[0002]

2. Description of the Related Art In table group editing in a conventional document processing apparatus and method, when a plurality of tables exist in the same editing area, that is, in the same fixed frame or the same floating frame, the editing area When you select an arbitrary cell in any table and perform expansion / contraction processing, not only related cells in the same table as the selected cell but also related cells in a different table from the selected cell will be selected. If it was in the same edit area as the selected cell, it was affected by the expansion / contraction processing of the selected cell.

An example of the operation of cell expansion / contraction processing in this conventional technique will be described with reference to FIG.

In FIG. 18 (a), in the same fixed frame,
That is, it is assumed that two tables A and B exist in the same editing area. Here, when the cell at the upper right of the table A is selected and highlighted and the cell is expanded rightward, not only the table A but also the table A as shown in FIG.
All cells in the third column in both Table B and Table B will be stretched as well as the selected cell.

[0005]

However, in the above-mentioned conventional example, all the related cells in the same editing area as the cell selected by the operator for performing the expansion / contraction process are expanded / contracted in the same manner. , To expand or contract only a cell of a certain local table, for example, to expand only the cell of the third column of table A in FIG. 18,

Then, the table containing the cells expanded downward is recognized (in this case, table A), and the actual cell expansion / contraction processing associated with the expansion of the cell in the right is performed on the ruled lines / cells included in table A. It is done only for. FIG. 16 (b) shows the state after expansion / contraction of cells, but when the cell in the right middle of table A is expanded downward, only the cells in the same row of table A are expanded and table B is expanded. The cell of remains unchanged.

FIG. 17 shows a CPU in the device according to the present invention.
It is a flowchart of the table unit cell expansion / contraction process of FIG. In this flowchart, the operator uses the pointing device 5
The process is started immediately after operating the to select an arbitrary cell and determining the expansion / contraction position of the cell. First, in FIG. 17, in step S1, a rectangle including all ruled lines (hereinafter, rectangle A).
Is calculated. Then, in step S2, a circumscribed rectangle (hereinafter, rectangle B) of the table including the cell that has started the cell expansion / contraction operation is obtained. Then, in step S3, it is checked whether the rectangle B is smaller than the rectangle A. If the rectangle B is smaller, step S
Go to 4. Otherwise, namely rectangle A and rectangle B
If they are the same, the normal cell expansion / contraction process is performed in step S8, and then the process ends. In steps S4 to S7, cell expansion / contraction processing is performed in table units. First, step S
In step 4, it is checked whether all the ruled lines have been checked, and if they have been checked, the process proceeds to step S7. If not, it is checked in step S5 whether the ruled line being processed is a ruled line in the rectangle B (whether the ruled line is included in the table subject to the table unit cell expansion / contraction processing). If the ruled line is not included in the rectangle B, the process returns to step S4 to move to the next ruled line. If it is a ruled line in the rectangle B, the ruled line is moved or expanded / contracted in accordance with the table unit cell expansion / contraction process in step S6, and the process returns to step S4. If the checking is completed for all ruled lines in step S4, the cell restructuring process associated with the table unit cell expansion / contraction process is performed in step S7, and then the process ends. When documents etc. exist in the cell, the adjustment is also performed at the same time.

By adding a means for designating the "whole cell expansion / contraction mode" to this embodiment, it becomes possible to perform the table unit cell expansion / contraction of the present invention and the normal cell expansion / contraction by switching the modes. . The flowchart in that case can be expressed by replacing the condition of S3 of FIG. 17 with "if rectangle B <rectangle A and not" total cell expansion / contraction mode "".
