JPH03116267A - Table frame extending method for word processor - Google Patents

Abstract

PURPOSE:To improve the operability in the title method by deciding the presence or absence of a ruled line showing the lower right end of a table based on a cursor position and inputting by copying a ruled line equal to the next current line to the cursor position when the presence of the lower right end is confirmed. CONSTITUTION:A keyboard 1 is provided together with a control part 2 including a CPU, various types of memories 3 for storage of a control program, for storage of input sentences, and for a dictionary part, etc., a CRT 4, and a printer 5. When the cursor position pointing the character input position is set on a ruled line which divides a table frame, the part 2 decides whether a position right under the cursor position is coincident or not with a ruled line showing the lower right end of a table. If so, a ruled line equal to a current line is inputted by copying to the line following the cursor position. As a result, the ruled line of the table frame can be automatically extended.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for extending a table frame in a word processor.

(b) Conventional technology In a word processor that forms a table frame divided by ruled lines and inputs characters into the table frame,
When attempting to input characters larger than the size of an already partitioned table frame, it is desirable that the table frame is automatically extended as the characters are input. The prior art disclosed in Japanese Unexamined Patent Publication No. 57-59229 frames a block editing area with indent marks, and if characters are input while being framed by the indent marks, block editing using the indent marks is possible. Automatic extension is performed depending on the area, and after character input, the indent mark is replaced with a ruled line, allowing the input of characters larger than the size of the pre-divided table frame (in this state, the frame by the indent mark). .

However, in this prior art, if characters are input again with the table frame displayed with ruled lines, the processing unit does not recognize the table frame in the ruled line area as a block editing area. However, the table frame cannot be automatically extended.

Therefore, it is necessary to return the table frame of the ruled line section to the indent mark again and input characters in the frame state of the indent mark, which is a bad operation.

(c) Problems to be Solved by the Invention The present invention solves the problem that, as mentioned above, when excessive characters are input into the table frame of a ruled line section, the table frame is not automatically extended, resulting in poor operation. do.

(d) Means for Solving the Problems The present invention is a method for extending a table frame partitioned by ruled lines as characters are input into the table frame. When the cursor position that indicates the position is on the ruled line that partitions the table frame, it is determined whether the position immediately below the cursor position is the ruled line that indicates the lower right edge of the table, and if it is the lower right edge, then It is characterized by copying and inputting the same ruled line as the current line on the line next to the cursor position.

(e) Function: As described above, it determines whether the line indicates the lower right edge of the table based on the cursor position, and if it is the lower right edge, copies the same ruled line as the current line to the next line after the cursor position. By inputting information, table frame borders can be automatically extended.

(f) Examples The method of the present invention will be described in detail below with reference to drawings showing examples thereof.

FIG. 1 is a block diagram showing a schematic configuration of a Japanese word processor using the method of the present invention, and FIG. 2 is a diagram showing the layout of a full character layout type Ben-touch type keyboard. In FIG. 1, 1 is a keyboard, 2 is a control unit including a CPU, and 3 is for storing control programs.

Various memories for input text storage, dictionary section, etc. 4 is CR
T, 5 is a printer. Sentences input from the keyboard 1 are stored in a text memory constituting a memory 3 by the action of the control section 2, and are displayed on the CRT 4 together with the text. This text is printed by the printer 5 by giving a print command, and is also stored in a floppy disk provided as an external memory in the memory 3, so that it can be used for subsequent printing.

This word processor has the following block editing functions. To explain this function, let's start with the third
If you want to reserve a space for pasting a photo on the right side as shown in the figure, indent 1 on the left side of that space and press the key 11.
By writing a diamond-shaped indent mark 61 in advance by touching , this indent mark 6
The area sandwiched between 1 and the left margin mark 62 is edited as one block (when inputting, a line break is made when the cursor comes to the indent mark; deletions and additions are made within this block, etc.). Note that the indent mark is not involved in printing. In addition, in order to avoid the trouble of writing a large number of indent marks 61, by writing an indent mark 61 on the upper line, indent marks are automatically written one after another in the position directly below each line break on the lower line. It seems like it's going down.

Furthermore, although this embodiment has a tabulation function, as shown in FIG. Block editing is possible in the area between the ruled lines. As shown in FIG. 5, when the table is in an unfinished state, that is, when the horizontal line at the bottom of the table is not drawn, the text input is at the right end of the row corresponding to the bottom end of the vertical line 64 of the table. When it reaches the end, the vertical line is automatically extended downward, and the block editing area of this table is enlarged. This enlargement function also applies to the area sandwiched between the margin mark 62 and the vertical line 64. Such an enlarging function is exactly the same as the enlarging function of a block editing area by automatically writing an indent mark to the next line.

Therefore, the expansion of the block editing area in a table as described above is possible even when the table is closed in advance by drawing a horizontal line at the end of the table as shown in Figure 4. The rows of the lower horizontal line are moved down one row at a time.

On the other hand, when the bottom end of the table is closed with a horizontal line as shown in Figure 6, the left margin mark 6
When text is entered into the block editing area sandwiched between 2 and the vertical line 65 of the table, and the characters are filled to the right end of the area of the last row of the table (same as the horizontal line), without extending the table, The indent mark 61 is displayed in its extended position instead of the vertical ruled line, and if text input continues after that, the block editing area is enlarged by adding the indent mark in the same way as described above. There is.

In order to execute the block editing area enlarging function of this embodiment as described above, it is necessary to specify the position in the table from the ruled line pattern. First, the tabulation function in the method of the present invention will be briefly explained.

The operation procedure for drawing ruled lines is as follows. That is, the user moves the cursor to the position on the CRT 4 screen where the starting end of the ruled line should be, and then touches the ``1 ruled line'' key 12. In response to this, the control unit 2 executes a predetermined program and displays a pattern to guide the selection of the type of ruled line (thin line, thick line, double line, broken line), and displays the desired type of ruled line. By operating the corresponding numeric keypad, a cross pattern of the corresponding line type is displayed at the cursor position, and by touching the cursor repeat key 13 in the desired direction to draw the ruled line, the ruled line is drawn in that direction.

Codes related to displaying or printing such ruled lines are 16-bit codes, and a pattern for displaying ruled lines or a font for printing ruled lines is assigned to each code. The upper 8 bits of the 16-bit data indicate that it is a ruled line hood.
The font pattern can be identified using the lower 8 bits. In this example, the printing font is 32x32 and CRT.
Each screen display font is composed of a 24×24 dot matrix, but in the case of a ruled line font, a very limited portion of these matrices is used. That is, as shown schematically in FIG. 7(A), a region 71.degree. indicates a ruled line portion extending upward from the center, and a region 72.degree. indicates a ruled line portion extending downward. Area 7 indicating a ruled line portion extending to the left
3 and area 74 indicating the ruled line portion extending to the right, the ruled line information of each area (none, thin line, double line,
(bold line) is assigned to 2 bits each from the upper side of the lower 8 bits of the 16-bit code. And since no ruled line = 001 thin line 201. Double line: 10 and thick line: 11 represent this, the lower 8 bits are ooooooooo
00000101 has no ruled line in that part, 00000101 has a horizontal thin line extending across the entire left and right width of the font, o
ooooo.

001 is a horizontal thin line that appears only in the right half of the font (a broken line is drawn as a continuation of this line) as shown in Figure 7 (c).
, 11111111 consists of a thick cross-crossing part as shown in FIG. 7(D), and 0100000 consists of a double line extending in the entire vertical direction of the font as shown in FIG. 7(E).

Therefore, from the food written in the text memory, it is possible to identify that the display content corresponding to the code is a ruled line (based on the upper 8 bits) and the type of ruled line (based on the lower 8 bits).In other words, the cursor position If the lower 8 bits of the written data in the text memory, which is checked in relation to If the lower 8 bits are 01000100, it is determined that there is an inverted pattern as shown in FIG. .

Now, the control section 2 that performs the enlargement of block editing as described above.
The processing will be explained based on the flowchart of FIG.

Characters are written into the text memory by touching the character key 14, and are displayed on the CRT 4, and the cursor is moved each time a character is input. If you continue to apply the force shown in Figure 9 (a), the characters between them will eventually become - and the cursor will be at the indent mark 61 position. The control unit 2 reads the contents of the text memory at the cursor position, and determines whether the right end of the block has been reached or not. -This is, for example, otoiooo equivalent to vertical ruled lines.
It looks like o) is written or not. Character writing and cursor advancement are repeated until the right end is reached, and when the right end is reached, the control section 2 next checks whether that position is the right end of the last line of the block. This reads the contents of the next line immediately below the cursor position from the text memory, and the read code is shown in Figure 9 (a).
If it is a block end defining mark (indent mark) as shown by the dotted chain line, it is assumed that it is not the right end of the last line of the block, and the cursor K is moved to the left end of the same block in the next line.

On the other hand, if there is no block end regulation mark, the block end regulation mark in the line of the current cursor is copied and written to the corresponding position of the next line. Insert a line with a copy of the mark between the lines) [Figure 9 (b)]. If the block end regulation mark is an indent mark, the block editing area will be enlarged one after another by repeating this process.To stop this enlargement, move the newly copied indent mark to the cursor movement key 15 ” key 16, deletion is prevented.

After copying the indent mark as shown in Figure 8,
This copyability or the presence or absence of a table in the inserted line, in other words, the presence or absence of a ruled line code, is checked, and then it is checked whether this is the end of the table [The end of the table is shown in Figure 7 (to), (
The code is as shown in (g). If it is not the end of the table, even if there is a ruled line code, it will wait for key input as in the case of indent marks.

Therefore, in the case of a table with an open bottom end as shown in FIG. 5, the vertical ruled lines are extended in the manner of copying the indent mark.

Such a process of extending the table downward is performed in the same way when characters are input into a table whose lower end is closed in advance (a horizontal line at the lower end is drawn in advance) as shown in FIG. To explain this based on Figure 10 (a), the bottom line in the table (a horizontal line can fill one line by itself, so no characters are written in the horizontal line; therefore, the bottom line in the table is a horizontal line). When characters are input to the right end of the block (one line above the line above) and cursor K reaches the position of the vertical ruled line, the control unit recognizes that the right end of the block has been reached and changes the display below the cursor position. Read the code of the part (indicated by the chain double-dashed line) from the text memory. Then 01000
100, it is determined that the current cursor position is the right end of the last line of the block, and as shown in FIG.
Insert a line with ooo in two places. The insertion row is checked to see if there is a table, but since there is no code indicating the end of the table, such as the codes in Figure 7 (f) and (g), the cursor is advanced to the inserted row and the next one is inserted. The line's key is now waiting for human power. In this way, even when writing into a closed table, the block editing area is expanded downward.

On the other hand, in the case shown in Figure 6, the table is not extended unnecessarily.
When the cursor K is positioned on the vertical ruled line 65 on the left side of the table in the next upper row, the control section 2 displays the code on the display section below the cursor position [Fig. It is determined that it is not the right end of the last row of the block,
Move cursor K to the left end of the next line [Figure 11 (b)]. Then, as the character input progresses further and the cursor K reaches the display area in the lower left corner of the table, [Figure 11 (box)] This time, it is determined that it is the right end of the last row of the block, and the block end regulation mark of the row is marked. Insert the copied row between the next row [Fig.
Replace the hood of 0001 and 01000100 at the bottom right of the table with the code of the indent mark 61, move the cursor to the left end of the replaced line, and enter the state of waiting for key input.

Thereafter, as shown in FIG. 6, the block editing area is expanded using the indent mark 61. In addition, Figure 11 (
Condition d) is not actually visually recognized.

Note that this process is performed by providing a margin directly below the table, and adding the title of the table to this margin.

This is to facilitate the entry of annotations, etc. Therefore, the sixth
The block editing area is not enlarged by adding an indent mark to the vertical ruled lines inside the table as shown by the two-dot chain line in the figure.

(g) Effects of the Invention As is clear from the above description, the present invention determines whether or not it is a ruled line indicating the lower right edge of a table based on the cursor position, and when it is at the lower right edge, the line next to the cursor position is By copying and inputting the same ruled line as the current row, the table frame ruled line can be automatically extended, so you can input excessive characters even in pre-divided table frames without worrying about the table frame. This improves operability.
