Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic page division display for automatically dividing a table according to the position of a horizontal ruled line in the table when a document and a table are prepared by a document processing apparatus such as a word processor, a personal computer, or a workstation. The present invention relates to an editing device. An apparatus that creates and processes documents and tables by the word processor, personal computer, workstation, or the like will be simply referred to as "document processing apparatus" in the present specification.

[0002]

2. Description of the Related Art FIG. 9A shows a state in which a table is contained within one page. FIG. 9B shows a case where the table covers two pages and shows the lower part of the page. Figure 9
(C) is a diagram showing the upper part of the page when the table extends over two pages. A document processing apparatus that creates a document together with a table handles ruled lines as codes in the same manner as characters. As described above, in the document processing apparatus in which both ruled lines and characters are handled in the code system, an editing program for editing tables and documents can be simply and easily created.

However, as shown in FIG. 9 (a), it is preferable that the table fits within one page, but if the table covers two pages as shown in FIGS. 9 (b) and 9 (c), You must create a table that fits on each page separately. That is, it is necessary to restore the tables such as deleting the vertical ruled lines at the bottom and the top of the tables shown in FIGS. 9B and 9C one by one.

Software in a conventional word processor, such as "Ichitaro" and "Pro 100"
Similarly, in "0" and "Oasis" (both are trade names), it was not possible to treat a table having two or more pages as one table. In addition, "Jstar" (workstation manufactured by Fuji Xerox Co., Ltd.) has established a method of automatically printing while sending a part of a table that exceeds two pages to the next page. Has been done. However, even in this method, when an arbitrary page is displayed, the feed from the page including the table to the page to be displayed must be calculated, and an efficient display speed cannot be obtained. That is,
The table preparation device in the conventional example is
SIWYG ... What you see is wh
at you get ... The format of the document being created is always displayed on the screen, and you can edit the document by directly working on that screen.) You cannot handle a table with more than two pages as one table. It was

On the other hand, most conventional document processing apparatuses handle matrix-like tables. A conventional document processing apparatus that can handle a non-matrix-like table is disclosed in, for example, Japanese Patent Application No. 2-320701.

[Problems to be Solved by the Invention]

However, for example, in a table without some of the ruled lines forming a rectangular area, that is, in a non-matrix table extending over two pages, it is not established where to divide the table.

The present invention is intended to solve the above problems, and when one table having two or more pages is created, it is automatically placed at a good break in the table so that each page fits. An object is to provide an automatic page division display editing device for dividing. Further, the present invention is an automatic page division display edit capable of dividing a table in which there are no ruled lines forming a rectangular area, for example, a table extending over two or more pages that is not a complete matrix, so that each page fits. The purpose is to provide a device.

[0008]

An automatic page division display editing apparatus for automatically dividing a page according to a ruled line portion of a table is a document information storage unit (133 in FIG. 1) for storing document information and page attribute information. ) And the ruled line information about the ruled lines of the table and the rectangular area content information about the contents of the rectangular areas of the table (131 and 132 in FIG. 1).
And a layout process for determining the division position of the table based on the document information, the attribute information of the page and the ruled line information, and storing the information of the display range of the table in the document information storage means (133). Means (111 in FIG. 1),
It comprises display means (16 and 17 in FIG. 1) for dividing and displaying the table by referring to the information of the display range of the table stored in the document information storage means (133).

[0009]

[Operation] The document information storage means stores, for example, document information including a display range of a table and attribute information of a page describing the document, such as the number of characters in a line, the number of lines, a line spacing, and a page break mark. The table information storage means stores the position of the ruled line, for example, the start and end points of the horizontal or vertical ruled line, the ruled line information indicating the shape of the ruled line, such as a solid line, a thin line, a dotted line, and the rectangular area surrounded by the ruled line information. Is stored, for example, a margin between a ruled line and a character in a rectangular area and data representing the contents described in the rectangular area. Then, the layout processing means, based on the ruled line information of the table stored in the table information storage means and the document data and page attributes stored in the document information storage means, the document including the table is within the page range. Calculate whether it fits in. Then, the calculated display range of the table is stored in the document information storage means together with the document data. The display means refers to the display range of the table stored in the document information storage means, and automatically displays the table divided into one page together with the document information.

FIG. 3 (a) shows an example that fits on one page, (b)
Is a diagram for explaining an example that fits on two pages, and (c) is a diagram for explaining an example that fits on three pages. 4A to 4C are conceptual diagrams of the memory in FIGS. 3A to 3C. In FIG. 3A, the document including the table fits on one page, and all the data corresponding to the table is stored in the document information storage unit 133. For example, in the document information storage unit 133, when a document including a table fits on one page, "other document data" and "data of the entire table"
And “other document data” are stored in the order shown in FIG. The data of the above-mentioned embodiment is in accordance with Japanese Patent Application No. Hei 2-320701, but the data of the entire table is not limited to the format shown in FIG. It may be in a data format that represents.

In FIG. 3B, the document including the table is 2
All the data that fits on the page and corresponds to the table is stored in the document information storage unit 133. For example, the document information storage unit 133 stores 2 documents including a table.
If it fits on the page, "Other document data",
"Data of the entire table", "Page break", "From the fourth line to the end (data indicating the display range)", and "Other document data" are in the order shown in FIG. Remembered by

In FIG. 3C, the document including the table is 3
All the data that fits on the page and corresponds to the table is stored in the document information storage unit 133. For example, the document information storage unit 133 has three documents including a table.
If it fits on the page, "Other document data",
"Data of the entire table", "Page break", "4th to 6th lines (data indicating the display range)", "Page break", "7th line to the end (display range is Data) ”and“ other document data ”are stored in the order shown in FIG.

FIGS. 5A to 5C are views for explaining a calculation method for calculating a display range for accommodating a table in a page according to the present invention. In FIG. 5A, the ruled line search unit 112 searches the ruled line information storage means 131 for position information of each horizontal ruled line continuous from the left end to the right end in the table, for example, 511 to 514. On the other hand, the page range searching unit 113 searches the page range information stored in the document information storage unit 133, for example, the number of characters in a line, the number of lines, and the space between lines. Next, the layout processing means 111 compares the information indicating the position of the horizontal ruled line searched by the ruled line searching unit 112 and the page range searching unit 113 with the page range information. The comparison of the layout processing means 111 is continued until the boundary of the page range is reached. For example, the layout processing unit 111, when comparing the horizontal ruled line 513 and the page range, exceeds the page range, and therefore determines that the page break 51 is the horizontal ruled line 512.

On the second page shown in FIG. 5B, the layout processing means 111 sequentially compares the page range with the horizontal ruled lines 513 to 517 as described above. When the page range is compared with the horizontal ruled line 514, the page break 52 does not occur because the page range has a margin. Further, in the comparison between the page range and the horizontal ruled lines 515 to 517, the horizontal ruled lines 515 and 516 have a margin in the page range, and the horizontal ruled line 517 has a margin in the page range.
However, since the horizontal ruled line 516 is not continuous from the left end to the right end, the condition for the table break 52 is not satisfied. Therefore, the layout processing unit 111 determines that the horizontal ruled line 515 is the page break 52.

On the third page shown in FIG. 5C, the layout processing means 111 performs the same process as described above, and determines that the end of the table is within the third page. Also,
After finding the breaks 51 and 52 (FIGS. 5A and 5B) of each page, the layout processing unit 111 sets the page break mark and the display range as shown in FIGS. 4A to 4C. The data shown, for example, "Page break" and "From the 4th line to the end" when ending on the second page, and "Page break" and "4" when ending on the third page
Processing for writing data "line from line 6", "page break", and "from line 7 to end" to the document information storage unit 133 is performed.

FIG. 6 is a flowchart for editing a document including a table. In FIG. 6, the editing of the document is started (step 61). Following the editing of the document, the document containing the table is edited (step 62). The document including the table is laid out by the layout processing unit 111 (step 63). The user is determined to display the predetermined page after editing, for example, on the display (step 64). The document including the table on the designated page is not always stored in the page range. Therefore, the layout process is performed so that the table to be displayed is stored in the page range by the calculations shown in FIGS. 5 (a) and 5 (b). By performing such processing, when there is a request from the input device to display page units of a document including a table, page units can be displayed (step 65). Then, when the table or the document is further edited, the process returns to step 62.

FIG. 7 is a flowchart showing a layout process of a document including a table as an embodiment of the present invention. In FIG. 7, first, the layout of the document including the table is started (step 711). Check whether the edited document and table fit within the page range.
This can be understood by performing the calculations shown in FIGS. 5A to 5C as described above (step 71).
2). If the document containing the edited table does not fit on the page, go to the next step. In step 713, when the document covers two pages as shown in FIG. 4B, for example, “page break” is added to “other document data” and “data of entire table” in the document information storage unit 133. insert. Next, the number of lines included in the page is calculated. This calculation compares the page range information with the overall data of the document, including the table, as described above. For example, according to the above calculation, it is assumed that the document including the table has C1 rows within the first page range (step 714).

On the next page, the display range of the document including the table starts from after the first line of the above line to the end of the document. For example, the start line of the display range data is C
In the 1 + 1 line, the end line is "until the end" (step 715). Calculate and see if the rest of the document, including the table, fits on the next page. This calculation is the processing shown in FIG. 5 as described above (step 716). Similar to step 714, the number of lines to be included in the page is calculated (step 717). The end line of the display range data obtained by the above calculation is, for example, the C2 line (step 718). Further, "page break" is inserted after the display range data (step 719). Then, after the "page break", the end line of the page that is the start line of the third page + 1 line, that is, "C2 +"
Display range data "from one line to the end" is inserted (step 720).

When there are remaining documents even after the processing of step 720 is completed, the processing returns to step 716 and the same processing is repeated. In steps 712 and 716, when the document including the table fits within the page range, the process proceeds to step 721, and the layout process of the document including the table ends.

FIG. 8 shows a flowchart for displaying a document including a table in page units, as an embodiment of the present invention. In FIG. 8, the start of page unit of the document including the table is instructed (step 81). Keyboard 1
It is checked whether the page unit document designated by 9 is the entire data of the table. For example, the layout processing unit 111 takes out a document including a table from the document information storage unit 133 and checks whether this is the entire data of the table. If it is the whole data of the table, the process proceeds to the next step. Further, it is checked whether the document information retrieved from the document information storage unit 133 has display range data on the next page (step 83). Document information storage means 1
From the document extracted from 33, the document data from the beginning of the table to immediately before the start line in the display range data is displayed (step 84). The flow from step 82 to step 84 is for displaying one page in a document including a table extending over one page or more.

In step 82, the document fetched from the document information storage unit 133 is not the whole data of the table, that is, the first page of the table,
It is checked whether or not it is the display range data of the table (step 8)
6). If the document is table display range data,
The entire table data is obtained, and only the portion within the display range of the table is displayed on the display 16 (step 87). That is, the pages of data showing the display range on the second page and the subsequent pages of the document are displayed on the display 16. Further, in step 83, if there is no display range data on the next page, that is, if there is no next page, that is, if the document including the table fits within the first page range, the process proceeds to step 88. The table is displayed on the display 16 from the beginning to the end. Next, after displaying in step 84, step 88, step 87, and when there is no display range data in the table in step 86,
That is, if there is no data related to the table, the display of the document including the table in page units is ended.

[0028]

According to the present invention, when a document including a table extending over two pages is created, it is not necessary to perform a process of creating a new table for each page display range. For example, even if the document is inserted before the table and the boundary of the page is in the middle of the table, the page is automatically divided from the horizontal ruled line portion. Since the divided display range is stored as it is in the document information storage means,
When an instruction to display a document including a table in page units, a table automatically divided based on the data indicating the display range of this page is displayed on the display. Therefore, the automatic page division display editing device of the present invention is a widget.
The document can be edited in the wig and the process is performed at an efficient display speed. According to the present invention, when ruled line information and rectangular information are stored separately, even in a table in which some of the ruled lines forming a rectangular area are not present, for example, in a table that is not a complete matrix and extends over two pages, It can be automatically divided to fit each page.
