System for displaying desired portions of a spreadsheet on a display screen by adjoining the desired portions without the need for increasing the memory capacity

摘要

A data processing apparatus includes a spreadsheet data storing section for storing spreadsheet data, a spreadsheet creating section for creating a spreadsheet consisting of at least one row and at least one column and a display section for displaying the spreadsheet on a screen. Additionally, the data processing apparatus includes an inputting section for designating a row or a column to be subjected to a non-display operation, a non-display controlling section for removing row or column data in the non-display operation, and controlling the display section to display a modified spreadsheet by moving rows or columns previously located adjacent to the removed row or column into adjoining relation. Further, a recovery display controlling section enables the restoring of data of a previously removed row or column to the displayed spreadsheet when the inputting section designates implementation of a recovery display operation.
