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.
