By default, a new file contains three sheets. Only one page of a file is active at a time. To activate another sheet, select Focus->Sheets and scroll to the desired sheet. If there are too many open sheets, their shortcuts won't be seen on the screen. To gain access to other sheets, use the scrolling buttons.

To add a new sheet to the workbook, select Insert->Sheet. The program will add new sheet to the open file before the active window. The new sheet will automatically become an active one.

If you no longer wish to use a sheet or want to remove a blank sheet from the workbook, you can remove it by selecting Edit->Delete Sheet. eCell will ask you to confirm sheet deletion.

The default sheet names are Sheet1, Sheet2, etc. You can rename them at any time. To rename the sheet, select Format->Rename Sheet. After the dialog box appears, type the text you want, and then select “Rename”. The maximum number of symbols in sheet names is 20 symbols including spaces.

Each sheet contains 65536 rows and 256 columns. These are constants, and they do not depend on the number of added or removed rows and columns.

To add a row or rows, select the number of rows you want inserted through Select->Rows and then select Insert->Columns. To add a new column or columns, select the number of columns you want inserted through Select->Rows and then select Insert->Rows.

To remove a row or rows, select the rows you wish to delete, and then select Edit->Delete. To remove a column or columns, choose the same function. If you remove a row or columns by mistake, select Edit->Undo.

In eCell, you can also change the width of a column. Column width is calculated by the number of pixels on the screen within a column. By default, column width is 36 pixels. To set the column size, select Format->Column Width, type the size you want, and then select “OK”. You can also use the toolbar button to invoke the column size dialog.
