All actions on a sheet are performed within the area referred to as the workspace.
By default, the workspace in a new sheet consists of 10 columns and 20 rows.
Workspace borders expand automatically if you insert more rows or columns than the current workspace has.
To expand the workspace manually, do the following:
•Double-click a cell in a row or column in the inactive area that you want to include in the workspace.
•Right-click on the row/column header you want to include in the workspace and run the Double click to add N rows and N columns context menu. The number of rows and columns is suggested by MyOffice Spreadsheet.
•Select any cell in a row or column before the expansion area. To expand the workspace by one or multiple columns, press Tab. To expand the workspace by one or multiple rows, press Enter.
