All actions on the sheet are performed within the workspace. Documents created in MyOffice Spreadsheet have a default workspace of 26 columns and 300 rows.
The workspace borders are extended automatically if copied rows/columns are pasted onto the sheet and the number of rows/columns exceeds the number of rows/columns in the workspace.
To expand the workspace manually, do one of the following:
•Double-click to select any cell in the row or column to be included in the workspace.
•Right-click the row/column header to be included in the workspace and run Insert Rows: n/Add Columns: n from the context menu.
•Select any cell in the last row/column of the workspace. To expand the workspace by one or more columns, press Tab. To expand the workspace by one or more rows, press Enter.
