You can easily add or delete rows and columns. First, select the row or column that you want to delete or that you want to insert a row or column next to, and do one of the following:
For a row: Right-click and choose Add Row Above, Add Row Below, or Delete Row from the pop-up menu that appears.Choose where to place your new row.
For a column: Right-click and choose Add Columns Before, Add Columns After, or Delete Column from the pop-up menu that appears.
