How do I add multiple rows and columns to an existing table in Word? I can only use the insert one at a time in the Table menu

For Microsoft word 2003 is not possible to add insert multiple rows or colums after you have created the table!

Benn11 is incorrect.

If you select multiple rows in the table then Select Table>Insert Rows from the menu, it will insert the same number of rows as selected. The only thing you can't do is insert more rows then currently exist in the table. The same goes for columns.

Sorry for the wrong advice I tried a number of options but could get it right
