After the list has been created, it will be identified by a blue border. In addition, AutoFilter drop-downs will be automatically enabled for each column in the list and the insert row will be added as the last row or the list. If you choose to add a total row by clicking Toggle Total Row Button image on the List toolbar, a total row will be displayed under the insert row.

When you select a cell, row, or column outside of the list, the list becomes inactive. An inactive list is surrounded by a blue border and does not display the insert row or AutoFilter drop-downs.
