I suspect you formatted your sheet as a table just for appearance sake.
Using the Format as Table button on the home tab does more than just apply an
autoformat tho. You can't apply Subtotals to a 'table' - under Table Tools
Design on the Ribbon, in the Tools group, click Convert to Range. Subtotals
will then be available.
