In financial reports, we generally do not want to see a currency symbol on every number.

The standard going back my entire career is $ on the first record and then on the total, usually at the bottom.

I know how to include or exclude currency symbols entirely. But I do not see how to do this for just top and bottom rows. 

Example:

Product Category	Sales
Furniture	$       1,500
Groceries	1,200
Stationery	1,950
Total	$       4,650
