You can quickly calculate totals on table columns and perform other functions when you use table formatting on your data. To add totals to a column that is part of a table, add a row for the totals, and then in each cell on the totals row, use the functions that are provided in a pop-up menu.
Click anywhere in the table.
On the Tables tab, under Table Options, select Total Row.
In the total row, click the cell in which you want to calculate a total, and then click the double arrow that displays the pop-up menu.
In the pop-up menu, select the function that you want to use to calculate the total.
Tip: Formulas that you can use in the totals row are not limited to the functions in the list. On the pop-up menu, click More Functions to display the Formula Builder. You can enter any formula that you want in any cell on the totals row.
