Since tables are often used to organize numerical data, it makes sense that we can perform mathematical calculations with tables.

First, you need to insert a row or column where you want the total to appear.

Then, click to place your cursor in the cell at the end of the row or column that you want to add.

Next, click the AutoSum button () on the Tables and Borders toolbar. Your sum will appear in the selected cell.

The great thing about the AutoSum tool is it’s easy to update the sum. If the text in the column changes, just right-click on the sum and click Update Field.

Word will then re-calculate the column for you.

Another way to calculate a row or column is to click the Table menu and click Formula after your cursor is in the cell where you want the sum to appear. (You can see the Formula dialog above.)

If your cursor is at the end of a row of figures, Word will automatically fill in the =SUM(LEFT) formula. If your end of a column of figures, Word will automatically fill in the =SUM(ABOVE) formula for you.

You can choose the format for your number (for example, setting the number of decimal places or choosing percentage sign). Once this is done, click OK to complete the operation.

Your sum will now appear in the cell you selected just as if you had used the AutoSum button on the Tables and Borders toolbar.
