Explanation:

In Access, a Totals row is a way to sum the entries of columns and display the result in the last cell of column, making an entire row.

For adding a Totals row:

In the Home tab, locate the Records group and select Totals from the options. The totals row will appear at the end of the datasheet.

We can click each cell of the totals row to select type of the total we want. This means for columns having numerical entries, totals cell will give the sum of all entries and for the text values, a count of total entries will be displayed in the totals cell.
