Include total row in design grid?

To include a total row in a design grid, you typically need to enable the total row feature in your grid settings or configuration options. This row can automatically calculate sums, averages, or other aggregate functions for the columns specified. In many grid frameworks, this is done by simply toggling an option or adding a specific component that handles the calculation and display of totals. Ensure you test the functionality to confirm that the totals update correctly as data changes.
