Adding totals allows you to automatically calculate sums, averages, or other summary values for your columns. It helps you understand your data more clearly by giving you instant insight into overall performance or progress. Instead of manual math, the table does the work for you.

This matters because totals help you make informed decisions with confidence. When large amounts of information are involved, summaries reveal trends and key numbers at a glance. They simplify analysis and save time, especially when you're working with finances or inventory.

For example, if you’re tracking expenses for the month, adding a total at the bottom of the “Amount” column immediately shows how much you’ve spent. It helps you stay within budget and adjust plans as needed.

Another real-life scenario is managing orders and wanting to know how many items have been completed. A total under the “Status” column gives you a quick snapshot of your progress, making planning and reporting much more straightforward.
