How to add a total to a column

How to add a total row to a column in a simple question/table?

My table requires totals at the bottom of several columns of figures.

If they’re simple sums, the easiest way is to use a Pivot visualization, which will calculate the totals as part of the display.

With a SQL question you’d use UNION ALL to combine 2 queries, one to output the rows and another to compute the totals.

Thanx for that, seems odd that it is not a standard feature in table view.
