Hey, I'm trying to add a totals row to my table:
and I want it to show the sum (or average) for all columns.
I saw the feature of adding a totals row through the add-ons, but for some reason I don't have this option:
also, I would want it to calculate the totals for only the selected rows (and if none are selected, then for all of them)
Would love some help here
Thanks!
