Hi everyone.
I'm facing a problem that I thought being quite common but, anyway, I wasn't able to find any solutions here in the forum.
What I currently need to do is to set up a straight table with partial sums of the elements within the table, that should be grouped by a specified criterion. You find attached an example of what I mean: in this case elements are grouped by the same "Numero Bolla", and partial total sums are shown at the end of each group.
Thanks in advance.
