My need :
I have a pivot table with many many expressions.
Those expressions could be grouped by big categories.
I would like to set a label for each categories on top of each expression label.
It would look like this :
|group 1||group 2|
|expr 1||expr 2||expr 3||expr 4|
I nedd that presentation in an Excel export based on this pivot table.
I haven't find any evident solution, so if someone as THE killer trick for that, i would be very grateful !
