Bonjour, "Horizontal" is not the word but I don't know how to explain... and by extension how to find in archive of list...
Maybe an example ? I have this +-------+-------+ | a | b | +-------+-------+ | 1 | 1 | | 1 | 2 | | 1 | 3 | | 2 | 1 | | 2 | 2 | | 3 | 1 | +-------+-------+ Their is any why to obtain something like that : +-------+--------+ | a | b | +-------+--------+ | 1 | 1,2,3 | | 2 | 1,2 | | 3 | 1 | +-------+--------+ Based on a group by or something...
