Hello, thank you for your answer. Indeed it was pretty easy, I hadn't understand well what all the fields were doing!
Another question if I may:
I have a table on which I want to be able to add new rows. It works well (see picture 1), except for when the table is empty (see picture 2 -> it does not allow me to modify any field + the column names are not showing in the table).
Any insights on how to make it work even with an empty table? Or should I create a new topic? Thanks!
