Hi,
in this moment I can't understand the table.
I have two list A and B both with 3 item, so I have 9 combinations. why the table has 4 column and not 3?
3 of them have an area of 3 m^2
3 of them have an area of 6 m^2
3 of them have an area of 9 m^2
can I create a data tree with 3 branches sorted by area?
Thank you!…
