How do I delete a column or row from a table in Asana

@Phil_Seeman you are right. Sorry @Jonathan_Healy - it seems I missunderstood your question. So here we go:

To delete a column you have to select the whole column (drag your mouse over it) then in the summary bar at the bottom it will say «1 column selected» (you can also select more than one) and you have the trash-icon to delete the column. Same process to delete rows. See screenshot below.
