In a normal table view, I’m able to choose and remove items for my lookup column.
In row’s table view where a lookup column is also shown as a table, I’m also typically able to choose and remove items (e.g. “Choose Row” and delete).
But if the lookup column is referencing a Cross-doc table, the ability to choose or remove items in the table view doesn’t exist.
I understand the limitation of not being able to add rows ("+") to a cross-doc table lookup, but I should still be able to choose and remove them.
