Automatic column creation is disabled

I’m trying to upload local data to a new datatable on my app with uplink, however it cannot update the first row as the table has been created with ‘automatic column creation’ disabled. I can’t seem to find any way to control this setting for a datatable.

I have noticed this problem in the past on and off, and have found that the classic editor never had this problem but the beta editor did. Now, I can’t seem to find the classic editor to do my workaround.

Any info on why this happens, or how to control the ‘automatic column creation’ for a datatable would be super useful.

In the new editor, go to Settings (the gear icon on the left) and then Data Tables. The checkbox you’re looking for is there.

Amazing, thank you! Can’t believe I missed that.
