Using display:none seems to have some mixed results, but it's gotten me closer. Even though it hides the data, the column heading seems to stay behind

Thanks Riyaz Here in green I have added the =null condition statement, but where on the pink highlight do I now indicate to hide the column? The condition format seems to only cover font, cell alignment, order, size and data format. I don't see the hide attribute.

I would like to do this, but it does not seem possible in Cloud OTBI 2. Apply Conditional Formatting to Hide Empty Columns
