Removing a background colour

Hi.

I have a table visual. One of the column colour backgrounds has been changed from the default 'no colour' to white. Is there a way to change back to 'no colour' ?

This is the table visual:

It uses an alternating grey/white row background and then a colleague changed the formating of a column, but when the value is 0 I'd like to see the alternating grey/white row colour. Is there something I can do to resolve this issue, or should I just re-create the visual again?

Thank you 🙂
