HOW TO HIDE A ROW ON WEBI REPORT WITH 0 AND NULL VALUES

Hi gurus,

I am doing a webi report, the report have 3 columns and in some rows the report has in column 1 NO VALUE (it means the cell is empty or null) in column 2 0 and in column 3 0 again. For me 0 or NULL is the same and I need to hide or delete these rows but I don't know how.
