You have to create Formula for the Fields.....The formula will be based on your criteria on which you want to display results or not.... Suppose you want nothing to show in Column1 if the Field1(to be shown in Column1) value is 0 then make a Formula.In Formula Editor under the "Suppress" Tab write the following Code.. If myTable.Field1='0' then true now if your query returns 0 in Field1 Column1 will be blank... But the thing to remember,though I am not very sure,is you probably cannot change the design of you report,I mean to say you cannot suppress Column1 with its Caption(if any) and other things....there will be a blank space...
