How to hide the blank rows in Webi 4.1

Hi,

Is it possible to hide the empty rows in Webi 4.1 when you check the table property "Avoid duplicate row aggregation"? I tried 'Hide when empty' and hide when following formula is true (isnull), but didn't work. Please see the screen shot. Please let me know if you have any suggestions.

Thank you,

Charvi.
