Hide empty rows in Webi

HI I need to hide empty rows in a webi report.

The issue is i am using variables.

Name     Jan     Feb     Mar

MM       200                 9

PP                                  

VV        590      100             

The MM, PP, VV are manually entered names & each row has different variables with a measures with different variables.

Table format --> hide dint work

Creating a show/hide variable dint work as i have different variable for each row (40 rows, 40 variables)

Thanks
