SSRS 2012 - Hide Duplicate Rows

Question

I have tried these 2 methods separately ,

1. Row Visibility

   =IIf(Previous(Fields!name.Value) = Fields!name.Value, True, False)

For Above , do i need to add every field?

2. HideDuplicates in Row Properties, that works, but it leaves behind blank rows.

My 2 Questions.

For 1., do i need to add every field?

For 2.,Im lost on how to remove the blank rows?

Thanks,

Add a Filter on the table properties so that blank rows are not in the data set.
