i need to hide all those blank row in my whoel worksheet. found this code in
another thread but realise that this hide the row if that column is blank.
however, what i want is to only hide the row if whole row is w/o data and not
particular column w/o data. so hw can i modify this code or is that any
other code to acheive this?

Sub Tester()
On Error Resume Next
Range("A1:o20").Columns(1).SpecialCells(xlBlanks). _
EntireRow.Hidden = True
On Error GoTo 0

End Sub
