how to use rowid in filter for datawindow?

I try to use filter to filter data in datawindow, like

dw_1.SetFilter("column = value")

dw_1.Filter()

then I can get data from this datawindow like:

GetItemNumber(row, column_name)

GetItemString(row, column_name)

but I want to filter expression like

"column = value and rownumber>10"

How to use datawindow row number for filter?
