The deleterow function in NPrinting applies to removing a blank row between the last line of data and a formula in an Excel template. This is typically done to remove the gap between data and totals. See the following for more information: Totals at the Feet of Columns in Tables
If there is a row in the straight table itself you want remove, you will have to do that in the QlikView object properties.
Are you looking to remove the totals row from your straight table? If so, just select "No Totals" from the Total Mode box on the Expressions tab in the object properties.
