Programmatically add a blank row at the end of a InfoPath repeating table

Code snippet to add a blank row as last row in a InfoPath repeating table. 

//Get the repeating table node

XPathNavigator Group = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:AnalysisGroup/my:AnalysisTable", NamespaceManager);

//Get the Iterator object to iterate the node to last row

XPathNodeIterator rows = Group.Select("/my:myFields/my:AnalysisGroup/my:AnalysisTable", NamespaceManager);

                      

//Loop to move the cursor to last row

for (int counter = 0; counter < rows.Count; counter++, rows.MoveNext()) ;

//clone the last row and insert it after that

rows.Current.Clone();

rows.Current.InsertAfter(rows.Current);

//move the cursor to the last row

rows.MoveNext();

                      

//Set all the fields in the row to blank

rows.Current.SelectSingleNode("my:ItemDesc", NamespaceManager).SetValue("");

rows.Current.SelectSingleNode("my:Tax", NamespaceManager).SetValue("");
