Issue Description

we need to insert some new row data in middle sheet, but not provide similar "Sheet.InsertRow" interface;
"Sheet.CreateRow" could delete prev position row data, this did not meet my expectations;
I can only shift row data and then create new row data, but this action very slow when insert a lot of row data;

Did you try to move rows to another sheet and then insert them, starting from new position?
