To insert / delete row, make sure the resultset is updatable.
1. Move the cursor to the specific position
rs.moveToCurrentRow();
2. Set value for each column
rs.moveToInsertRow(); // to set up for insert
rs.updateString("col1" "strvalue");
rs.updateInt("col2", 5);
...
3. Call inserRow() method to finish the row insert process
rs.insertRow();
4. To delete a row, move to the specific position and call deleteRow() method
rs.absolute(5);
rs.deleteRow(); // delete row 5
5. To see the changes call refreshRow()
rs.refreshRow();
