This test case has child rows that are all open after the table loads:
live.datatables.net/voyanulo/1/edit
Every child row has an "extn_class" which I would like to use to control the text color of the last numerical part of the child row (the remaining text of the child row should stay red). My goal is to change the text color to orange if Extn >= 5000. For main rows this is controlled by using 'createdRow' and "$(row).find('td:eq()')", but I'm not sure how to do this for child rows analogously.
