That function was used in the example just because there was a bug with represent for referenced fields, I guess that bug is fixed and this function is now useless.
The case is that a SQLTable (which is the base of powerTable) was not showing format or representation, instead it was showing None or the referenced ID. I will make some tests to see if the reference bug is fixed.
