 subclasses can implement. In python is very easy and powerful to pass
 around references to methods but gets messy very quickly because it's hard
 to find where is defined the method that will be called. Every time you
 are tempted to pass a method reference, consider using instead an abstract
 method or a signal.

 I changed SmartTable so it has the same ctor arguments as TableView
 (SmartTable relies on having do_fill_in() method in passed class)
