While this might seem to duplicate behaviour I believe having this code in a delegate is a better solution. - the logic in BaseTableModel is view logic not model logic - letting the custom delegate determine the formatting is much more efficient then letting the default delegate do many virtual calls to detemine how the model wants it formatted.
