You are not supposed to override SetColLabel(), you are supposed to
override GetColLabelValue().

When you use PyGridTableBase, there could potentially be thousands of
columns, and wxPython does not want to keep track of thousands of
column labels.

Therefore, when wxPython needs to display a column label, it calls
GetColLabelValue(self,col). It is up to you to return the value to use
for that column.
