CellRenderers are assigned by column rather than by row, so it's not 
possible to have a different kind of CellRenderer in each row displayed 
by a TreeView in a particular column.

However, such a thing would probably be possible if you wrote your own 
CellRenderer class which wrapped itself around the existing ones, or 
mimicked their functionality, so that you could achieve the same effect. 
Unfortunately there is no way to achieve such an effect with TreeView 
without writing your own CellRenderer.

Alternatively, you could try constructing a scrollable widget containing 
a Gtk::Table and using that instead, but obviously that presents 
completely different challenges and may not be at all suitable.
