I have prepared a simple demo to show the use of cell editors an a per row basis.

This demo shows a table with key/value pairs. The values can be edited.
There are two types of values: strings and bools. Dependent of the type,
either a CellRendererText or CellRendererToggle is used to show and edit
the value.
This is done by connecting the visibility of a CellRenderer to a
ListStore column.
