Thanks Tommi. I have certainly found it hard to find gtk samples.
Usually I look for an app that does what I want then grab the source for
it and see how they did it. But I didn't have any for this!

Ok, so the renderer has a global setting as well as the per-column settings.

My main problem was forgetting that the 'column' variable on the API
calls really has nothing to do with the physical column number. I
couldn't see how you could address two renderers with the same column
number. But you dont, the 'column' is really an arbitrary index and has
nothing to do with the actual column number.

Thanks for the help!
