CPTableView's addColumn: and removeColumn: do not work properly.
My fix for #637 (hiding table columns) can probably also be used to fix this. I've tried it but ran into some issues with the caching, someone with more experience should probably take a look at it.
So just a follow up on this too, I believe once issue #637 is fixed this one will also be fixed. I think they're suffering from the same bug.
Update: issue #637 is closed and this one I'll leave open because once columns are removed (which seems to work fine) if you reorder the columns by dragging them it breaks. I still believe the issue is related to #637 though.
