It turns out that if you set 'cell-background' you need to set it in
*any* cell. You can set it to None and it will use the default (that may
happen to be an alternating scheme).

I still don't really udertand if the cell object I'm setting the property is
a unique instance for the whole column (I think so) or one instance each
cell.
