Have you looked at the Huge grid table example in the demo, the one with
the 100 million cells? It demonstrates how to use a  table for the grid.
I've made an app inspired by that example which loads stuff on demand from
a bsddb and stores changed items immediatly back to the db - seems quite
similar to what you intend to do.

The Grid table is basically sitting in between the grid that the user sees
and whatever storage backend you have. The grid asks the table for data to
be inserted in cell at some coordinates, the table does whatever it deems
necessary and answers. Even better, the grid asks the table about what
attributes each displayed cell should have (color, read-only, custom
editor, the whole lot).
