I'm not sure why the highlight would appear only after the keyboard has
been used. Why not make it appear always, even in a newly-constructed

I'm not terribly concerned about how it's rendered, as long as the selected
column and row are apparent. If the selected row is more prominently
indicated than the selected column, that's okay.

If it's going to work much like wxGrid, then why not follow a spreadsheet
model for navigation? For example, pressing Enter in a spreadsheet doesn't
enter edit mode.

It is a two-dimensional table. Therefore, it could seem surprising if
navigation differs gratuitously from gnumeric or open-office calc (or
ms excel).
