I need to write an application that includes, in one of the data entry 
window, a sort of spreadsheet table with 9 editable coulumns and 8 
calculated, not editable columns.

Is NSTableView the correct approach? I tried with Data Browser but they 
are lacunous in the data entry handling.
(i.e. it's not possible to move the focus ring from one column to 
another one, it's not possible to make a selection in the vertical 
direction, ... ).

I'm still considering to use FB for developing that application. I don't 
want to abandon it in favour of Cocoa, if possible.

Michele.
