Unfortunately the select doesn't work for me as I'm sure the user will try to click with a mouse and by doing this the rows will be unselected.

Currently I'm considering adding a new initial row where I'll display an OK image for rows that will be imported.

Later I may consider reimplementing this to use the renderer.

Thanks for the initial hints and for the good work you're doing at Apache Pivot. Sincerely,
