A table with dynamic number of rows and scroll in two directions.

I'm trying to make a table for a round robin tournament. Like on a picture.

Do you have any ideas how to make it?

1. Is it possible to make such a table using standard FF widgets? The DataTable widget cannot have a dynamic number of rows and columns.

2. Is it possible to make the table scroll in two directions, so that everything to the right of the green line and everything below the red line can be moved?
