The columns are auto-created only if there are no columns added.

IMHO it's easy enough to manually add the columns, so I didn't push further. However, I would think it would be pretty easy to make the auto-column creation happen if the generate_columns option is set in the DataSource. The quesiton then is whether they should be before or after the manually added columns.... -- Justin Patrin
