I set tableView.editing=YES, and I receive 2 callbacks for each row in the

UITableViewCellEditingStyleNone.
(2) -tableView:canMoveRow
The problem boils down to this: If a UITableView doesn't have inner-width
autoresizing enabled, the table won't get the 'move row' ability.
Q: How can I set this property on the UITableView programmatically?

FWIW, for setting the UINavigationBar color you can specify any color as long
