How to resize UITableView in UITableViewController with section header

Question

I've got a grouped UITableView in a UITableViewController and I want to resize it horizontally.

I tried many different ways but none of them was perfect.

What I've tried:

1.) Overriding - [UITableView setFrame:], but it didn't move the headers of the sections and there are black areas on both sides (because there isn't anything behind the table view).

2.) Overriding - [UITableViewCell setFrame:], but it still doesn't move the headers (which is important).

3.) Calling - [self.view setFrame:] from UITableViewController, but it doesn't do anything.

If you've got any idea how to solve it please share it with me!
