I have a `UITableView` with a couple sections. When I use `UITableViewStylePlain` it does **not** put any separator on the bottom of the headers, while each cell **does** have a separator. This is the look I want, *however*, I want the behavior of `UITableViewStyleGrouped` that when you scroll the header moves with the scrolling rather than staying in place.

But when I switch to `UITableViewStyleGrouped` a separator shows up between the header and the first cell.

How can I get rid of this separator?
