When a UITableView of type UITableViewStyleGrouped has a background view that is a non-default color or pattern image on the iPad, the rounded corners have an ugly extra line, sort of like a bevel effect or drop shadow:

Does anyone know of any way to get rid of the extra line at the bottom of the table?
The default separator style for iPad is
UITableViewCellSeparatorStyleSingleLineEtched. This is different from the iPhone’s default ofUITableViewCellSeparatorStyleSingleLine.If you would like to remove the bevel, set the
separatorStyleof the view toUITableViewCellSeparatorStyleSingleLine.Note that the default separator style in iOS 5 for both devices is SingleLineEtched.
