Hi John, Expenses uses a SortedHeader Class that overrides Header<String>, then adds the arrow via HTML. If I could actually run the code (it doesn't compile), I'd tell you how well it works.
Is your API going to be strictly UI, or will it also involve getting the data? If the latter, I STRONGLY encourage you NOT to build it around ListDataProvider. Local data is easy to sort, it's the data on a server that's "interesting".
