I don't think that's the right approach. The dataprovider is meant to
provide the data, and not really know how its displayed. Sure the
sortabledataprovider is kind of on the fance, but I think sorting is more of
a data artifact rather then a presentation one. I think the breakage into
columns should be handled by the display component. The rows container can
pull the iterator out and just pass that to the columns container...a
orderedrepeatingview inside a dataview? Just thinking out loud...
