/**\class FWTableWidget FWTableWidget.h Fireworks/TableWidget/interface/FWTableWidget.h

 Description: ROOT widget for representing data in a tabular form where the data is accessed via a FWTableManagerBase

 Usage:
    This widget creates a table made up of cells where the representation of the cells is controlled by the FWTableManagerBase instance
    passed to the FWTableWidget's constructor. If the data for the FWTableManagerBase changes, the view is automatically updated. See
    the documentation for FWTableManagerBase for further details.
