Table component more advanced than JTable
Is anyone aware of any JTable alternatives that would implement some of the missing functionality, in particular the ability to "group by" a particular value? Add summaries (totals, averages, etc)?
There's plenty of those types of components in the .Net world (and coming from a PowerBuilder background I myself got very used to its incredibly flexible DataWindow table/grid component), so I was hoping there are some advanced table components than JTable for Swing as well....
Any links or suggestions would be much appreciated,
P.S. Preferably open-source components.
