"compare something like Swing's JTable to WinForms' DataGrid"

Do you actually mean the DataGrid? Because the WinForms "DataGrid" was deprecated in 2002 with .NET 2.0 which added the DataGridView. The software I work on is Windows Forms and I can't say I've had any issues like you describe with the DataGridView. I was able to create a control derived from it that does all the heavy lifting for customizations(Visual, interaction, cell spanning, etc.), of which we had a lot. Enough that we were exploring third party controls, but found we would have to customize those ourselves anyway, so I just wrote my own control based on DataGridView to save us the licensing.

WPF had it's own DataGrid control from the start, though I can't comment from experience on it's versatility, I'd assume given WPF's nested-content approach it is surely at least more flexible than the DataGridView.
