Is it possible to ad a overlay such as a"glaspane", which dims and blurs the table content, and displays a widget (such as for displaying a loading state) using the ViewPortLayer mechanism? and if so how woul dI go about implementing something like this?

Not sure what you mean with "ViewportLayer mechanism". But regarding overlays, yes we have the IOverlayPainters that you could use. You can implement and register an IOverlayPainter via NatTable#addOverlayPainter(IOverlayPainter). It gets the GC and an ILayer (which is typically the NatTable instance itself) so you can render what ever you like on top of a NatTable.

I was referring to the ViewPortLayer from this image https://www.eclipse.org/nattable/images/NatTable_Architecture.png
