Yes, that is exactly what I was thinking. You can register a mouse button listener on the header and call getHeaderAt() to determine which header was pressed. Then you can call getHeaderBounds() to get that header's bounding area. Finally, you can call mapPointToAncestor() on the TableViewHeader to convert the header bounds to display coordinates for displaying the context menu (you can call getDisplay() on the header to get the display).
Let me know how it goes.
