Scrollbars in treetable

I am looking for a component that does pretty much what treeTable is providing. It just needs to additionally display vertical and horizontal scrollbars. The scrollbars should be right and below of the data section in order to keep tree on lefthand side and headers on top always visible.
To put treetable into panel brings only partial success (for vertical scrollbar) - when scrolling horizontally the tree disappears.
Any ideas whether that is possible?
