Tree like widget in GWT CellTable

I have a requirement of a tree like widget in a CellTable and so far I haven't found anything that works seamlessly. So, I was evaluating celltree.

As most of my functionality is ready with CellTable开发者_开发技巧 and as tree like requirement has come very late into the development I want to incorporate it somehow in the CellTable itself rather than re-writing the whole UI again.

Is it possible to do with CellTable?

If you are using CellTable implement a custom Cell and feed it an implementation of TreeViewModel. Easier said than done, but that's the basic approach I would use.
