When you press the tab key in a TableTree, the next control gets focus
rather than the next column in the table. Is there any way to setup a
TableTree such that tab takes you to the next column in the table?

Thanks
Carolyn

Unfortunately there is no default tab implementation in SWT/JFace. For our project we created our own for the JFace TableViewer using SWT TraverseListener's.
Our implementation allows you to tab betreen the cell editors of the table. Using a TraverseListener on the controls of all editors it was possible to create it. However there are some issues we had.

First when you tab to the next (or previous with SHIFT-TAB) cell editor you need to force an apply changes on the open cell editor. I'm not sure if this is still in isue, but if it is you can call refresh(null) to force an apply changes before you call editElement(Object, int) to start editing the next cell editor.

Second you need to set the 'doit' instance variable of the TraverseEvent you receive in the listener method to false. Otherwise the tab you pressed will also be handled by the cell editor control.
