The question is a little bit unclear, but I think you may be helped by FocusPanel:

http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/FocusPanel.html

Wrap your CellTable in this FocusPanel and you can do setFocus() on that instead. The FocusPanel has addKeyPressHandler(), so you can capture further keypress events there, also when your textbox has lost the focus.
