i write keypresslisner for textbox when i press Down And UP arrow the focus is set to be cellTable And also we still press down and up arrows its highlites the rows in celltable

Ans:

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. TheFocusPanel has addKeyPressHandler(), so you can capture further keypress events there, also when your textbox has lost the focus.
