This question has little or no relation to EJBs as it is almost purely
a client side (browser/HTTP/HTML) issue.
One way to do this is using DHTML layers/frames (this would be the
equivalent of what David mentioned, a separate "frame", though DHTML
give much more flexibility and looks much better than plain frames).
Each of these layers can have it's own request to the server to get
different information and so could be refreshed separately (though I
haven't tested browser support for this). There is also the possibility
if your data is images, you can refresh images separately from the page
(again, may be browser compatibility problems).
The biggest challenge you face is browser compatibility.
However, if you intend to have each cell be able to be refreshed
separately, you might run into inefficiencies, etc.
