It turns out the YUI datatable control works fine on GAE.
The issue was that I had not added enough data to the control to see
the scroll bars show up. After I added additional data, the scroll
bars showed as expected.
Thanks for the responses.

Your suggestion is a good one to review the css and HTML in both the
local and GAE version. I am very puzzled there would be any
difference because when I use the appcfg.py routine the local files
are uploaded to GAE. There should not be any difference between the
two sets of files.
