What widget are you using specifically?
tw2.jqplugins.jqgrid.jqGridWidget or
tw2.jqplugins.jqgrid.SQLAjqGridWidget ?

The widget was not intended for this. You can try modifying the CSS
yourself once you have run the tw2 resource archiver (see below).

Yes. There is a distutils command that tw2 provides called
archive_tw2_resources. Try running:
$ python setup.py archive_tw2_resources --help
$ python setup.py archive_tw2_resources --force --output=/tmp/
my_resources --distributions=myapp
You'll then need to copy the contents of the /tmp/my_resources folder
into the public/ folder of your tg2 app.
Finally, turn off tw2 resource serving adding the following config to
the bottom of myapp/config/app_cfg.py
base_config.custom_tw2_config['serve_resources'] = False
