6.5.2.11. Using a tableless layout
The languishing tableless version of the Plone default theme has finally been removed from Plone 3.0. However, a product exists which can be used as a substitute.
For people who want to use tableless, you can simply install the Plone Tableless product on top of your site.
If you are submitting a theme to plone.org for public consumption, please specify this as a dependency in your theme product's README.txt file.
