Make tables sortable in Plone 2.1

Plone has a "Safe HTML" transform that filters the thead element in tables, making it impossible to create sortable tables when editing your content. Fortunately this is easy to fix.

  • Go to the 'site setup' and click the Zope Management Interface.


  • Find the portal_transforms in the list of content and tools.

portal_transforms

  • Once in the 'portal_transforms', go to the 'safe_html'
  • In there, add 'thead' and '1' to the table of valid HTML.

  • After you save it, restart your zope.  You should have sortable tables!
