[Zope] sorting a table

I am looking for a sorting mechanism similar to that in the ZMI, where I can click on the header "ID" to let the objects be sorted by the id. This I would like to implement in a HTML table, which is laid out like this: id title date I would like to make the headers appear as links, which reloads the current url with something like this: http://localhost:8080/current_page?sorttype=title How do I have to format the dtml-in tag to use this url for sorting? I already tried this: dtml-in blabla .. sort=&dtml-sorttype; without success.
