See the MediaWiki help on sortable tables.
I have found adding the sorting to the OpenOffice.org Mac OS X Porting Roadmap really useful as you can now sort the table and easily see what is a high priority or already fixed. I wouldn’t recommend it for full bug tracking.
The next feature I’d like to see is row level editing of tables in the wiki, as I hate having to try and find the one or two rows in the table that I want to change.
If you would like to help the port by implementing one of the items on the road map, why not contact the MacPort team? Drop a mail to the mailing list firstname.lastname@example.org (first subscribe by sending a mail to email@example.com. Or say drop by on IRC server irc.freenode.net on the channel #ooo_macport.
