wikitable

I'm using wikis a lot but every wiki I tried so far lacks support for tables. The wikis are able to show tables, but building a table using lots of pipes “|” sucks. What I want to develop (or learn that such a this already exists) is a small application which creates tables which then can be included in wiki pages.

The first step could be a small standalone application which manages the tables. The tables should also be available as a HTML-snippet (just the table, html- dory body-tags). This snippet can be included by most wikis.
