[KLUG Members] Wikis

[MPs]

I was just wondering if anyone here has any experience setting up and
running Wiki based web sites. In particular I was wondering which wiki
engine to run. While I am wadeing thru the masses of them, and trying a
few promising candidates, I have a few requests.

Does anyone here know of any wiki engines that support:
password protected pages,
class-based-apperence [this "class" of pages looks like so,
                       this other "class" looks so...],
wysiwyg editing with tables and other advanced features,

[ordered by need/want]

Baring the above requests, if it is good and open source I would still
like to hear about it, I can always try to implement those things on my
own.
