How to get *Collapsible tables* on wiki?

Greetings everyone, Glad to meet you here. I have a question about wiki syntax. I wanna have some Collapsible tables on my wiki pages, like http://en.wikipedia.org/wiki/Help:Collapsing But when I use the same example code as it suggested, it doesn't work on fedora wiki page, since the following js file is needed: http://en.wikipedia.org/wiki/MediaWiki:Common.js So I want to know if it is possible and allowable to have fedora wiki run this js? If yes, how to load this file? If no, is there any other way to have Collapsible tables on fedora wiki?
