I am helping a friend with a Wikia site he created and some of the content is going to be in a table. With the size of the table I thought it would be best to make a filterable table instead of just a sortable table.

I found some code online on how to create it, however it says I will have to edit mediawiki:common.js. I have searched the site and I couldn't find how to access it anywhere. How would I go about finding the the page to make the edits?

I do have admin access to the wikia page in question.
