Thread:Talk:Requests for comment/Abstract table definitions/Insert a table

In the Edit Page there is button for inserting a table, as in addvanced just above. I'm looking for the file in which it is defined, and where is it's icon located? I looked in the HTML page and the address is: src="http://upload.wikimedia.org/wikipedia/he/6/60/Button_insert_table.png" (and for some reason it isn't found). Where as all other buttons address is located in the Skins file: src="/skins/common/images/button_nowiki.png". So I'd like to change the address to the file Skins as all other buttons. Can anyone help?
