More table tricks: Collapsible Tables with DOM

Working with Mint I was missing an option to collapse the different panes when I don’t want to read them. Some hacking later, I wrote a script that automatically allows you to collapse and expand a table by activating its footer. As a visual indicator, the script adds an image to the footer (this also allows keyboard access). It is a work in progress and I need your help to fix it for Opera and get rid of a weird Firefox issue. See the collapsible tables demo
