For the height of the phone, you can reduce it by reducing the width of the image. You can do this by replacing whatever is currently defining the image with replacing ImageName.ext with the image name. Then just tinker with the number of pixels until the preview shows the mobile icon to be the same height as the Facebook icon.

For the table collapsing, the reason it can't happen with this table is because you have no header row (a row started by a ! instead of a |), and the collapsing code searches for the header row to put the show/hide on and, well, not hide that row when the rest of the table is hidden. Also, I can't really tell from your comment exactly what you wanted to collapse, but nothing can collapse without a header row.

And just one more point I would like to mention: For what you call a fluid table (not actually a fluid table, which is a table that's width changes "fluidly" as the parent element, in this case the content area of the Wikia page, expands and collapses) would require placement in an area that because of Wikia's fluid layout will cause problems on some devices. I can't think of anywhere you could put the fixed position table where it won't overlap content at the smallest browser widths where even the right column disappears down to the bottom of the pages, and I have heard Wikia complain on another wiki about putting content over the background image because it interferes with their ads (see here for a link to the conversation). If you were to use a fixed position table, where would you put it so that it would always work and not interfere with Wikia's ToU?
