I already posted an css example for formating the table and I hope this helps.

The images used are the same that are used if you sort your thread list - so you should think about changing your style if they don't match. It is also possible to change the product. Edit sortable.js and around line 108 you find

if (span.getAttribute("sortdir") == 'down') {
	ARROW = '&nbsp;<img src="' + IMGDIR_BUTTON + '/sortasc.gif" />';
	newRows.reverse();
	span.setAttribute('sortdir','up');
} else {
	ARROW = '&nbsp;<img src="' + IMGDIR_BUTTON + '/sortdesc.gif" />';
	span.setAttribute('sortdir','down');
}

Edit both bold filenames to use other images. It can be that you will have to clear your browsercache that you can see the changes.
