This left-hand column is wide enough to add any content you
wish to keep separate from the main area, or be especially
noticeable.
You can replace the demo buttons with the ones appropriate
to your site (choose from 25 useful titles in the zip/sit
files, or create your own with the blanks included.)
If you add other images, be aware that if they are wider
than the table itself (140 pixels) the right-hand side main
table will get narrower.
