I use a modified on my site, but the table for display a ticket sets the bgcolor rather than relying on css.  I'd submit a patch, but this ticket system doesn't have that, so here's what needs to change:

<ol>
<li>In tktsetup_.c remove all bgcolor="#d0d0d0" text.</li>
<li>In style_.c add CSS to style the td tags (although they look find without it).</li>
</ol>

Additionally, these strings in the .c files could easily just be text files that are injected into sqlite.  Not sure what the purpose is of putting them in there.
