Here is an XML sample and some of the e-i-c's we've used. Turns out it
wasn't cell padding ... it was futzing with the offset. I think. Again,
this is old ... we used it until tables started supporting the rotate
attribute and I stripped most of it out. I think I still support the
<rotate> element somewhere but I'm not sure anyone uses it anymore.
<entry align="center" valign="bottom">
<para>!,%\hbox{\special{pub: rotate 90}%,<rotated_impact_cell.fmt>,\Key
Lime Pie\,</rotated_impact_cell.fmt>,%}%,!</para>
</entry>
<e-i-c gi="rotate">
<charlist inherit="1" charsubsetref="suppress">
<usetext source="%\hbox{\special{pub:" rotate<br="/>90}%,<rotated_cell.fmt>,#CONTENT,</rotated_cell.fmt>,%}%">
<subchars></subchars>
</usetext>
</charlist>
</e-i-c>
<e-i-c gi="rotated_cell.fmt">
