Andy,

   What the heck, just made it self-contained.

   If I use the enum, table is centered. If I use the string, it's left
aligned. Must be me.

   Can I adjust the vertical position of the table on the page?

   I assume that for adjusting the spacing of the rows I change the leading
in the table style.

   When I get this properly positioned, I'll have more text to add, plus
another table, and a small black box that will fill in one of the OMR
bubbles. That's why I want to learn how to precisely position everything on
the page.

   I greatly appreciate your help, and that of everyone else. Stepping back
and starting from scratch worked much better for me than did trying to fit
my report in a pre-existing example.

Rich
