Thanks for your suggestion.  I may end up needing to know how to configure
the tabular environment.

Last night I ran across a reference to using a configuration file
specifying pic-tabular and I believe that this will take care of my needs
pretty well.  I can have all my tables be images and produce a nice looking
ebook.  It would be nicer to have an HTML table so that increasing the font
size would make the table text larger, but I am happy enough to have a
workable solution.

I also have modified /etc/tex4ht/tex4ht.env to make the images a little
larger (-x 1800) and darker (--gamma 1.5).  With these changes I have
tables and math which look much better on the Kindle.  Before the math
images were a light gray and hard to read.  Now they look pretty crisp.
