Try your HTML using the Duxbury NISO//DAISY importer rather than the 
SGML/ICADD (HTML) importer.  There are more than 120 styles, corresponding 
to the elements of the DTBook file format.  These styles still need to be 
used by more people and systematized, but you start from a richer set of 
styles and are closer to conformance with braille conventions and 
readability.  In particular, table and list elements are supported.

I don't have a working DBTW in front of me; you might need to create a NISO 
template first.
