Lynx and multi-level tables

Kenny is correct.

By the time we had W3C specs on tables, lynx development was pretty
moribund. Considering this, I find it quite amazing how effective lynx
still is in so many circumstances, but proper access to semantec tabular
data isn't something it provides. Now, I do think it does a superior job
of rendering the use of tables for layout--but that's not what you asked
about.

I will confess that I do not use Lynx as my primary browser, so I am unfamiliar with its behavior with more complex, but properly coded, tables.  I also don't have any sample tables to cite.
