Notes on how to read tables with Emacspeak 8.0 and W3 4.0 beta

["T. V. Raman" <raman@xxxxxxxxxxx>]

Thanks for posting the summary.
An update on what is happening with tables.

We discovered that a large number of tables generated by
wysiwyg html editors were bombing inside emacspeak because
they all produce an octal 225 for a bullet --it's a single
character that takes 4 spaces when displayed.
This meant that when we computed the column alignment in the
emacspeak extension things got computed wrong.

Thierry.Emery@xxxxxxxxxxx
who helped me write the table structure code wrote a patch
for this that I am testing and it appears to work-- but I
also seem to have broken 
the code I wrote for handling nested tables (not yet
released).

Anyway, html tables are an unholy mess --given the hacks
that the commercial browser vendors have snuck in, it turns
out that each table cell in its ultimate glory (or may be it
should be gory) is an HTML page in its own right for
purposes of rendering
--and that's how the various wysiwyg editors are emitting
them.
