That was the idea behind adding better support for at least some kinds of
tables in 2.8.3.  And I tried to do it in a way that, I hope, won't get
in the way of any later, more complex, fuller table support.

Well, lynx has had *some* form of support for tables for a long time.
Maybe you could use the terms I used in

Lynx's Minimal Table Support = treat <TD> as ' ', treat <TR> as <BR>
(more or less).  That's in general (for "real" tables) much better than
your minimal proposal.

Btw you may want to read
   Linkname: TABLEs on non-TABLE Browsers

if you haven't come across it already.  Think about how the example(s)
would look if
 (a) lynx had absolutely *no* table support, or
 (b) if your minimal approach was implemented.

Lynx doesn't anything with CLEAR attributes on BR.

I get the impression you are only thinking about "non-simple" tables (in
terms of the mentioned README.TRST), i.e. table cells containing whole
paragraphs & other blocks of text, and forget about the most simple "real"

When tables are used just for positioning and layout, I generally don't
miss seeing them.  Mostly only if some text mentions something silly like
"click the blahblah icon to the left" etc.

I hope your new shell account will give you a chance to see 2.8.3 in
action soon. :)

Btw, I came across an example that shows how the TRST code (i.e., 2.8.3)
handles even some rather complex "simple" tables quite nicely:

   Linkname: Al's tricky table

The second, "here's what we came up with", is shown with all the alignments
right, it seems.  (There are some glitches when in TagSoup mode - not too

Well, not exactly.

Adding horizontal scrolling should be much simpler than any of the
complex table ideas.
