I had sent a mail to Tom (address@hidden) but I got no answer.
I'll send him again from now.

I've never asked Subir to add a link. There are two reasons.
One is I think few people are interested in my scrips because
no one response my first announcement.
Another is I have almost only Japanese documents.
I'll ask him after writing a little more documents in English.

I tried and found it works fine. Thanks.

I fixed it by converting &nbsp; to space.

You are right! Please forget what I wrote.

I saw your code but havn't tried yet. I think it's great and works fine.

Yes and I've tried. Please try this.

    http://www.t3.rim.or.jp/~patakuti/tmp/t2thtml

I added two new options: "usepre" and "usetable".
"usepre" means convert tables to preformatted text as old one does.
"usetable" means convert tables to tables as you wrote
(which is fitted for TRST support Lynx)

I tried this way. I think the output is GREAT!
    % t2thtml usetable ocaa.html > foo.html
    % lynx -dump -width=200 foo.html > foo.out

Can I get immortal fame?
