Reproducer: save this sample HTML to a file and view it with eww:
-----8<-----8<-----
<html>
<body>
<table>
<tr><td rowspan="3">text along left side of table</td></tr>
<tr><td>row 1</td></tr>
<tr><td>row 2</td></tr>
</table>
</body>
</html>
----->8----->8-----
I'm not terribly concerned about the exact formatting of the table, but
I do expect to see the "row 1" and "row 2" text somewhere. Instead, all
I see is
-----8<-----8<-----
text along left side of table
----->8----->8-----
The test case is abstracted from some HTML-only notification emails that
I have started receiving. With the "row 1" and "row 2" text missing,
the emails are close to useless.
I can't tell if I should expect shr to handle rowspan correctly. (Is
there somewhere that documents known restrictions on the HTML that shr
can handle?) If I shouldn't expect rowspan to be handled correctly (I
can imagine it's hard to get right), please treat this as a wishlist
(feature request) report.
I have verified that the problem also occurs with 26.1 and 26.3, and
I've reproduced it with "emacs -Q".

Yeah, I can reproduce this, and I see what the problem is. The way shr
computes rowspan layouts is by adding "dummy" TD elements in the rows
that the spanning element should cover, but this messes up the
calculation of how many columns there really are. So it's basically a
off-by-one error, but I'm not quite sure what the best way to fix this
is...

This is now fixed in Emacs 28.1.
Eli, I think the fix should be safe for Emacs 27.1, too, but I've been
out of the loop and I'm not sure what the status is at the moment. This
isn't exactly a critical bug -- rowspan isn't used that much these days,
and it's a very old bug.
On the other hand, I think it's a pretty safe fix to add, so should I
cherry-pick it for Emacs 27.1?

The above generally translates into "don't put this on emacs-27". But
maybe if you tell more details about how it is safe, I will change my
mind about this.
Thanks.

So does this mean that Emacs 27 is in the "critical bug fixes only"
state?
This is certainly not a critical bug (or a regression), so I'm not
backporting the fix, then.

I hope to have RC1 soon. So yes.

Thanks!
I applied 510da73b4a to my copy of 27.0.91, and it works there, too. (I
understand about it being too late for 27.1. I just wanted to note it
in the bug report in case someone else hits this issue and wants to
manually apply the fix.)
cheers,
mike
