pandoc 2.7.3:


[0] Are grid tables the most powerful of the choices of tables?  Does it 
expose all features, or are there some others that require using a 
different table input format?


[1] there is an odd feature that I have run into.

```
+-------------+----------+--------------+
|  Event      |  Prob    |  All-Equity  |
+=============+==========+==============+
| Rain        |   1/4    |     $60      |
+-------------+----------+--------------+
| Sun         |   3/4    |     $100     |
+-------------+----------+--------------+
```

colors the right cells in background gray when typeset in LaTeX.  could 
someone please tell me what the rules are for this effect?  are there other 
interesting effects?


[2] Is there a way to get a horizontal line into the middle of a table, not 
just in its use as the table header separator?  (put differently, can one 
enter a \midrule)

[3] I accidentally once triggered something that created an \fbox{} like 
effect.  alas, I can't reproduce it now.  which feature is this?



help appreciated. /iaw


PS: I also just tried table.el mode as recommended in the pandoc guide.  I 
think it is from 2001, and no longer works.  after specifying my table 
parameters, emacs tells me that it is a wrong symbol type or something like 
this.  is there a better emacs mode?

PS: Is there any progress on multi-column headers?

table.el is part of Emacs, so it should work. If not, `M-x 
report-emacs-bug'.

That being said, you can also use orgtbl-mode, which gives you 
Org-style tables in non-Org buffers. I'm not sure if Org tables 
support all of Pandoc's table features, however. And, the other 
way around, I'm pretty sure Pandoc does *not* support all features 
of Org tables. So you kinda lose something on both sides, but the 
features that you do have may just be enough. The main advantage 
is that table creation and handling is much easier in orgtbl-mode 
than with table.el.

thanks, joost.  good answer to my PS note.  alas, I still need the other 
aspects.  on the PS note:

on my macos emacs, I see a built-in table-wixed-width-mode , but not a 
table mode.  is this what you mean by built-in?  I also looked at the elpa 
archive, but did not see a table mode in it, either.

the bug is then in the pandoc documentation, because it still points to 
something from 2001, which I loaded and found to no longer work on a recent 
emacs.  it should probably just be removed then, perhaps replaced by your 
post.

Yes, sorry, I cannot help with that. :-(

Despite what the Pandoc manual says, it's not actually a mode, 
that's probably why you're not finding it. You can insert a table 
with `table-insert`. For further details, you can check out the 
Emacs manual (`C-h i m Emacs RET m Text Based Tables RET` or 
online at 
<https://www.gnu.org/software/emacs/manual/html_node/emacs/Text-Based-Tables.html#Text-Based-Tables>).

Yeah, the Pandoc documentation probably shouldn't call it a 
"mode". "Table package" seems better, it's what's used in the 
Emacs documentation. And a link to the official documentation 
would probably be better.

Yes it has all the features.

I can't reproduce this...nor can I think of any reason why you'd
be seeing this effect. Certainly nothing on pandoc's side.

No.

No idea.

We should update the docs about entering tables in emacs.

thank you, john.

I think the gray typesetting originated in my redefinition of the verbatim 
environment which colors the background gray for them.

I believe pandoc sees "$60" and decides to set it in a verbatim environment 
(because of the \$).  It does not do this for other cells, because there is 
no special character.

No, it has nothing to do with the $.  It's because the contents
of the cells are parsed as Markdown.  In these cells you have a
4-space indent, so these are parsed as indented code blocks.
