longtable bug cause overflow

longtable bug description

• https://www.latex-project.org/cgi-bin/ltxbugs2html.new?pr=tools/3512
• longtable with float ends up rendering past end of page latex3/latex2e#137

there are some bugfix:

• https://tex.stackexchange.com/questions/324227/pagebreak-doesnt-work-with-floats-and-longtabu.
• https://gist.github.com/muzimuzhi/ba7fab51f235b8a59af9461e0c5e05ac
  But not Completely repaired. See mwe below

So, can pandoc not use longtable by default? May be able to add a property, manually specify longtable:

left  right
---  -----
a     b

: Title {.long}

when use {.long}, generate longtable. otherwise use booktabs

MWE

\documentclass{article}
\usepackage{longtable}

% helper pkg
\usepackage[pass, showframe]{geometry}
\usepackage{lipsum}
\usepackage{listings}

\begin{document}
\begin{lstlisting}[float=htbp]
hello
\end{lstlisting}

\begin{figure}[t]
  a\\b\\c\\d
\end{figure}
\begin{lstlisting}[float=htbp]
hello2
\end{lstlisting}

\lipsum[1] % optional
\begin{lstlisting}[float=htbp]
hello3
\end{lstlisting}

\begin{longtable}{l}
  cell
\end{longtable}
\begin{lstlisting}[float=htbp]
hello4
\end{lstlisting}

\lipsum
\end{document}

Pandoc does use longtable by default. I have occasionally seen awkward layout relating to this bug. My own solution was just to patch longtable.sty as indicated, and I haven't seen the issue since then.

There's already an issue for adding configurable support for other table formats, #1023.
So I think this issue should be closed in favor of that one. (You may want to add this information to that issue.)

This issue is pretty old but I think the longtable environment hasn't yet been completely fixed, despite the patch given by: https://www.latex-project.org/cgi-bin/ltxbugs2html?pr=tools/3512

For those who don't need longtable but a quick fix to make markdown tables usable with floats, I suggest a patch on the pandoc latex writer itself (in src/Text/Pandoc/Writers/LaTeX.hs):

781c781
<                         return ("\\toprule" $$ contents $$ "\\midrule")
---
>                         return ("\\hline" $$ contents $$ "\\hline")
788c788
<               then return "\\toprule"
---
>               then return "\\hline"
800,804c800,802
<   return $ "\\begin{longtable}[]" <>
<               braces ("@{}" <> colDescriptors <> "@{}")
<               -- the @{} removes extra space at beginning and end
<          $$ capt
<          $$ firsthead
---
>   return $ "\\begin{table}[]"
>          $$ "\\centering"
>          $$ "\\begin{tabular}" <> braces (colDescriptors)
806d803
<          $$ "\\endhead"
808,809c805,808
<          $$ "\\bottomrule"
<          $$ "\\end{longtable}"
---
>          $$ "\\hline"
>          $$ "\\end{tabular}"
>          $$ capt
>          $$ "\\end{table}"

It works with pandoc-2.5 and switches the default table environment to table and tabular. I think it is sane providing a simple table environment as default and more advanced ones in command line options. But the discussion better be done in #1023.

@cykerway My solution is to use lua filter, use tabu replace longtable. Ref: https://github.com/annProg/PanBook/blob/master/extensions/tabu/tabu.lua

Any progress on this? I tried using the patch from here, but to no avail, the figures I insert after the table go completely off-page, so for now I'm forced to manually change all instances of longtable to a tabular inside of a table (tedious), or making the whole document half-empty by spamming \pagebreak after each \end{longtable} to ensure figures aren't mangled.
I assume that #4392 could fix the problem, but it doesn't seem to have had much activity for quite some time now...

I haven't seen the issue since patching longtable.sty locally.
Maybe you could post an example that we could try to reproduce.

[jolars]

This seems to have been finally solved (latex3/latex2e#137)! So I guess we just have to wait for texlive 2022.

[ibutra]

@jgm I tried every patch I found and every version of longtable.sty I found online but the problem persists for me. As we still need to wait for the updated texlive until planned April. Can you tell me which patch you applied or attach your longtable.sty here?
