I am trying to compile very old code (bit convoluted) but compiles OK with
lualatex but gives compile error with tex4ht.
----------------------------
\documentclass[10pt]{article}%
\begin{document}
\begin{tabular}{|l|}\hline
\begin{tabular}[c]{l}
$i\in C(J)$\\
$j\in C(J)$
\end{tabular}
\\\hline
$%
\begin{tabular}[c]{l}
$i\in C(J)$\\
$j\notin C(J)$
\end{tabular}
$ \\\hline
\end{tabular}
\end{document}
--------------------
lualatex gives this PDF
enter image description here
But
make4ht -ulm default -a debug HW1.tex 'mathjax,htm'
Gives
---------------------------
(/usr/local/texlive/2025/texmf-dist/tex/latex/l3backend/l3backend-dvips.def)
(./HW1.aux) (/usr/local/texlive/2025/texmf-dist/tex/latex/lm/t1lmtt.fd)
! Missing $ inserted.
<inserted text>
$
l.15 $j\notin
C(J)$
?
-----------------
Why it fails with tex4ht but not with lualtex? Is this a bug?
The problem goes away when removing the $ around the second row. i.e. this
compiles OK now with tex4ht
--------------------------
\begin{document}
\begin{tabular}{|l|}\hline
\begin{tabular}[c]{l}
$i\in C(J)$\\
$j\in C(J)$
\end{tabular}
\\\hline
\begin{tabular}[c]{l}
$i\in C(J)$\\
$j\notin C(J)$
\end{tabular}
\\\hline
\end{tabular}
\end{document}
