Hello Micahl; An update.
Thanks, your fix did fix the vertical lines on tabular that went missing
after 118 subsections.
Now they show in all sections.
But I am afraid a new problem shows up. Now verical lines on
longtable no long show up. I am not sure why.
Here is a MWE (I attached all these in zip file in case of line wraping)
==================
\documentclass[12pt]{article}
\usepackage{longtable}
\begin{document}
\begin{tabular}[c]{|l|l|l|l|l|l|l|l|l|}\hline
1&1. (1)&3.9 (50)&16.6 (114)&3.8 (169)&4. (45)&7.5 (169)&4.2 (164)&42.4 (169)\\
2&7.3 (21)&5. (20)&3.6 (17)&1.9 (4)&14.3 (13)&16.8 (5)&4.6 (2)&3.3 (26)\\
4&6.4 (5)&14.3 (13)&40.7 (46)&16.6 (43)&5.5 (43)&4.8 (40)&5.3 (1)&6.9
(4)\\\hline
\end{tabular}
\begin{longtable}[c]{|l|l|l|l|l|l|l|l|l|}\hline
1&1. (1)&3.9 (50)&16.6 (114)&3.8 (169)&4. (45)&7.5 (169)&4.2 (164)&42.4 (169)\\
2&7.3 (21)&5. (20)&3.6 (17)&1.9 (4)&14.3 (13)&16.8 (5)&4.6 (2)&3.3 (26)\\
4&6.4 (5)&14.3 (13)&40.7 (46)&16.6 (43)&5.5 (43)&4.8 (40)&5.3 (1)&6.9
(4)\\\hline
\end{longtable}
\end{document}
===============================
When compiling the above using
make4ht -c ./nma_mathjax.cfg vborder.tex "mathjax,htm"
Then vertical lines in longtable are missing in HTML. But when compiling using
make4ht vborder.tex "mathjax,htm"
Then vertical lines in longtable do show up. In both cases
the vertical line in tabular show up OK.
the .cfg above is what you send.
It seems the fix had some side interaction with longtable?
Please see attached zip file with the source code and .cfg and HTML generated

Thanks for your help
