The macros in question produce a fatal error while \hline compiles correctly.
Can this be corrected or should I replace all \*rule with \hline?

Here is a minimal example:

%--8<-------------------------------------
\documentclass[10pt,a4paper]{memoir}
\RequirePackage[italian]{babel}

\begin{document}

\begin{tabular}{cc}
\toprule
Valore per difetto di \(\sqrt{2}\) &Valore per eccesso di \(\sqrt{2}\) \\
\midrule
1 & 2\\
1,4 & 1,5 \\
1,41 & 1,42\\
1,414 & 1,415\\
1,4142 & 1,4143\\
\ldots & \ldots\\
\bottomrule
\end{tabular}

\end{document}
%--8<-------------------------------------

Compiled with:
make4ht toprule.tex -c ml_make4ht -l -u -s -d ./html/mathjax "mathjax, 3, sec-filename, fn-in, blind"

Thank you for your attention.

Thanks for the report. It seems that Memoir's support for the Booktabs package changed, so TeX4ht clashes with it. Try this configuration file, memoir.4ht, it should fix it:

Thank you, it works perfectly!

If you can, I would ask one more thing:

during compilation I get these warning messages:

[WARNING] tocid: char-def module not found
[WARNING] tocid: cannot fix section id's
[...]
[WARNING] domfilter: DOM parsing of ml01InsiemiNumerici.html failed:
[WARNING] domfilter: .../texlive/texmf-dist/tex/luatex/luaxml/luaxml-mod-xml.lua:175: Unbalanced Tag (/p) [char=14719]

Is there an easy way to avoid them and get a clean compilation?

The command I use is:

make4ht ml01InsiemiNumerici.tex -c ml_make4ht -l -u -s -d ./html/mathjax "mathjax, 3, sec-filename, fn-in, blind"

and configuration file is as follows:

Thank you anyway for your work and the great expertise you make available to those who need to convert LaTeX to html.

The missing char-def warning can be fixed by installing ConTeXt.

Regarding the DOM error, do you experience it on this sample file? I can compile it without any errors with your configuration file.

The warning:

[WARNING] domfilter: .../texlive/texmf-dist/tex/luatex/luaxml/luaxml-mod-xml.lua:175: Unbalanced Tag (/p) [char=4871]

Appears only once even if there are multiple calls.

Thank you for your helpfulness.

There seems to be two issues. First is that the wrong Pgf driver for SVG is used, which leads to some non-HTML tags in the document, second is that one of the boxes isn't started correctly, so it gets no frame.

The first issue can be fixed by adding this line to your TeX file, before \usepackage{tcolorbox}:

 \def\pgfsysdriver{pgfsys-dvisvgm4ht.def}%

The second can be fixed using this version of tcolorbox.4ht:

I've added both of these fixes to TeX4ht sources, so you can also just wait few days and they should be included in TeX Live.

I have made the two changes you propose, but I still get the same warning message (:-?).

Ah, I see, I didn't use the exact same options as you. I can reproduce this when I use them. Try this version of tcolorbox.4ht:
