tex4ht for some reasons added extra horizontal lines above and below each table
. While these lines do not show in pdf.
Here is a MWE
\documentclass[11pt]{article}%
\usepackage{float}
\begin{document}
This is my table
\begin{table}[H]
\centering
\begin{tabular}[c]{|c|c|}\hline
A & B \\\hline
853.075 (sec) & 43.711 (sec)\\\hline
14.218 (minutes) & 0.729 (minutes)\\\hline
\end{tabular}
\end{table}
my table is done
\end{document}
Compiled using lualatex
gives
But compiled using make4ht foo.tex "htm"
gives extra horizontal lines above and below the table, which I did not ask for
