To reproduce the issue, use pandoc (e.g., via https://pandoc.org/try/) to convert the following tex file to html:

\documentclass{article}

\begin{document}

\begin{equation}
  [0,1)
\end{equation}

\begin{table}[h]
\end{table}

\end{document}

This yields the error:

unexpected end of input
expecting \end{equation}

I've checked that the half open/closed paren/bracket as well as the "[h]" argument for the table environment are necessary (the error goes away if these features are omitted), but have not tried further variations. A work-around is to use "\left[ ... \right)".
