Failed to render math exp from latex code

[Hzzone]

Firstly thanks for your great work that helps a lot! Here I find it fails to convert the latex math code into a table, the test code is below:

\begin{table}
\centering
\begin{tabular}{lll} 
\toprule
$a^+$ & 2 & 3  \\ \cmidrule(lr){1-3}
4 & 5 & 6  \\
7 & 8 & 9  \\
\bottomrule
\end{tabular}
\end{table}

In my opinion, it is somewhat convenient since there usually appears math code in the table.

This is expected behaviour.
