# Failing to render LaTeX tables using tabular environment

I have troubles to get tables rendered withing Latex “block”. All I do is insert this

$$\begin{tabular}{ l c r } 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \\ \end{tabular}$$

and it just fails to render. As if the LaTeX used by Logseq does not recognize this tabular environment. Unless I am wrong, the environment is defined in basic LaTeX, no extra package is needed.
