Is there any way to add the “tabular” environment to the LaTeX support for this site?

Question

That would allow this structure, instead of trying to build tables with ASCII or UTF-8 characters, tedious to say the least.

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

The chosen answer below uses the following code, which works for non-numeric cell values as well.

\begin{array} \\
  a & b & c \\
  4 & 5 & 6 \\
  7 & 8 & 9 \\
\end{array}

\begin{array} \\ a & b & c \\ 4 & 5 & 6 \\ 7 & 8 & 9 \\ \end{array}

Answer 1

MathJax does not implement tabular. One can use array instead: \begin{array}{ l c r } 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \\ \end{array}

But I usually prefer text to table tool by Senseful, to avoid relying on JavaScript for rendering.
