latextabular

using Latexify
copy_to_clipboard(true)
arr = ["x/y" :(y^n); 1.0 :(alpha(x))]
latextabular(arr) |> println

outputs:

\begin{tabular}{cc}
$\frac{x}{y}$ & $y^{n}$\\
$1.0$ & $\alpha\left( x \right)$\\
\end{tabular}

Unfortunately, this does not render nicely in Markdown. But you get the point.

latextabular takes two keywords, one for changing the adjustment of the columns (centered by default), and one for transposing the whole thing.

latextabular(arr; adjustment=:l, transpose=true) |> println

\begin{tabular}{ll}
$\frac{x}{y}$ & $1.0$\\
$y^{n}$ & $\alpha\left( x \right)$\\
\end{tabular}
