Add support for the table code.

I was using LaTeX workshop in VSCode to write documents, and the latexindent it uses by default works great, but it's too slow. I saw that the latest version of LaTeX workshop supports tex-fmt. after learning how fast it is, I immediately tried it. But unfortunately it doesn't seem to handle table code very well. However latexindent aligns all the & very well.

I directly use the binary file of tex-fmt.
What is the purpose of this C compiler of yours?

I could be interested in adding support for aligning ampersands in tables. However some thought would have to be put in to the implementation.

Just wanted to chime in and mention that this probably the biggest thing I'm missing right now with this formatter. Latexindent is extremely convenient with how it aligns all the &'s in the table and I find myself having to constantly switch back and forth to make use of missing features like this one. Hope to see it eventually implemented!

Some input regarding proper implementation: One "edge case" not handled well by latexindent (if used as reference behaviour) is double backslashes \\ in the table, which are not row-terminators. E.g. when using \makecell from the makecell package.

Here's a reference to the implementation in unified-latex if it helps: https://github.com/siefkenj/unified-latex/blob/main/packages/unified-latex-prettier/libs/printer/environment.ts#L148
