specify latex table package

[jgunstone]

Which area is this feature request for?

LaTeX Export

Describe the feature you'd like to request

i'd like to be able to specify what latex table package to export with.

based on this: https://github.com/executablebooks/mystjs/blob/ef07d85f49f84f575e2917437f333db6aacacfad/packages/myst-to-tex/src/tables.ts#L162-L194

it looks like the tabular package is hard-coded in?

Describe the solution you'd like

I'd like to use either:

• longtable (as i have a requirement for multipage tables)
• tabularray (newer and in my humble opinion better, its great and has excellent customisation features, including multpage and multicol support)

The example below is produced using tabularray. To my understanding it would be impossible to do this using either tabular or longtable test2_1.pdf

\documentclass[twocolumn]{article} \usepackage[margin=15mm]{geometry} \usepackage{tabularray} \usepackage[sfdefault,lf]{carlito} %% The 'lf' option for lining figures %% The 'sfdefault' option to make the base font sans serif \usepackage[T1]{fontenc} \renewcommand*\oldstylenums[1]{\carlitoOsF #1} \begin{document} Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text.

I am also looking at using longtable and tabularray because with the current table package that is used, tabular, the rows don't go nicely onto the next page.

It would be great to add support for these

There is already some support for longtable in the myst-to-tex subpackage (here), however I don't think that the options are exposed to the directive level in mystmd cc @fwkoch ?
