Markdown tables ignore alignment

[ThorpeJosh]

Describe the bug

context When I create a table in markdown

expectation I expected the alignment to render according to the markdown syntax for table alignment.

bug But instead all cell or column alignment is always left, despite specifying center or right

example

Jupyterbook docs Here the markdown syntax says the table should have the Validation column aligned right, as it is rendered here in Github below,

Training	Validation
0	5
13720	2744

however the jupyterbooks render as shown in the link above is aligned left.

Reproduce the bug

1. Go to Jupyterbook docs and copy the example table markdown code.
2. Paste the markdown in a markdown file and render it in a jupyterbook, with default theme/settings.

List your environment

Jupyter Book : 0.12.2 External ToC : 0.2.4 MyST-Parser : 0.15.2 MyST-NB : 0.13.2 Sphinx Book Theme : 0.1.10 Jupyter-Cache : 0.4.3 NbClient : 0.5.11

Heya this will be fixed once jupyter-book is updated to myst-parser 0.16: https://myst-parser.readthedocs.io/en/latest/develop/_changelog.html#improvements-to-table-rendering

@chrisjsewell should this wait for the current myst-nb work to be released?

https://github.com/executablebooks/MyST-NB/pull/380

Or do you think it is worth tagging an intermediate release of myst-nb to move myst-parser from 0.15.2 to 0.16.1

@chrisjsewell , I am new to Jupyterbook and also experience the same problem with all tables being left aligned instead of right (which I want for numeric columns). Any news on this issue? Here is my system info

$ jb --version
Jupyter Book      : 0.15.1
External ToC      : 0.3.1
MyST-Parser       : 0.18.1
MyST-NB           : 0.17.2
Sphinx Book Theme : 1.0.1
Jupyter-Cache     : 0.6.1
NbClient          : 0.7.3

I simply use this command jupyter-book build UvA-ACOI and use the default _config.yml

Thanks!
