feat: Support specifying terminal width

Discussed in #33

^{Originally posted by NikosAlexandris January 26, 2024}
Rich table output in the console is truncated (i.e. table column names are incomplete), for example : https://nikosalexandris.github.io/rekx/how_to/inspect/. See in this pages source code the output of commands wrapped inside a block

    ``` bash exec="true" result="ansi" source="above"
    ```

Any idea how to "fix" this ?

We could provide a new option to set the terminal width in the subprocess. Basically export COLUMNS=1000.

@NikosAlexandris could try the following and let me know if it fixes your issue?

``` bash exec="true" result="ansi" source="above"
export COLUMNS=1000  # markdown-exec: hide
rekx inspect data/single_file/SISin202001010000004231000101MA.nc
```

Yes! It works.

In the screenshot, above is without export COLUMNS=1000 and below is with it :

That looks so much better! Had we also a full-width option, it'd be ideal. Kind regards @pawamoy.

Can such an option (here export COLUMNS=1000) be pre-set globally ?

Thanks for reporting back 🙂

Good idea, I'll think about it 🤔

What do you mean exactly by full-width option?

Please have a look at https://jupyterbook.org/en/stable/content/layout.html#full-width-code-cells.

I see, thanks. This is irrelevant to Markdown Exec though, as it's not responsible for the actual (HTML) rendering of code blocks.
