Current version of fetch breaks on 2-column code examples in wikibooks

[PyllrNL]

Hello,

I'm currently working on fixing some errors on ada-lang.io and noticed that errors originated from the wikibook
source. This has since been rectified. However, the current version of aqs2mdx breaks on the tables in 2 column
code examples in wikibooks.

I would love to fix the issue, but have some questions before I can implement anything:

The comment on line 98 says: "flatting tables because no multiline tables in .md". What is meant by this?
Currently the code removes the Attr, [ColSpec], and Tablehead of the JSON and removes the outer array
of the [TableBody]. Which results in an incorrect JSON file.

I would love some explanation of what needs to happen, or maybe a hint which tables in the wikibooks source requires
this codepath.

"flatting tables because no multiline tables in .md"

I mean, in Markdown you can't write in a cell of the table any content that doesn't fit one line, like

| The long text  | Other |
| that starts in | cell  |
| one line and   |       |
| continues.     |       |

Here you get a table of 4 rows and two columns, not one row and two columns as you may require. So, you can't put a code block in a table cell in Markdown, for example.

I've tested some more, and the tables in the wikibooks are translated by pandoc as follows:

<table>
  <tr>
    <td><pre><code>
      # Code example
    </code></pre></td>
    <td><pre><code>
      # Code example
    </code></pre></td>
  </tr>
</table>

So we can either find a way to make the syntax highlighting of MDX work with a code tag or we can extract
the code samples and place them between <div>'s and style the <div>'s to be multi column, like:

<div class="Multi-Column">
  <div class="Multi-Column-Child Left">
    ```ada
      Code Example
    ```
  </div>
  <div class="Multi-Column-Child Right">
    ```ada
      Code Example
    ```
  </div>
</div>

I would personally like the second form, since there are more styling options, but I would like your take one this

Can you try pandoc-2.9.2.1?

When I wrote the aqs2mdx filter, I was using Ubuntu 22.04, where pandoc-2.9.2.1 was most likely installed. This version of pandoc uses pandoc-types-1.20, whereas the current version in Ubuntu 24.04 is pandoc-3.1.3 pandoc-types-1.23. The table definitions in these versions are different, which causes the error.

x	1	2	3	4	5	6
Table	[Inline]	[Alignment]	[Double]	[TableCell]	[[TableCell]]
Table	Attr	Caption	[ColSpec]	TableHead	[TableBody]	TableFoot

• pandoc-types-1.23.1
• pandoc-types-1.20

I'm not experienced with MDX od HTML development. I'm fine with div approach.
