Markdown Table (still) breaks eisvogel

Markdown Tables above a certain width seem to break the "tex -> pdf" step with any engine.

Some error message like "that markdown table is gonna end up wider than the page (so eisvogel is just gonna go up in flames)" would be helpful.

Tested with pdflatex and xelatex, pandoc 3.8.3, eisvogel 3.3.0;

## Examples

### 4 vs. 5 Columns (max width 54 characters)

```md
| A / B  | P      | Cluster | d(A, P)               | d(B, P)               |
|--------|--------|---------|-----------------------|-----------------------|
| (2, 3) | (1, 5) | A       | abs(2-1)+abs(3-5) = 3 | abs(6-1)+abs(3-5) = 7 |
|        | (2, 3) | A       | 0                     | abs(6-2)+abs(3-3) = 4 |
|        | (2, 7) | A       | abs(2-2)+abs(3-7) = 4 | abs(6-2)+abs(3-7) = 8 |
|        | (3, 6) | A       | abs(2-3)+abs(3-6) = 4 | abs(6-3)+abs(3-6) = 6 |
|        | (5, 1) | B       | abs(2-5)+abs(3-1) = 5 | abs(6-5)+abs(3-1) = 3 |
|        | (5, 3) | B       | abs(2-5)+abs(3-3) = 3 | abs(6-5)+abs(3-3) = 1 |
|        | (5, 6) | B       | abs(2-5)+abs(3-6) = 6 | abs(6-5)+abs(3-6) = 4 |
|        | (6, 2) | B       | abs(2-6)+abs(3-2) = 5 | abs(6-6)+abs(3-2) = 1 |
|        | (6, 3) | B       | abs(2-6)+abs(3-3) = 4 | 0                     |
| (6, 3) | (7, 4) | B       | abs(2-7)+abs(3-4) = 6 | abs(6-7)+abs(3-4) = 2 |
```

trying `pandoc .\debug_5cols.md -o .\debug_5cols.pdf --template eisvogel` directly just breaks:

```txt
Error producing PDF.
! Undefined control sequence.
<argument> ...rtpbox {\@nextchar }\insert@pcolumn 
                                                  \@endpbox \do@row@strut \o...
l.271 ...width - 8\tabcolsep) * \real{0.3239}}@{}}
```

Relates to #434 

If I simply leave out the last column (left side of the image below) it just works with any engine, however with the last column (right side below) vastly different .tex is generated.

```sh
pandoc .\debug_4cols.md -o .\debug_4cols.tex --template eisvogel
pandoc .\debug_5cols.md -o .\debug_5cols.tex --template eisvogel
```

### 11 vs. 12 (vs. 16) Columns (max width 54/79/105 characters)

Breaks at 16 Columns, breaks with at least 12 columns, works with at most 11 columns.

`pandoc .\debug_long.md -o debug_long.pdf --template eisvogel`

Is there a best practice (and good way to communicate that to the user) how to handle tables of any width?
