DataTables warning with Quarto and Pandas Styler

[SvenKlaassen]

When using pandas style with quarto, the html files display the following DataTables warning.

DataTables warning: Non-table node initialisation (DIV). For more information about this error, please see https://datatables.net/tn/2

A minimal example is

quarto --version
1.5.57

itables v2.1.5

---
title: "iTables with Caption and Pandas Styler"
format: html
---

```{python}
import numpy as np
import pandas as pd
from itables import init_notebook_mode

from itables.version import __version__

print(f"This is itables v{__version__}")
init_notebook_mode(all_interactive=True)

x = np.linspace(0, np.pi, 21)
df = pd.DataFrame({"sin": np.sin(x), "cos": np.cos(x)}, index=pd.Index(x, name="alpha"))

s = df.style

s.format("{:.3f}").format_index("{:.3f}")

s.set_caption("A Pandas Styler object").set_table_styles(
    [{"selector": "caption", "props": "caption-side: bottom; font-size:1em;"}]
)

The warning does not occur if the caption is not set.

Hi @SvenKlaassen , thank you for the precise and helpful bug report! I have been able to reproduce and fix the problem in my dev environment.

May I ask you to give it a try as well? See the instructions at #318 (comment). Thanks!

[SvenKlaassen]

Thank you for the very fast reply @mwouts!
The fix also solves the issue for me.

You're welcome! Actually I see that, while the change fixes the issue in Quarto, it introduces a very significant regression (e.g. itables stops working in all the other contexts!!). I'll have a look and keep you posted!

I've updated the PR, can you let me know if it still works for you? Thanks!

[SvenKlaassen]

I still works perfectly on the PR.
Thanks again for the very fast update!
