pn.widgets.Tabulator with sizing_mode="stretch_width" or max_width results in odd styling issues

[kdheepak]

Try running the following code with panel serve:

import panel as pn
import pandas as pd

pn.extension("tabulator")

df = pd.DataFrame({f"scenario-{i}": [1, 2, 3] for i in range(0, 100)})

layout = pn.widgets.Tabulator(df, max_width=800)

layout.servable()

This causes issues when scrolling left and right:

This also causes an issue when using frozen columns. For example, change the line creating a layout to this:

layout = pn.widgets.Tabulator(
    df, max_width=800, frozen_columns=["scenario-1", "scenario-2"]
)

and you'll see this kind of behavior where the frozen columns are not frozen anymore:

ALL software version info

I'm using the latest version of panel:

I made a fresh environment using uv to test this. I've attached the source code with the uv.lock file in the following zip file:

test-panel-tabulator.zip

You can run uv sync and uv run panel serve main.py to reproduce the issue:
