tabulator doesn't work in an offline notebook context #3959
Open
Description
Panel already bundles in the tabulator extension js/css dependencies, but somehow it is not used in inline mode in a jupyter notebook, which makes it not work without internet connectivity.
xref: holoviz/holoviews#5469 (comment)
ALL software version info
Python: 3.9
panel: 0.13.1
Description of expected behavior and the observed behavior
Expected behavior: a tabulator based widget should show up with the data from the dataframe.
Observed behavior: Blank output: panel fails loading the tabulator files since they are requested from cdn which is not accessible without internet connection
Complete, minimal, self-contained example code that reproduces the issue
In a jupyter notebook in a browser without internet access. Easiest way to get it it to start firefox as follows (linux):
$ env http_proxy=http://localhost:1/ https_proxy=http://localhost:1/ firefox --profile nointernet
# notebook code
import pandas as pd
df = pd.DataFrame({'a':range(10),'b':range(10,20)})
import panel as pn
print(pn.__version__)
pn.extension('tabulator', inline=True)
display(pn.widgets.Tabulator(df))
