Description of expected behavior and the observed behavior

Attempting to disable header sort. It works when creating a tabulator object normally as is shown in the documentation.
https://panel.holoviz.org/reference/widgets/Tabulator.html#static-configuration
Does not seem to work when created from a param object.

Complete, minimal, self-contained example code that reproduces the issue

Does not work:

import pandas as pd
import panel as pn
import param
pn.extension('tabulator')

class TestClass(param.Parameterized):
    df = pd.DataFrame({
    'int': [1, 2, 3],
    'float': [3.14, 6.28, 9.42],
        }, index=[1, 2, 3])
    
    param_df=param.DataFrame(df)

c=TestClass()

pn.widgets.Tabulator.from_param(c.param.param_df,configuration={
    'columnDefaults': {
        'headerSort': False,
    },})

Works:

df = pd.DataFrame({
    'int': [1, 2, 3],
    'float': [3.14, 6.28, 9.42],
}, index=[1, 2, 3])


pn.widgets.Tabulator(df,configuration={
    'columnDefaults': {
        'headerSort': False,
    },})

Stack traceback and/or browser JavaScript console output

None

Seems like configuration is not implemented as a parameter of Tabulator right now. Due to the special handling Param doesn't recognize configuration and simply drops it. As I'm releasing 1.0.3 shortly I don't want to mess this deeply with Tabulator before the release but I may get a warning about the parameter being dropped in.

Work around that has worked for me in the mean time:

tab_obj = pn.widgets.Tabulator.from_param(...)

tab_obj._configuration["columnDefaults"] = {"headerSort": False}
