如何在HoloViz面板制表器小部件中配置标题过滤器？

import panel as pn
import pandas as pd

pn.extension()

data = {'Name': ['John', 'Alice', 'Bob'],
        'Age': [25, 30, 35],
        'City': ['New York', 'London', 'Paris']}
df = pd.DataFrame(data)
table = pn.widgets.DataFrame(df)

title_filter = pn.widgets.TextInput(name='Title Filter')

def filter_table(event):
    filtered_df = df[df.columns[df.columns.str.contains(title_filter.value)]]
    table.value = filtered_df

title_filter.param.watch(filter_table, 'value')

layout = pn.Column(title_filter, table)

layout.show()
