如何使用ipywidget选择熊猫DataFrame？

import ipywidgets as widgets
from IPython.display import display
import pandas as pd

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

column_dropdown = widgets.Dropdown(options=df.columns, description='Column:')

filter_textbox = widgets.Text(description='Filter:')

filter_button = widgets.Button(description='Filter')

output_area = widgets.Output()

def filter_dataframe(column, value):
    filtered_df = df[df[column] == value]
    with output_area:
        display(filtered_df)

def filter_button_clicked(button):
    output_area.clear_output()
    filter_dataframe(column_dropdown.value, filter_textbox.value)

filter_button.on_click(filter_button_clicked)

display(column_dropdown, filter_textbox, filter_button)
display(output_area)
