如何在Dash中使用python将html_Table转换为pandas数据帧？

import dash
import dash_html_components as html
import pandas as pd

app = dash.Dash(__name__)

html_table = '''
<table>
  <thead>
    <tr>
      <th>Column 1</th>
      <th>Column 2</th>
      <th>Column 3</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Value 1</td>
      <td>Value 2</td>
      <td>Value 3</td>
    </tr>
    <tr>
      <td>Value 4</td>
      <td>Value 5</td>
      <td>Value 6</td>
    </tr>
  </tbody>
</table>
'''

df = pd.read_html(html_table)[0]

app.layout = html.Div([
    html.H1('Pandas数据帧'),
    html.Table([
        html.Thead(
            html.Tr([html.Th(col) for col in df.columns])
        ),
        html.Tbody([
            html.Tr([
                html.Td(df.iloc[i][col]) for col in df.columns
            ]) for i in range(len(df))
        ])
    ])
])

if __name__ == '__main__':
    app.run_server(debug=True)
