如何替换Bokeh DataTable中的索引列？

from bokeh.io import show
from bokeh.models import ColumnDataSource, DataTable, NumberFormatter, StringFormatter, StringEditor, NumberEditor, StringInput, NumberInput
from bokeh.layouts import column
from bokeh.plotting import curdoc

# 创建一个示例数据
data = {'Name': ['Alice', 'Bob', 'Charlie'],
        'Age': [25, 30, 35],
        'City': ['New York', 'London', 'Paris']}

# 创建一个新的列数据源
index_data = {'Index': list(range(1, len(data['Name']) + 1))}
index_source = ColumnDataSource(index_data)

# 创建新的列对象
index_column = DataTable.Column(field='Index', title='Index', formatter=NumberFormatter(format='0'), editor=NumberEditor(step=1, mode='immediate', low=1), width=50)

# 创建DataTable对象
data_table = DataTable(source=index_source, columns=[index_column], editable=True, index_position=None, index_header='Index')

# 显示DataTable
show(data_table)
