如何在Bokeh中从DataTable对象中选择文本

from bokeh.models import ColumnDataSource, DataTable, StringFormatter, StringEditor, StringFilter, SelectEditor, NumberEditor
from bokeh.layouts import layout
from bokeh.io import curdoc

# 创建ColumnDataSource对象
source = ColumnDataSource(data=dict(
    name=["John", "Jane", "Mike", "Emily"],
    age=[25, 30, 35, 40],
    city=["New York", "London", "Paris", "Tokyo"]
))

# 创建DataTable对象
columns = [
    TableColumn(field="name", title="Name", editor=StringEditor(), formatter=StringFormatter(font_style="bold")),
    TableColumn(field="age", title="Age", editor=NumberEditor()),
    TableColumn(field="city", title="City", editor=SelectEditor(options=["New York", "London", "Paris", "Tokyo"])),
]
data_table = DataTable(source=source, columns=columns, editable=True, index_position=-1, index_header="Index")

# 创建布局
layout = layout([[data_table]])

# 将布局添加到文档
curdoc().add_root(layout)
