使用for循环在pandas数据帧上创建bokeh data_table

import pandas as pd
from bokeh.models import ColumnDataSource
from bokeh.models.widgets import DataTable, DateFormatter, StringFormatter, NumberFormatter
from bokeh.io import output_notebook, show

data = {'Name': ['John', 'Emma', 'Michael', 'Sophia'],
        'Age': [25, 30, 35, 28],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)

source = ColumnDataSource(data=dict())

columns = []
data_table = DataTable(source=source, columns=columns, editable=True, index_position=-1)

layout = []

for column in df.columns:
    source.data[column] = df[column]
    if df[column].dtype == 'int64':
        formatter = NumberFormatter(format='0,0')
    else:
        formatter = StringFormatter()
    columns.append(TableColumn(field=column, title=column, formatter=formatter))

layout.append(data_table)

output_notebook()
show(layout)
