您可以在PySimpleGUI表对象的行中添加隐藏值吗？

import PySimpleGUI as sg

data = [
    ['John', 'Doe', 'john.doe@example.com'],
    ['Jane', 'Smith', 'jane.smith@example.com'],
    ['Bob', 'Johnson', 'bob.johnson@example.com']
]

layout = [
    [sg.Table(values=data, headings=['First Name', 'Last Name', 'Email'], key='-TABLE-', metadata=data)],
    [sg.Button('Get Hidden Values')]
]

window = sg.Window('Table Example', layout)

while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break
    elif event == 'Get Hidden Values':
        table = window['-TABLE-']
        hidden_values = table.metadata
        sg.popup('Hidden Values:', hidden_values)

window.close()
