目前没有找到您点击哪个标题的现有方法，因此此处需要 tkinter 代码。

下面demo代码中双击表头排序，表格如何排序，取决于你的排序代码，这里不展示。

import PySimpleGUI as sg


def double_click(event):
    """
    Additional event for double-click on header
    event: class event
    """
    region = table.identify("region", event.x, event.y)
    if region == 'heading':                                 # Only care double-clock on headings
        cid = int(table.identify_column(event.x)[1:])-1     # check which column clicked
        window.write_event_value("-TABLE-DOUBLE-CLICK-", cid)
