如何按降序（9，7，5，4，3，1）对Badge列编号进行排序？当然，通过对Badge数字排序，行的顺序也会改变。我想得到：

5,"Frank","9"
3,"Daniel","7"
4,"Leonard","5"
1,"Jack","4"
6,"Robert","3"
2,"Tom","1"

我在网上找到了一些例子，但我无法将它们应用到我的代码中。你能用我的代码告诉我解决方案吗？
代码：

from tkinter import *
from tkinter import ttk

ws = Tk()
ws.title('PythonGuides')
ws.geometry('400x300')
ws['bg']='#fb0'

data  = [
    [1,"Jack","4"],
    [2,"Tom","1"],
    [3,"Daniel","7"],
    [4,"Leonard","5"],
    [5,"Frank","9"],
    [6,"Robert","3"],
    ]

tv = ttk.Treeview(ws)
tv['columns']=('Rank', 'Name', 'Badge')
tv.column('#0', width=0, stretch=NO)
tv.column('Rank', anchor=CENTER, width=80)
tv.column('Name', anchor=CENTER, width=80)
tv.column('Badge', anchor=CENTER, width=80)
tv.heading('#0', text='', anchor=CENTER)
tv.heading('Rank', text='Id', anchor=CENTER)
tv.heading('Name', text='rank', anchor=CENTER)
tv.heading('Badge', text='Badge', anchor=CENTER)
tv.pack()

def func1():
    for record in data:
        Rank = record[0]
        Name = record[1]
        Badge = record[2]
        
        datagrid = [Rank, Name, Badge]

        tv.insert(parent='', index='end', values=(datagrid))

button = Button(ws, text="Button", command = func1)
button.place(x=1, y=1)

ws.mainloop()

python-3.x
