Tkinter TreeVIew 水平滚动条不起作用

问：

我正在使用 tkinter 和 treeview 构建一个普通表。水平滚动条是可见的，但未激活，尽管我已经配置了设置。想知道代码有什么问题吗？

login_window = tk.Tk()
login_window.geometry('950x600')

Table_frame = tk.Frame(login_window, bd=15, relief='ridge', width=900, height=200)
Table_frame.grid(row=3, column=0, sticky='nsew')

destination_table = ttk.Treeview(Table_frame)
destination_table.pack(fill=BOTH, expand=1)

scroll_x = ttk.Scrollbar(Table_frame, orient='horizontal')
scroll_x.configure(command=destination_table.xview)
scroll_x.pack(side=BOTTOM, fill=X)

destination_table.configure(xscrollcommand = scroll_x.set)

destination_table["columns"]=("destinationname", "rate", "description", "estimatedprice","address", "contact", "operationtime", "type", "tags")

destination_table["show"] = "headings"

destination_table.heading("destinationname", text="Destination Name")
destination_table.heading("rate", text="Ratings")
destination_table.heading("description", text="Description")
destination_table.heading("estimatedprice", text="Estimated Price")
destination_table.heading("address", text="Address")
destination_table.heading("contact", text="Contact")
destination_table.heading("operationtime", text="Operation Time")
destination_table.heading("type", text="Destination type")
destination_table.heading("tags", text="Tags")


destination_table.column("destinationname", width=100)

login_window.mainloop()
