如何在没有tkinter中心窗口小部件的情况下向tkinter窗口添加填充？我试过了:
self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12")
self.canvas_l.grid(row=9, column=1, sticky=S, ipady=30)
和
self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12")
self.canvas_l.grid(row=9, column=1, rowspan=2, sticky=S, pady=30)
我只想在标签的顶部添加30px填充.
