为什么粘性方法在Python Tkinter中不起作用？

Question

我为我的pomodoro应用程序创建了界面的草稿。我想锚定标签标题到左边。要做到这一点，我想使用粘性方法。不幸的是，它什么也做不了。你能告诉我我哪里做错了吗？

import tkinter as tk

window = tk.Tk()
window.geometry("500x300")
window.title("Pomodoro by Gringo")

# HEADER - WORK START/STOP
label_work = tk.Label(text="PRACA", relief="groove", borderwidth=3)
label_work.grid(column=0, row=0, stick=tk.W, padx=150, pady=10)

button_start_work = tk.Button(text="START")
button_start_work.grid(column=1, row=0)

button_stop_work = tk.Button(text="STOP")
button_stop_work.grid(column=2, row=0)

# MAIN - POMODORO START/STOP
label_pom = tk.Label(text="POMODORO", relief="groove", borderwidth=3)
label_pom.grid(column=0, row=2, stick=tk.W, padx=150, pady=10)

button_start_pom= tk.Button(text="START")
button_start_pom.grid(column=1, row=2)

button_stop_pom = tk.Button(text="STOP")
button_stop_pom.grid(column=2, row=2)

window.mainloop()

上述代码的结果如下所示。但是我想把标题移到左边。

设置padx=150会在标签的右侧和左侧设置填充。你可能想要这个：

import tkinter as tk

window = tk.Tk()
window.geometry("500x300")
window.title("Pomodoro by Gringo")

# HEADER - WORK START/STOP
label_work = tk.Label(text="PRACA", relief="groove", borderwidth=3)
label_work.grid(column=0, row=0, stick=tk.W, padx=(0,150), pady=10)

button_start_work = tk.Button(text="START")
button_start_work.grid(column=1, row=0)

button_stop_work = tk.Button(text="STOP")
button_stop_work.grid(column=2, row=0)

# MAIN - POMODORO START/STOP
label_pom = tk.Label(text="POMODORO", relief="groove", borderwidth=3)
label_pom.grid(column=0, row=2, stick=tk.W, padx=(0,150), pady=10)

button_start_pom= tk.Button(text="START")
button_start_pom.grid(column=1, row=2)

button_stop_pom = tk.Button(text="STOP")
button_stop_pom.grid(column=2, row=2)

window.mainloop()
