在google中使用“如何使tkinter網格擴展”，我遇到了這個問題。

引用布萊恩·奧克利的話Rows and columns have "weight" which describes how they grow or shrink to fill extra space >in the master. By default a row or column has a weight of zero, which means you've told the >label to fill the column but you haven't told the column to fill the master frame.

要解決這個問題，給柱子一個重量。class Test():

def __init__(self,root):

self.root = root

self.root.columnconfigure(0, weight=1)

self.root.config(bg='green')

self.message = 'test message'

self.contentFrame = Frame(self.root)

self.contentFrame.config(background='black',borderwidth=5,relief ='sunken')

self.contentFrame.grid(row=0, column=0, sticky='news')

self.contentFrame.columnconfigure(0, weight=1)

self.topBar = Frame(self.contentFrame, border=2, relief=RAISED)

self.topBar.grid(row=0, column=0, columnspan=23,sticky=W+E)

self.topBar.config(background='blue')

self.topBar.columnconfigure(0, weight=1)

self.newGameButton = Button(self.topBar, text="New Game")

self.newGameButton.grid(row=0, column=0)

self.newGameButton.config(background='red')

self.messageBox = Label(self.topBar, text=self.message, height=2)

self.messageBox.grid(row=1, column=0, columnspan=1,sticky=W+E)

self.messageBox.config(background='yellow')

Test(root)
