Tkinter Treeview網格對齊問題

如何在放大應用程序窗口時將樹視圖窗口小部件粘貼到Noth（工具欄）。Tkinter Treeview網格對齊問題

它堅持西南和東，但不是北。

使用：

self.tree.grid(row=1,column=0,sticky=N+W+E+S)

我這在tree.grid對準配置

... 
    self.vsb = ttk.Scrollbar(master, orient=VERTICAL, command=self.tree.yview) 
    self.hsb = ttk.Scrollbar(master, orient=HORIZONTAL, command=self.tree.xview) 
    self.vsb.grid(row=1, column=1, sticky='ns') 
    self.hsb.grid(row=2, column=0, sticky='ew') 
    self.tree.configure(yscrollcommand=self.vsb.set) 
    self.tree.configure(xscrollcommand=self.hsb.set) 

    self.tree.grid(row=1,column=0,sticky=N+W+E+S) 
...

這是工具欄網格配置（如果它導致問題）

... 
     self.toolbar = Frame(master, bg="blue") 
     self.upButton = Button(self.toolbar, text="Up", command=self.doNothing, padx=10, pady=10) 
     self.upButton.grid(row=0,column=0,sticky=N+W) 

     self.downButton = Button(self.toolbar, text="Down", command=self.doNothing, padx=10, pady=10) 
     self.downButton.grid(row=0,column=1, sticky=N+W) 

     self.insupButton = Button(self.toolbar, text="Insert UP", command=lambda: self.insertUp(self.tree), padx=10, pady=10) 
     self.insupButton.grid(row=0,column=2, sticky=N+W) 

     self.insdownButton = Button(self.toolbar, text="Insert Down", command=lambda: self.insertDown(self.tree), padx=10, pady=10) 
     self.insdownButton.grid(row=0,column=3, sticky=N+W) 

     self.delbrButton = Button(self.toolbar, text="Delete branch", command=lambda: self.deleteBr(self.tree), padx=10, pady=10) 
     self.delbrButton.grid(row=0,column=4, sticky=N+W) 

     self.deltreeButton = Button(self.toolbar, text="Delete entire tree", command=lambda: self.deleteTr(self.tree), padx=10, pady=10) 
     self.deltreeButton.grid(row=0,column=5, sticky=N+W) 

     self.searchButton = Button(self.toolbar, text='Search', command=lambda: self.searchTr(self.tree), padx=10, pady=10) 
     self.searchButton.grid(row=0,column=6, sticky=N+W) 

     self.calcButton = Button(self.toolbar, text='Calc', command=lambda: self.calcTree(self.tree), padx=10, pady=10) 
     self.calcButton.grid(row=0,column=7, sticky=N+W) 

     self.toolbar.grid(row=0,column=0, sticky=N+W) 
...
