title: Tkinter grid problems
body: <p>Shouldn't the "One Label" expand to occupy the full width (minus the padding) of the column? It doesn't for me (OS X 10.9.5); it always appears justified left and occupying its natural width:</p>
  
  <pre><code>from Tkinter import *
  
  root = Tk()
  root.configure(background='black')
  
  frame = Frame(root, bg='red', takefocus=0)
  frame.pack()
  
  l0 = Frame(frame, bg='blue')
  l0.grid(row=0, sticky=W+E)
  l0x=Label(l0,text='One Label', takefocus=1)
  l0x.grid(padx=2, pady=2, sticky=W+E)
  
  l1 = Frame(frame, bg='yellow')
  l1.grid(row=1, sticky=W+E)
  l1x=Label(l1,text='Another Label', takefocus=1)
  l1x.grid(padx=2, pady=(0,2), sticky=W+E)
  
  root.mainloop()
  </code></pre>
