title: Facing Issue on Inserting Data to correct Column in Tkinter TreeView
body: <p>Can you please take a look at this Tkinter code and let me know why I am not able to insert the values to correct columns?</p>
  
  <p>as you can see from the attached image it seems it is adding empty string to first column! </p>
  
  <pre><code>from Tkinter import *
  import ttk
  
  root = Tk()
  
  tree = ttk.Treeview( root, columns=('Impacted Features'))
  tree.heading('#0', text='Feature Class')
  tree.heading('#1', text='Impacted Features')
  tree.column('#0', width=100)
  tree.column('#1', width=160)
  
  tree.grid(row=4, columnspan=6, sticky='nsew')
  tree.insert( "",0,  values=("1A","1b"))
  
  root.mainloop()
  </code></pre>
