import tkinter
from tkinter import ttk #     
 
win=tkinter.Tk()
tree=ttk.Treeview(win)#  
tree["columns"]=("  ","  ","  ")
tree.column("  ",width=100) #   ,   
tree.column("  ",width=100)
tree.column("  ",width=100)
 
tree.heading("  ",text="  -name") #    
tree.heading("  ",text="  -age")
tree.heading("  ",text="  -tall")
 
tree.insert("",0,text="line1" ,values=("1","2","3")) #    ，
tree.insert("",1,text="line1" ,values=("1","2","3"))
tree.insert("",2,text="line1" ,values=("1","2","3"))
tree.insert("",3,text="line1" ,values=("1","2","3"))
 
tree.pack()
win.mainloop()
