填充未显示在 tkinter 网格中

Question

I have tried making a basic tkinter ttk program, but the frame's padding between each other is gone. I am using grid, which should have (maybe) caused the problem. I am a beginner and I require help. Here is the code:

from tkinter import *
from tkinter import ttk

def donothing():
    print("i see")

root = Tk()
root.title("Application")
root.geometry("1000x1000")

s=ttk.Style()
s.configure('TFrame', background='gray')
s.configure('windowframes.TFrame', background='darkgray')

mainframe = ttk.Frame(root, padding="5 5 5 5",height=300)
mainframe.grid(column=0, row=0, sticky=(N,E,S,W))


menu = Menu(root)
root.config(menu=menu)
filemenu = Menu(menu,tearoff=0)
filemenu.add_command(label="New", command=donothing)
filemenu.add_command(label="Open", command=donothing)
filemenu.add_command(label="Save", command=donothing)
filemenu.add_command(label="Save as...", command=donothing)
filemenu.add_command(label="Close", command=donothing)

filemenu.add_separator()

filemenu.add_command(label="Exit", command=root.quit)
menu.add_cascade(label="File", menu=filemenu)

toolframe = ttk.Frame(mainframe,padding="5 5 5 5",height=40,style='windowframes.TFrame')
toolframe.grid(column=0, row=0, sticky=(N,E,W))
mainframe.columnconfigure(0,weight=2)

hierarchyframe = ttk.Frame(mainframe,padding="5 5 5 5",width=300,style='windowframes.TFrame')
hierarchyframe.grid(column=0, row=1, sticky=(S,W,N))
mainframe.rowconfigure(1,weight=1)

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

root.mainloop()

acw1668 was right, just change it from making the Frame and putting padding there, instead put it in.grid function, as in

hierarchyframe = ttk.Frame(mainframe,width=300,style='windowframes.TFrame')
hierarchyframe.grid(column=0, row=1, sticky=(S,W,N), padx=2, pady=2)

Thank you
