Set scrollbar to the LEFT with grid layout manager

I get read, that you can place the scollbar to the LEFT in .pack() layout manager, but I can't find a working solution for .grid() layout manager. The description in my book say I should use sticky = 'nsw' for location. Than I tried to move it to the left, see my example.

This doesn't have any effect:

import tkinter as tk
from tkinter import ttk
from pathlib import Path

root = tk.Tk()

root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)

paths = Path('.').glob('**/*')

tv = ttk.Treeview(root, columns=['size','modified'], selectmode=None)

tv.heading('#0', text='Name')
tv.heading('size', text='Size', anchor='center')
tv.heading('modified', text='Modifies', anchor='center')

tv.column('#0', stretch = True, anchor='w')
tv.column('size', width=100, anchor='center') 
tv.column('modified',anchor='center')

tv.grid_rowconfigure(0, weight=1)
tv.grid_columnconfigure(0, weight=1) 
tv.grid(row=0, column=0, sticky='nsew')
#tv.pack(expand=True, fill='both')

for path in paths:
    meta = path.stat()
    parent = str(path.parent)
    if parent == '.':
        parent = ''
               
    tv.insert(parent, 'end', iid=str(path), text=str(path.name), values=[meta.st_size, meta.st_mtime])

scrollbar = ttk.Scrollbar(root, orient=tk.VERTICAL, command=tv.yview)
tv.configure(yscrollcommand=scrollbar.set)
scrollbar.grid(row=0, column=1, sticky='nse') #scrollbar goes not to the left!
        
root.mainloop()

Is it in treeview not possible to locate the the scrollbar to the LEFT side of the window?

Solution

If you change tv's column to 1 and scrollbar's to 0, it'll do what you want

import tkinter as tk
from tkinter import ttk
from pathlib import Path

root = tk.Tk()

root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)

paths = Path('.').glob('**/*')

tv = ttk.Treeview(root, columns=['size','modified'], selectmode=None)

tv.heading('#0', text='Name')
tv.heading('size', text='Size', anchor='center')
tv.heading('modified', text='Modifies', anchor='center')

tv.column('#0', stretch = True, anchor='w')
tv.column('size', width=100, anchor='center')
tv.column('modified',anchor='center')

tv.grid_rowconfigure(0, weight=1)
tv.grid_columnconfigure(0, weight=1)
tv.grid(row=0, column=1, sticky='nsew')  # set this to column 1
#tv.pack(expand=True, fill='both')

for path in paths:
    meta = path.stat()
    parent = str(path.parent)
    if parent == '.':
        parent = ''

    tv.insert(parent, 'end', iid=str(path), text=str(path.name), values=[meta.st_size, meta.st_mtime])

scrollbar = ttk.Scrollbar(root, orient=tk.VERTICAL, command=tv.yview)
tv.configure(yscrollcommand=scrollbar.set)
scrollbar.grid(row=0, column=0, sticky='ns')  # set this to column 0 
# (you can also just use sticky='ns' if you want)

root.mainloop()
