I want to add a horizontal scroll bar to the particular tree-view table since I have not used Tkinter before so please help!

import tkinter

def __create_tree_view(self):
        """ Creates a TreeView Layout with req Headers """
        style = it.Style()
        style.configure("Custom.Treeview.Heading",foreground="green", relief="flat")
        style.map("Custom.Treeview.Heading", relief=[('active','groove'),('pressed','sunken')])
        style.configure('Treeview', rowheight=20)
        #
        self.tree_view = ttk.Treeview(self.right_frame, selectmode ='browse',\
             style="Custom.Treeview")
        self.tree_view.grid(row=1, column=1, sticky=tk.NSEW)

        self.verticalscrollba = ttk.Scrollbar(self.right_frame, orient="vertical", \
            command=self.tree_view.view)
        self. verticalscrollbar.grid(row=1,column=1,sticky='nse')
        self.tree_view.configure(yscrollcommand = self.verscrlbar.set)
        # Defining number of columns
        self.tree_view["columns"] = ("1", "2", "3", "4")
        # Defining heading
        self.tree_view['show'] = 'headings'
        # Assigning the width and anchor to the respective columns
        self.tree_view.column("1", width = int(self.window_width/5),    anchor ='ca, stretch=False)
        self.tree_view.column("2", width = int(self.window_width/4)-30,    anchor ='ca, stretch=False)
        self.tree_view.column("3", width = int(self.window_width/6)-30, anchor ='ca, stretch=False)
        self.tree_view.column("4", width = int(self.window_width/3),    anchor ='ca, stretch=False)
        # Assigning the heading names to the respective columns
        self.tree_view.heading("1", text ="Brand/Model/Type")
        self.tree_view.heading("2", text ="Device_Id")
        self.tree_view.heading("3", text ="Device_Ip")
        self.tree_view.heading("4", text ="GUID")

where the brand is the brand of the device IP, is IP address and so here in this code how to add a horizontal scroll bar without overwriting the last line of the treeview table I tried to add the scrollbar but it's displaying on the last row of the table it should display below the last row of the table

Try this an example.

import tkinter as tk
from tkinter import ttk

class Chrisdb1(tk.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.tvw_results = ttk.Treeview(self, style = 'mystyle.Treeview')
        self.insert = self.tvw_results.insert

        self.tvw_results.grid(row = 0, column = 0, sticky='nsew')
        self.tvw_results.column("#0", minwidth = 1150)
        self.tvw_results.heading('#0', text = 'Found results', anchor = tk.W)

        # Scrollbars + attach scrollbars to TreeView
        sb_vertical = tk.Scrollbar(self, orient = "vertical", command = self.tvw_results.yview)
        sb_horizontal = tk.Scrollbar(self, orient = "horizontal", command = self.tvw_results.xview)
        self.tvw_results.configure(yscrollcommand = sb_vertical.set, xscrollcommand = sb_horizontal.set)
        sb_vertical.grid(row = 0, column = 1, sticky = "ns")
        sb_horizontal.grid(row = 1, column = 0, sticky = "ew")

        # Configure and position grid for TreeView
        self.grid_rowconfigure(0, weight = 1)
        self.grid_columnconfigure(0, weight = 1)

def main():
    '''test code for Chrisdb1 class'''
    root = tk.Tk()
    cnt_treeview = Chrisdb1(root)
    for i in range(20):
        cnt_treeview.insert('', tk.END, text = f'Row {i}: Some very long texxxxxxxt.....'*6)
    cnt_treeview.pack(expand=True, fill=tk.BOTH)
    root.mainloop()

if __name__ == '__main__':
    main()
