How should a scrollable spreadsheet be displayed within Tkinter?

问题

Currently I am using a Treeview. The problem is that I am using quite a large data set. So that the GUI isn't massive, I've limited the size of the Treeview to fit the window and added vertical and horizontal scrollbars. It displays the data exactly how I want, however there are speed issues when scrolling in each direction. Is there a better/faster way to display spreadsheet-like data.

The below solution is cobbled together but should achieve the desired result:

from tkinter import *

class App:
    def __init__(self, root):
        self.entry = []
        self.sv = []
        self.root = root
        self.canvas = Canvas(self.root, background="#ffffff", borderwidth=0)
        self.frame = Frame(self.canvas, background="#ffffff")
        self.scrolly = Scrollbar(self.root, orient="vertical", command=self.canvas.yview)
        self.scrollx = Scrollbar(self.root, orient="horizontal", command=self.canvas.xview)
        self.canvas.configure(yscrollcommand=self.scrolly.set)#, xscrollcommand=self.scrollx.set)
        self.canvas.create_window((4,4), window=self.frame, anchor="nw", tags="self.frame")
        self.scrolly.pack(side="left", fill="y")
        self.canvas.pack(side="top", fill="both", expand=True)
        self.scrollx.pack(side="bottom", fill="x")
        self.frame.bind("<Configure>", self.onFrameConfigure)
        for i in range(15):
            self.entry.append([])
            self.sv.append([])
            for c in range(30):
                self.sv[i].append(StringVar())
                self.sv[i][c].trace("w", lambda name, index, mode, sv=self.sv[i][c], i=i, c=c: self.callback(sv, i, c))
                self.entry[i].append(Entry(self.frame, textvariable=self.sv[i][c]).grid(row=c, column=i))
    def onFrameConfigure(self, event):
        self.canvas.configure(scrollregion=self.canvas.bbox("all"))
    def callback(self, sv, column, row):
        print("Column: "+str(column)+", Row: "+str(row)+" = "+sv.get())

root = Tk()
App(root)
root.mainloop()

I ended up using pandastable (https://github.com/dmnfarrell/pandastable). As it provided a quick and easy way of displaying data in a spreadsheet like manner. It also provides a lot of built in functionality, such as: sorting, filtering and applying functions to columns
