Creating a table look-a-like Tkinter

A fairly simple object-less solution I found:

from Tkinter import *

rows = []
for i in range(5):
    cols = []
    for j in range(4):
        e = Entry(relief=RIDGE)
        e.grid(row=i, column=j, sticky=NSEW)
        e.insert(END, '%d.%d' % (i, j))
        cols.append(e)
    rows.append(cols)

def onPress():
    for row in rows:
        for col in row:
            print col.get(),
        print

Button(text='Fetch', command=onPress).grid()
mainloop()

or

# simple 2d table

from Tkinter import *

for i in range(5):
    for j in range(4):
        l = Label(text='%d.%d' % (i, j), relief=RIDGE)
        l.grid(row=i, column=j, sticky=NSEW)

mainloop()

What problem are you having? The simple solution is to lay out widgets using grid. You can put whatever type of widget you want in each cell. And yes, labels can have borders. Though, a simple way to do grid lines is to use a padding around each cell, so that the color of the frame will show through the gaps.

Do this in a frame. If you need to be able to scroll the table, put the frame inside a canvas and add scrollbars. There are examples all over the web for how to create a scrollable frame using a canvas.

Here's a really quick example that uses just labels, and doesn't scroll. I'll leave the exact implementation of what you need as an exercise for the reader.

import Tkinter as tk

class ExampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        t = SimpleTable(self, 10,2)
        t.pack(side="top", fill="x")
        t.set(0,0,"Hello, world")

class SimpleTable(tk.Frame):
    def __init__(self, parent, rows=10, columns=2):
        # use black background so it "peeks through" to 
        # form grid lines
        tk.Frame.__init__(self, parent, background="black")
        self._widgets = []
        for row in range(rows):
            current_row = []
            for column in range(columns):
                label = tk.Label(self, text="%s/%s" % (row, column), 
                                 borderwidth=0, width=10)
                label.grid(row=row, column=column, sticky="nsew", padx=1, pady=1)
                current_row.append(label)
            self._widgets.append(current_row)

        for column in range(columns):
            self.grid_columnconfigure(column, weight=1)


    def set(self, row, column, value):
        widget = self._widgets[row][column]
        widget.configure(text=value)

if __name__ == "__main__":
    app = ExampleApp()
    app.mainloop()
