I had a play and here is a simple DisplayTable widget.
Its still not a scrollable frame (although i might get round
to that later...) But it takes a list of headings and a 2D
list of data values and creates a display grid.

You can tweak the colours somewhat. Its a long way from
polished but should serve as a starter...

########## displaytable.py ##########

try:
  import Tkinter as tk  # v2
except ImportError:
  import tkinter as tk  # v3

class DisplayTable(tk.Frame):
    def __init__(self, parent, headings, data,
                 hdcolor='red', datacolor='black',
                 gridcolor= 'black', cellcolor='white'):
        tk.Frame.__init__(self, parent, bg=gridcolor)

        if len(headings) != len(data[0]): raise ValueError
        self.headings = headings

        for index,head in enumerate(headings):
            width = len(str(head))
            cell = tk.Label(self,text=str(head),
                            bg=cellcolor, fg=hdcolor, width=width)
            cell.grid(row=0,column=index, padx=1, pady=1)

        for index,row in enumerate(data):
            self.addRow(index+1,row,datacolor,cellcolor)

    def addRow(self, row, data, fg='black', bg='white'):
        for index, item in enumerate(data):
            width = len(str(self.headings[index]))
            cell = tk.Label(self,text=str(item),
                            fg=fg, bg=bg, width=width)
            cell.grid(row=row, column=index, padx=1,pady=1)


if __name__ == "__main__":
    top = tk.Tk()
    tab = DisplayTable(top,
                       ["Left","Right"],
                       [[1,2],
                        [3,4],
                        [5,6]],
                       datacolor='green')
    tab.pack()
    top.mainloop()
