Tkinter displaying button instead of Label

Question

I am creating a little app that will take in details from the user about a bank transaction and then display it in a table. I am currently using a CSV file to store the data and then when a new piece of data is put in, it will display that too.

I have a list of labels and then a button at the bottom of them to submit new entry. The problem I am getting is when the length of the table exceeds what it was to begin with there is a display error.

class accountant(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        master.title("Accountant")
        self.pack()
        self.numIncoming = 0
        self.numOutgoing = 0
        self.incoming = fs.fileStore("incoming", "csv")
        print("log: incoming.csv opened sucessfully")
        self.outgoing = fs.fileStore("outgoing", "csv")
        print("log: outgoing.csv opened sucessfully")
        self.setup()

    def setup(self):


        self.paint()

filestore is just a class that basically opens the csv using reader = csv.reader(open(file+'.'fileExt)) where file and fileExt are the parameters passed in.

Here is the image after a new entry. the bottom two buttons should stay as they are and the top two should be d e f in the left column and just whitespace in the right column

Replace self.pack() with self.grid(). To change a Label to Button you will, in addition, have to define a command function that executes when the Button is pressed, see the code below

bttn = tk.Button(self, text = "buttontitle",  command = self.do_function )
bttn.grid(row = 14, column = 4, sticky = W)


def do_function():
    print "HI"
