My code successfully loads the CSV data into the tk.grid entry. However, I am encountering an error when attempting to load all the tk.grid data into a pandas dataframe. I would appreciate it if you could review my code and provide me with some ideas on how to accomplish this task.

import tkinter
import csv
import pandas as pd

root = tkinter.Tk()

# open file
with open("c:/erp/book1.csv", newline="") as file:
    reader = csv.reader(file)
    
    df1=pd.read_csv('c:/erp/book1.csv')
    df_list=list(df1.columns.values)
    df_rset=df1.to_numpy().tolist()


    # r and c tell us where to grid the labels
    for r, col in enumerate(reader):
        for c, row in enumerate(col):

            mlabel = tkinter.Entry(  root, width=10  )

            mlabel.grid(row=r, column=c,sticky="ew")
            mlabel.insert(0, row)
                                               
            dataFrame = pd.DataFrame()
            new_row=  df_list 
            a,b = root.grid_size()
            
                        

            
            for c in a:
                for r in b:
                    dataFrame.append(mlabel.grid[c][r])  #  it give error 
    
root.mainloop()

  for c in a:
                for r in b:
                    dataFrame.append(mlabel.grid[c][r])  #  it give error
