How do I center widgets on tkinter?-CodePudding

I'm really new to tkinter, and I've been trying to build a GUI that can add/delete users and put all the users inside a table. But I'm having trouble centering the add entry frame (where name,age,gender widgets are stored) and the delete entry frame (where id widgets are stored). I also want to fill the lower portion of the window with the table. I've been trying to use paddings to do this but to no avail. Here's my code:

from tkinter import *
from tkinter import ttk  

## GUI

root = Tk()
root.geometry('800x800')
root.resizable(False,False)

 # top frame
top_frame = Frame(root, bg= '#e3e6e4')
top_frame.grid(row= '0',column= '0',ipadx= '200')

## TABLE
user_columns = ('id','name', 'age', 'gender')
table = ttk.Treeview(root, columns= user_columns, show = 'headings', height = '6')
table.grid(row= '1', column = '0',padx = '20',pady= '20')

# heading config
table.heading('id', text= 'ID')
table.heading('name', text= 'Name')
table.heading('age', text= 'Age')
table.heading('gender', text= 'Gender')

## ADD ENTRY FEATURE
add_entry_frame = Frame(top_frame, bg='blue',bd='5')
add_entry_frame.grid(row= '0',column = '0',padx= '20',pady= '20')

    # Name
name_label = Label(add_entry_frame, text='Name:',bg= '#e3e6e4')
name_entry = Entry(add_entry_frame,width='20',borderwidth = '2')

name_label.grid(row= '0',column = '0')
name_entry.grid(row= '0',column = '1')

    # Age
age_label = Label(add_entry_frame,text='Age:',bg= '#e3e6e4')
age_entry = Entry(add_entry_frame,width='20',borderwidth = '2' )

age_label.grid(row= '1',column = '0')
age_entry.grid(row= '1',column = '1')

    # Gender
gender_label = Label(add_entry_frame,text='Gender:',bg= '#e3e6e4')
gender_entry = Entry(add_entry_frame,width='20',borderwidth = '2')

gender_label.grid(row= '2',column = '0')
gender_entry.grid(row= '2',column = '1')


    # Add Entry Button
add_entry_button = Button(add_entry_frame,text='Add Entry',width='10',bg= '#2a49a3',fg= 'white')
add_entry_button.grid(row='3',column = '1',pady = '10')

# Add Entry Message
add_label_message = StringVar()
add_message = Label(add_entry_frame, textvariable= add_label_message)

## DELETE ENTRY FEATURE
delete_entry_frame = Frame(top_frame,bg='yellow',bd='5')
delete_entry_frame.grid(row = '0', column = '1',padx= '20',pady= '20')

    # ID
id_label = Label(delete_entry_frame, text='ID:',bg= '#e3e6e4')
id_entry = Entry(delete_entry_frame,width='20',borderwidth = '2')

id_label.grid(row= '0',column = '0')
id_entry.grid(row= '0',column = '1')

    # Delete Entry Button
delete_entry_button = Button(delete_entry_frame,text='Delete Entry',width='10',bg= '#2a49a3',fg= 'white')
delete_entry_button.grid(row='1',column = '1',padx= '20',pady= '20')


root.mainloop()

Below is the output that I have and the output that I want (I set the frames in different colors so it can easily be distinguised from each other).

You need to change from .grid to .place to make it more easy This is the code:

from tkinter import *
from tkinter import ttk



root = Tk()
root.geometry('800x800')
root.resizable(False, False)

top_frame = Frame(root, bg='#e3e6e4')
top_frame.place(rely=0.1, relx=0.5, anchor=CENTER)


user_columns = ('id', 'name', 'age', 'gender')
table = ttk.Treeview(root, columns=user_columns, show='headings', height='6')
table.place(rely=0.5, relx=0.5, anchor=CENTER)


table.heading('id', text='ID')
table.heading('name', text='Name')
table.heading('age', text='Age')
table.heading('gender', text='Gender')


add_entry_frame = Frame(top_frame, bg='blue', bd='5')
add_entry_frame.grid(row='0', column='0', padx='20', pady='20')


name_label = Label(add_entry_frame, text='Name:', bg='#e3e6e4')
name_entry = Entry(add_entry_frame, width='20', borderwidth='2')

name_label.grid(row='0', column='0')
name_entry.grid(row='0', column='1')


age_label = Label(add_entry_frame, text='Age:', bg='#e3e6e4')
age_entry = Entry(add_entry_frame, width='20', borderwidth='2')

age_label.grid(row='1', column='0')
age_entry.grid(row='1', column='1')


gender_label = Label(add_entry_frame, text='Gender:', bg='#e3e6e4')
gender_entry = Entry(add_entry_frame, width='20', borderwidth='2')

gender_label.grid(row='2', column='0')
gender_entry.grid(row='2', column='1')


add_entry_button = Button(
    add_entry_frame, text='Add Entry', width='10', bg='#2a49a3', fg='white')
add_entry_button.grid(row='3', column='1', pady='10')

add_label_message = StringVar()
add_message = Label(add_entry_frame, textvariable=add_label_message)


delete_entry_frame = Frame(top_frame, bg='yellow', bd='5')
delete_entry_frame.grid(row='0', column='1', padx='20', pady='20')


id_label = Label(delete_entry_frame, text='ID:', bg='#e3e6e4')
id_entry = Entry(delete_entry_frame, width='20', borderwidth='2')

id_label.grid(row='0', column='0')
id_entry.grid(row='0', column='1')

delete_entry_button = Button(
    delete_entry_frame, text='Delete Entry', width='10', bg='#2a49a3', fg='white')
delete_entry_button.grid(row='1', column='1', padx='20', pady='20')


root.mainloop()

The output is this
