Tkinter 缩小小部件之间的差距

Question

i am sorry if it looks messy but how do i shorten the gap between the entry widget and the label widget called "tag" This is what it looks like right now:

I want the entry box and the word "grade" to stick together.I feel like there is a base distance between the grids so i tried some geometry features but couldn't figure it out

import tkinter as tk
from tkinter import ttk
from tkinter import *


win = tk.Tk()
win.geometry("300x250")
win.title("Gpa Calculator")

def gpa_calc():
    pass

grade1 = tk.DoubleVar()
grade2 = tk.DoubleVar()
grade3 = tk.DoubleVar()
grade4 = tk.DoubleVar()
grade5 = tk.DoubleVar()
grade6 = tk.DoubleVar()


label1 = ttk.Label(win, text="Gpa Calculator",font = ("Times New Roman", 15)).grid(column=1,row=0,pady=0)



label1 = ttk.Label(win, text="Class 1").grid(column=0, row=1,)# Column ve row da degismesi gerekebilir
class1 = ttk.Entry(win, width=12, textvariable=grade1)
class1.grid(column=2, row=1,pady=5)
tag1 = ttk.Label(win, text="Gpa:").grid(column=1, row=1,)

label2 = ttk.Label(win, text="Class 2").grid(column=0, row=2,)
class2 = ttk.Entry(win, width=12, textvariable=grade2)
class2.grid(column=2, row=2,pady=5)
tag2 = ttk.Label(win, text="Gpa:").grid(column=1, row=2,)

label3 = ttk.Label(win, text="Class 3").grid(column=0, row=3,)
class3 = ttk.Entry(win, width=12, textvariable=grade3)
class3.grid(column=2, row=3,pady=5)
tag3 = ttk.Label(win, text="Gpa:").grid(column=1, row=3,)

label4 = ttk.Label(win, text="Class 4").grid(column=0, row=4,)
class4 = ttk.Entry(win, width=12, textvariable=grade4)
class4.grid(column=2, row=4,pady=5)
tag4 = ttk.Label(win, text="Gpa:").grid(column=1, row=4,)

label5 = ttk.Label(win, text="Class 5").grid(column=0, row=5,)
class5 = ttk.Entry(win, width=12, textvariable=grade5)
class5.grid(column=2, row=5,pady=5)
tag5 = ttk.Label(win, text="Gpa:").grid(column=1, row=5,)

label6 = ttk.Label(win, text="Class 6").grid(column=0, row=6,)
class6 = ttk.Entry(win, width=12, textvariable=grade6)
class6.grid(column=2, row=6,pady=5)
tag6 = ttk.Label(win, text="Gpa:").grid(column=1, row=6,)

Answer 1

The top label is defining the width of the center column. One way to solve this is to give that top label all 3 columns:

label1 = ttk.Label(win, text="Gpa Calculator",font = ("Times New Roman", 15))
label1.grid(column=0,row=0,pady=0,columnspan=3)

Another good way to solve this is to make a dedicated Frame for the table, so that the Frame has it's own grid. Then you can put that Frame in another grid as a single object.

Answer 2

I'm not a pro, but can you delete paddings and use win.columnconfigure and win.rowconfigure to set cell by cell (or a list of cells) settings of the grid like this:

win.columnconfigure(col,weight=1) 

: weight makes a column or row stretchable. (You can set pad, too )
