一.grid()的使用
在学习grid之前，先引用一个知识点：窗口和坐标系；如图所示：

注：窗口的x,y只有正半轴，所以控件位置(x,y)任何一个小于0，控件就会显示不全或不显示

注意：grid()与pack()函数不一样，grid()函数内必须有参数，且在一个代码文件里不能同时存在grid

和pack，不然会报错

1.堆叠用法

import tkinter as tk    #导入tkinter模块
root = tk.Tk()    #创建窗口

num = 1
for i in range(5):
         for j in range(5):
                  label_1 = tk.Label(root,text = f"标签{num}   ")
                  label_1.grid(row = i,column = j)
                                 #行      #列
                  num += 1

root.mainloop()    #消息循环

运行：

它和pack的区别：pack从窗口坐标((长-标签长)/2,0)开始的,但grid从(0,0)开始的

grid(row = 横排个数,column = 竖排个数)

如图所示：

假如我想找”标签17“的row和column值，就可以按照这个表：

取得"标签17" 的row和column值为(1,3)

注意：row和column用法不会随窗口变化而变化，它只跟所堆叠的控件有关

2.合并用法

import tkinter as tk    #导入tkinter模块
root = tk.Tk()    #创建窗口

num = 1
for i in range(5):
         for j in range(5):
                  label_1 = tk.Label(root,text = f"标签{num}   ")
                  label_1.grid(row = i,column = j,rowspan = 5,columnspan = 5)
                  num += 1

root.mainloop()    #消息循环

运行：

grid(rowspan = 在x轴上合并控件的个数,columnspan = 在y轴上合并控件的个数)

注意：rowspan和columnspan 都是正整数，不然会报错

(其实作者也不知道这到底有嘛用[dogs])

其他函数如：ipadx，ipady，pads，pady和pack()一样
