迭代DataGridView仅获取前两列的值

# 导入所需的库
import tkinter as tk
from tkinter import ttk

# 创建一个示例的DataGridView
data = [
    ['John', 'Doe', 'john.doe@example.com', 'Male'],
    ['Jane', 'Smith', 'jane.smith@example.com', 'Female'],
    ['Bob', 'Johnson', 'bob.johnson@example.com', 'Male']
]

# 创建一个窗口
window = tk.Tk()

# 创建一个DataGridView
datagrid = ttk.Treeview(window, columns=('Column 1', 'Column 2', 'Column 3', 'Column 4'))
datagrid.heading('#0', text='Index')
datagrid.heading('Column 1', text='First Name')
datagrid.heading('Column 2', text='Last Name')
datagrid.heading('Column 3', text='Email')
datagrid.heading('Column 4', text='Gender')

# 插入数据到DataGridView
for i, row in enumerate(data):
    datagrid.insert('', 'end', text=str(i), values=row)

# 获取DataGridView的行数和列数
num_rows = len(datagrid.get_children())
num_cols = len(datagrid['columns'])

# 迭代每一行
for row_id in range(num_rows):
    # 迭代前两列
    for col_id in range(2):
        # 获取单元格的值
        cell_value = datagrid.item(datagrid.get_children()[row_id], 'values')[col_id]
        print(f"Value at row {row_id}, column {col_id}: {cell_value}")

# 运行窗口主循环
window.mainloop()
