输入效果表格

“”"

show_frame = tk.Frame()
show_frame.pack(fill=tk.BOTH)

1. 创建字段

columns = ("title", "siteName", "lowerPrice", "lowerDate", 'currentPrice')
columns_value = ('商品', '商城', '最低价', '最低价日期', '当前价')

2. 创建表格对象

tree_view = ttk.Treeview(show_frame, show="headings", columns=columns, height=1)

3. 给表格添加字段名

tree_view.column('title', width=80, anchor='center')
tree_view.column('siteName', width=80, anchor='center')
tree_view.column('lowerPrice', width=80, anchor='center')
tree_view.column('lowerDate', width=80, anchor='center')
tree_view.column('currentPrice', width=80, anchor='center')

4. 设置字段在页面上显示的内容

tree_view.heading('title', text='商品')
tree_view.heading('siteName', text='商城')
tree_view.heading('lowerPrice', text='最低价')
tree_view.heading('lowerDate', text='最低价日期')
tree_view.heading('currentPrice', text='当前价')

5. 将表格对象布局到页面上

tree_view.pack(fill=tk.BOTH, expand=True)root.mainloop()
