tkinter Treeview：使用标记和配置的标记更改Treeview中的偶数行和奇数行颜色根本不起作用

Question

我一直很难找到我的解决方案，其中tags和tag.configured无法改变我的oddrow和evenrow背景色，以便轻松查看库存列表中的行，即使我复制了示例代码，但仍然无法为我工作。为了进一步了解问题，以下是我们遇到问题的代码部分：

    for record in records:
        #print(sorted(str(record[0]), reverse=False))
        col_head.insert("", "end", text=record, values=(record[0], record[1], record[2], record[3], record[4], record[5]), tags=('ODDROW'))
        col_head.tag_configure('ODDROW', background='gray')

当执行时

清单中的Treeview甚至不会显示任何灰色背景或我试图在tag_配置中输入的其他颜色，如果您想查看整个程序，请看这里

顺便说一下，我是python新手，最近学习了tkinter和一些东西。因此，我们非常感谢您的任何帮助和建议

顺便说一下，这段代码需要一个db，如果您要运行程序Inventory_table.db，文件就在这里

再次提前感谢您的帮助

另外，我使用Python3.8作为Pycharm的IDE的项目解释器
