如何为treeview窗口小部件设置样式，以便备用行具有不同的背景颜色，例如，行1,3,5具有白色背景，行2,4,6具有浅蓝灰色背景？
我还想设置gridlines。

几个月前我也有同样的问题。
来自tk docs：
You can assign a list of tags to each item using the "tags"
item configuration option (again, when creating the item or later on).
Tag configuration options can then be specified, which will then
apply to all items having that tag.
基本上，您将一个标记应用于所有奇数行，每个偶数行应用不同的标记，然后配置标记。
在树视图中创建项目时，请为其添加标记：
tree.insert('', 'end', text = 'your text', tags = ('oddrow',))
此代码在tree中创建一个元素，tags参数将元素'oddrow'分配给元素。
使用'oddrow'和'evenrow'标签创建所有元素后，您可以为标记着色：
tree.tag_configure('oddrow', background='orange')
tree.tag_configure('evenrow', background='purple')

我意识到这是一个古老的问题，但仅仅是为了在创建树之后配置标签的记录（即，还没有添加任何项目）也可以。随着项目稍后插入，它们将被赋予适合其“oddrow”或“evenrow”标签的背景颜色。

这是创建一个SQL数据库。然后将少数客户从db加载到列表框中。 然后你可以点击测试新颜色按钮来显示它改变奇数行的颜色。只要您将sqlalchemy安装为模块，这就可以运行。

这是可运行的，没有任何额外的模块......可能会使代码混乱，使其与您自己的代码一起工作。
