我的模型如下所示：
我想要实现的是，不是让行详细信息以默认方式显示，而是希望它们与父网格列对齐显示。我希望详细信息网格跳过前 3 列（为空白)，然后将详细信息与父行的“街道名称”、“街道编号”列对齐。
如果有人能指出我应该研究实现这一目标的属性，那就太好了。
更新：我取得了一些进展，但仍然没有完全通过。我的行显示了我想要的方式，但是在调整列大小时它会中断。我没有发现任何与 Column width changed 或类似的事件相关来编写代码来调整宽度。它是如何在 WPF 中完成的？另外，有没有更好的方法来实现这一点？

private List<Customer> GetCustomers()

}
public List<Customer> Customers { get; set; }
