WPF SharedSizeGroup调整不正确

Question

在我的应用程序中，我有两个classs DataObj和SubDataObj。对于这两个类，我想创建一个ListView，在其中可以编辑两个类的对象。 DataObj持有List<SubDataObj>，并且某些数据修改会对SubDataObj属性产生影响。

我的方法是像这样构建我的UI：

结构如下：

但是我无法对齐视图的三个部分的边界，也无法弄清楚我在做什么错。

父网格具有Grid.IsSharedSizeScope="True"和所有ColumnDefinitions，Grid中的那些代表headers，ListView.DataTemplate中的那些使用SharedSizeGroup="xxx"。

我的XAML代码看起来像这样：
