wpf - 数据网格，合并/组合行、单元格和列

Question

我正在尝试准确完成 this 问题所要求的内容，但不幸的是，作为答案提供的代码示例已经消失，而且我也没有使用 WPF Toolkit，这里是他提出的问题:

I am trying to Merge cells in WPF toolkit datagrid .I am trying to do something as shown in the image below.We can do this in Winforms datagrid.But how to do this using WPF toolkit datagrid ?.Or is there any alternative controls..?

Can we do this using listview or listbox..? Or is there any free controls available which have this functionality ?

我找到了几个设法使用 DataGridView 控件执行此操作的答案，但我不想在 WPF 项目中使用 Form 对象，有没有办法完成此操作？
