Winforms 如何使用Powershell合并DataGridView中的单元格

亲爱的Powershell专家， 我最近发现，将WinForms与PowerShell结合使用是创建小型但真正有用的GUI的一种好方法。我目前正在使用DataGridView，并试图对可视化属性产生兴趣——具体来说，我想知道是否有一种方法可以合并单元格，以便生成“子标题”，反映树中的哪个父节点与选定的子节点相关联。如果这没有多大意义，我试图实现的目标如下所示：

有没有一种方法可以合并单元格并使其居中，或者至少有一种方法可以删除某些单元格上的网格线，以实现所描绘的三文鱼色行效果

尽管PowerShell解决方案不易翻译，但这一点和这一点提出了类似的问题

不带树功能的基本代码如下（改编自）：

这可能吗？

描述了如何实现“两个事件的处理程序，以便提供渐变选择背景和跨越多列的一些自定义前景内容。”

为了回答这个问题，我浏览了一下医生。Microsoft文档并不总是深入讨论如何使用API，但当它这样做时，它值得一读，就像本例中的情况一样

    $array = New-Object System.Collections.ArrayList 
    $Script:procInfo = Get-Process | Select Id,Name,Path,Description | sort -Property Name 
    $array.AddRange($procInfo) 
    $dataGridView1.DataSource = $array 
    $form1.refresh() 
}
