winforms - 如何使用 Powershell 合并 DataGridView 中的单元格

Question

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 的好方法。我目前正在使用 DataGridView 并尝试着迷于视觉属性 - 具体来说，我想知道是否有一种方法可以合并单元格，以便我可以制作“子标题”来反射(reflect)与我的树中的哪个父节点相关联选定的 child 。如果这没有多大意义，我想要完成的任务如下所示:

有没有办法合并和居中单元格，或者至少有办法删除某些单元格上的网格线以实现所描绘的鲑鱼色行效果？

这个person还有这个other person尽管 PowerShell 解决方案不容易翻译，但也提出了类似的问题。

不带树功能的基本代码如下(改编自 technet post ):

function Get-ProcessInfo { 
    $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() 
}

This描述如何实现“这两个事件的处理程序，以提供渐变选择背景和一些跨多列的自定义前景内容。”

为了回答这个问题，我浏览了文档 here 。 Microsoft 文档并不总是深入探讨如何使用 API，但当深入探讨时，就值得一读，就像本例中的情况一样。
