如何在Powershell中启用Datagrid的单元格编辑？

Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing

$form = New-Object System.Windows.Forms.Form
$dataGrid = New-Object System.Windows.Forms.DataGrid
$dataGrid.Dock = 'Fill'
$form.Controls.Add($dataGrid)

$dataTable = New-Object System.Data.DataTable
$dataGrid.DataSource = $dataTable

$dataGrid.ReadOnly = $false
$dataGrid.AllowUserToAddRows = $false
$dataGrid.AllowUserToDeleteRows = $false
$dataGrid.EditMode = 'EditOnKeystrokeOrF2'

$form.ShowDialog()
