    $Form = New-Object System.Windows.Forms.Form
$Form.Size = New-Object System.Drawing.Size(600,400)
$DataGridView = New-Object System.Windows.Forms.DataGridView
$DataGridView.Location =  New-Object System.Drawing.Point(5,25)
$DataGridView.Size = New-Object System.Drawing.Size(565,410)
$DataGridView.ColumnHeadersHeight = 30
$DataGridView.RowHeadersWidth = 1
$col1 = New-Object System.Windows.Forms.DataGridViewTextboxColumn
$col1.Name = 'Col1'
$col1.Width = 50
$DataGridView.Columns.Add($col1)
$col2 = New-Object System.Windows.Forms.DataGridViewTextboxColumn
$col2.Name = 'Col2'
$col2.Width = 50
$DataGridView.Columns.Add($col2)
$Form.Controls.Add($DataGridView)

    I mean that I do not want the row headers show up so I try to use $DataGridView.RowHeadersWidth = 1

    but the row headers on the left side of DataGridView is still there. If I set it to 0, I got error.

    The link I posted tells you exactly how to hide all headers; row and column.

    You can also find all f the properties that control the grid here: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.datagridview?view=netframework-4.7.2

    When trying to use any control in forms it is always best to start with the documentation.

    Here is the better way to build a form. You MUST add the assembly if it is going to run from a PS1 file.

    Add-Type -AssemblyName System.Windows.Forms

$form = New-Object System.Windows.Forms.Form
$form.Size = '600, 400'
$form.StartPosition = 'CenterScreen'

$dataGridView = New-Object System.Windows.Forms.DataGridView
$form.Controls.Add($dataGridView)
$dataGridView.Location = '5, 25'
$dataGridView.Size = '565, 410'
$dataGridView.RowHeadersVisible = $false

$col1 = New-Object System.Windows.Forms.DataGridViewTextboxColumn
$dataGridView.Columns.Add($col1)
$col1.Name = 'Col1'
$col1.Width = 50

$col2 = New-Object System.Windows.Forms.DataGridViewTextboxColumn
$dataGridView.Columns.Add($col2)
$col2.Name = 'Col2'
$col2.Width = 50

$form.ShowDialog()

    A DGV can autoload objects and auto-generate columns so it is not always necessary to create them.

    # example of auto generate grid
    Add-Type -AssemblyName System.Windows.Forms

$form = New-Object System.Windows.Forms.Form
$form.Size = '600, 400'
$form.StartPosition = 'CenterScreen'

$dataGridView = New-Object System.Windows.Forms.DataGridView
$form.Controls.Add($dataGridView)
$dataGridView.Dock = 'Fill'
$dataGridView.RowHeadersVisible = $false

[System.Collections.ArrayList]$files = Get-ChildItem -file | Select Name, Length, CreationTime
$dataGridView.DataSource = $files

$form.ShowDialog()
