尝试在vb.net中创建网格视图，并且每次在第一行上覆盖新行时，请帮助我使用此代码plz

' 引入必要的命名空间
Imports System.Windows.Forms

Public Class MainForm
    Inherits Form

    Private gridView As DataGridView

    Public Sub New()
        ' 初始化窗体
        Me.Text = "网格视图示例"
        Me.Size = New Size(600, 400)

        ' 创建网格视图控件
        gridView = New DataGridView()
        gridView.Dock = DockStyle.Fill
        Me.Controls.Add(gridView)

        ' 设置网格视图属性
        gridView.AllowUserToAddRows = False ' 禁止自动添加新行
        gridView.RowHeadersVisible = False ' 隐藏行标头

        ' 创建表格列
        Dim column1 As New DataGridViewTextBoxColumn()
        column1.HeaderText = "姓名"
        gridView.Columns.Add(column1)

        Dim column2 As New DataGridViewTextBoxColumn()
        column2.HeaderText = "年龄"
        gridView.Columns.Add(column2)

        Dim column3 As New DataGridViewTextBoxColumn()
        column3.HeaderText = "性别"
        gridView.Columns.Add(column3)

        ' 添加初始行数据
        Dim row As New DataGridViewRow()
        row.CreateCells(gridView, "张三", "25", "男")
        gridView.Rows.Add(row)

        ' 添加按钮，用于在第一行上覆盖新行
        Dim addButton As New Button()
        addButton.Text = "添加新行"
        addButton.Location = New Point(10, 10)
        Me.Controls.Add(addButton)

        ' 绑定按钮点击事件
        AddHandler addButton.Click, AddressOf AddNewRow

    End Sub

    Private Sub AddNewRow(sender As Object, e As EventArgs)
        ' 创建新行数据
        Dim newRow As New DataGridViewRow()
        newRow.CreateCells(gridView, "新行", "18", "女")

        ' 在第一行上覆盖新行
        gridView.Rows.Insert(0, newRow)

        ' 移除最后一行
        gridView.Rows.RemoveAt(gridView.Rows.Count - 1)
    End Sub

End Class

' 启动应用程序
Public Sub Main()
    Application.Run(New MainForm())
End Sub
