สร้าง table เพื่อกรอกข้อมูลโดยกำหนด row & column เองต้องใช้อะไรบ้างคะ

Public Class Form1
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Private Sub save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles save.Click
        Dim xbegin1 = xbegin.Value
        Dim xend1 = xend.Value
        Dim ybegin1 = ybegin.Value
        Dim yend1 = yend.Value

        Dim xrange = xend1 - xbegin1 + 1
        Dim yrange = yend1 - ybegin1 + 1


        Dim dgv As New DataGridView
        dgv.Width = 550
        dgv.Height = 310
        dgv.BackgroundColor = Color.White
        dgv.AllowUserToAddRows = False

        For cc As Integer = xbegin1 To xend1
            Dim nc As New DataGridViewTextBoxColumn
            nc.Name = cc.ToString
            dgv.Columns.Add(nc)
        Next

        dgv.Rows.Add(yrange)

        Me.Controls.Add(dgv)

    End Sub
End Class
