    Sub Main()

        ' Create Datable
        Dim dtTable As DataTable = New DataTable("TableName")

        ' Create Column Header
        dtTable.Columns.Add(New DataColumn("ID", GetType(Integer)))
        dtTable.Columns.Add(New DataColumn("Name", GetType(String)))
        dtTable.Columns.Add(New DataColumn("Email", GetType(String)))

        ' Add Rows
        dtTable.Rows.Add(1, "Name 1", "Email 1")

        ' Add Rows
        For i As Integer = 2 To 10
            dtTable.Rows.Add(i, "Name " & i, "Email " & i)
        Next

        ' Display
        For Each row As DataRow In dtTable.Rows
            Console.WriteLine(String.Format("ID = {0} , Name = {1} , Email = {2}" _
                                            , row.Item("ID") _

                                            , row.Item("Email")))
        Next

        '*** for DataSource
