今天上午在论坛中的ASP.NET版块中看到一位网友询问GridView固定表头表列的问题，正好闲着没事，写了一段：

    Dim i As Integer = 0
    While i < 50
      Dim rd As System.Random = New System.Random(Environment.TickCount * i)

      dr = dt.NewRow
            dr(0) = "BCCN论坛" + i.ToString
            dr(1) = "不说也罢" + i.ToString

      dr(5) = System.Math.Round(rd.NextDouble * 100, 2)
      dt.Rows.Add(dr)
      System.Math.Min(System.Threading.Interlocked.Increment(i), i - 1)
    End While
    Dim dv As System.Data.DataView = New System.Data.DataView(dt)
    Return dv
  End Function

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    If Not IsPostBack Then
      GridView1.Attributes.Add("style", "table-layout:fixed")
      GridView1.DataSource = CreateDataSource()
      GridView1.DataBind()
    End If
  End Sub

<script type="text/javascript">
function settable()

var tl = document.getElementById("<%=GridView1.ClientID%>");
var t2 = tl.cloneNode(true)

t2.deleteRow(i)
tl.deleteRow(0)
a.appendChild(t2)
}
window.onload = settable

希望能抛砖引玉。
