求助，关于在网页中显示一个动态表格的问题
我在.aspx.cs里面用C#写好了表格的代码，运行后网页是空的，是不是要在.aspx里面也要写代码啊？？？

在.aspx.cs的部分代码：


protected void Page_Load(object sender, EventArgs e)
  {
//数据库连接没有问题，省略
  string sqlString = "select name,sex,city from student";
  SqlDataAdapter sda = new SqlDataAdapter(sqlString, conn);
  DataSet ds = new DataSet();
  sda.Fill(ds);
  //定义一个表格
  #region
  table.CellPadding = 2;//table在.aspx中定义了
  table.CellSpacing = 0;
  table.Width = 600;
  table.Style.Add("font-size", "12");
  //定义第一行
  TableRow tr1 = new TableRow();
  tr1.BackColor = System.Drawing.ColorTranslator.FromHtml("#CCCCCC");
  tr1.BorderColor = System.Drawing.Color.Blue;
  tr1.BorderStyle = BorderStyle.Solid;
  tr1.BorderWidth = 1;
  tr1.Style.Add("text-align", "center");
  tr1.Style.Add("font-weight", "bold");
  tr1.Height = 25;

  //定义第一行的第一个单元格
  TableCell tc1 = new TableCell();
  tc1.Width = 200;
  tc1.Text = "姓名";
  tc1.BorderColor = System.Drawing.Color.Blue;
  tc1.BorderStyle = BorderStyle.Solid;
  tc1.BorderWidth = 1;
  tr1.Cells.Add(tc1);

  //定义第一行的第二个单元格
  TableCell tc2 = new TableCell();
  tc1.Width = 200;
  tc1.Text = "性别";
  tc1.BorderColor = System.Drawing.Color.Blue;
  tc1.BorderStyle = BorderStyle.Solid;
  tc1.BorderWidth = 1;
  tr1.Cells.Add(tc2);

  //定义第一行的第三个单元格
  TableCell tc3 = new TableCell();
  tc1.Width = 200;
  tc1.Text = "城市";
  tc1.BorderColor = System.Drawing.Color.Blue;
  tc1.BorderStyle = BorderStyle.Solid;
  tc1.BorderWidth = 1;
  tr1.Cells.Add(tc3);
  #endregion
  DataView dv = ds.Tables[0].DefaultView;
  for (int index = 0; index < dv.Count; index++)
  {
  TableRow tr2 = new TableRow();
  tr2.BackColor = System.Drawing.ColorTranslator.FromHtml("#FFFFFF");
  tr2.BorderColor = System.Drawing.Color.Blue;
  tr2.BorderStyle = BorderStyle.Solid;
  tr2.BorderWidth = 1;
  tr2.Style.Add("text-align", "center");
  tr2.Height = 25;

  //定义第一行的第一个单元格
  TableCell tc4 = new TableCell();
  tc4.Width = 200;
  tc4.Text = dv[index]["name"].ToString();
  tc4.BorderColor = System.Drawing.Color.Blue;
  tc4.BorderStyle = BorderStyle.Solid;
  tc4.BorderWidth = 1;
  tr2.Cells.Add(tc4);

  //定义第一行的第二个单元格
  TableCell tc5 = new TableCell();
  tc5.Width = 200;
  tc5.Text = dv[index]["sex"].ToString();
  tc5.BorderColor = System.Drawing.Color.Blue;
  tc5.BorderStyle = BorderStyle.Solid;
  tc5.BorderWidth = 1;
  tr2.Cells.Add(tc5);

  //定义第一行的第二个单元格
  TableCell tc6 = new TableCell();
  tc6.Width = 200;
