后台代码创建Table

 private void CreateTable(int rownum)
    {
        for (int i = 0; i <=rownum; i++)
        {
            TableRow mytablerow = new TableRow();
            TableCell mycell1 = new TableCell();
            TableCell mycell2 = new TableCell();
            if (i ==0)
            {
                mycell1.Text = "Selection";
                mycell2.Text = "Show (Maximum 40 characters)";
                mycell2.HorizontalAlign = HorizontalAlign.Center;
            }
            else
            {
                mycell1.Text=i.ToString();
                TextBox mytexbox1 = new TextBox();
                mytexbox1.CssClass = "b";
                mycell2.HorizontalAlign = HorizontalAlign.Left;
                mycell2.Controls.Add(mytexbox1);
                mytexbox1.ID = "mytexbox" + i.ToString();
                mycell2.VerticalAlign = VerticalAlign.Bottom;
            }
