今天老师给我们讲解了前些天我们学习上的一些漏洞，也就是给我们查漏补缺、、、

主要讲了一下几点：

在这里着重讲一下动态生成表格吧。

在页面中添加三个按钮    分别用不同的方式来添加表格

BUTTON1 按钮，完成了添加HTML表格的操作

 protectedvoid Button1_Click(object sender, EventArgs e)
    {
        HtmlTable table = newHtmlTable();  //表格创建完成
        for (int i = 0; i < 5; i++) //控制行
        {
            HtmlTableRowrow = new HtmlTableRow();
            for (int j =0; j < 5; j++)  //控制单元格
            {
               HtmlTableCell cell = new HtmlTableCell();

               HtmlTable t1 = new HtmlTable();
               HtmlTableRow r = new HtmlTableRow();
               HtmlTableCell c = new HtmlTableCell();
               c.InnerText = "aaaaaaaaaaaaa";
               r.Cells.Add(c);
               t1.Rows.Add(r);
               cell.Controls.Add(t1);

               //cell.InnerHtml = string.Format("i:{0};j:{1}", i, j);
               row.Cells.Add(cell);
            }
           table.Rows.Add(row);
        }
        this.Controls.Add(table);
    }

BUTTON2完成了添加WEB服务器控件的表格
    protected void Button2_Click(object sender, EventArgs e)
    {
        Table t = new Table();
        for (int i = 0; i < 3; i++)
        {
            TableRow row= new TableRow();
            for (int j =0; j < 2; j++)
            {
               TableCell cell = new TableCell();
               Button btn = new Button();
               btn.Text = i.ToString() + j.ToString();
               cell.Controls.Add(btn);
               row.Cells.Add(cell);
            }
            t.Rows.Add(row);
        }
        this.Panel1.Controls.Add(t);

   }

BUTTON3按钮，完成了添加DataTable表格的操作
    protected void Button3_Click(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        DataColumn dc = new DataColumn();
        dc.ColumnName = "id";
        dc.DataType = typeof(int); //Type.GetType("System.Int32");
        dc.AllowDBNull = false;
        dc.AutoIncrement = true;
        dc.AutoIncrementSeed = 1;
        dc.AutoIncrementStep = 1;
        dt.Columns.Add(dc);
        dc = new DataColumn();
        dc.ColumnName = "name";
        dc.DataType = typeof(string);
        dc.AllowDBNull = false;
        dt.Columns.Add(dc);
        DataRow row = dt.NewRow();
        row["name"] ="zhangsan";
        dt.Rows.Add(row);
        this.DropDownList1.DataSource = dt;
        this.DropDownList1.DataTextField ="name";
        this.DropDownList1.DataValueField ="id";
        this.DropDownList1.DataBind();
    }
