动态创建DataTable和Table

DataTable是在System.Data命名空间下面的类，用来以表格的形式存放数据，下面是动态创建并赋值的代码

DataTable dt = new DataTable();
//添加列
                        DataColumn Title = new DataColumn("Title", typeof(string));
                        DataColumn TitleLink = new DataColumn("TitleLink", typeof(string));
                        dt.Columns.Add(Title);
                        dt.Columns.Add(TitleLink);
//添加行数据      
                  foreach (SPListItem item in items)
                        {
                            DataRow row = dt.NewRow();
                            row[Title] = item.GetFormattedValue("Title");
                            row[TitleLink] = SiteName + "/" + WebName + "/" + web.Lists[ListName].RootFolder + 
                                "/" + "DispForm.aspx?ID=" +
                                item.GetFormattedValue("ID") +
                                "&Source=" + SiteName + "/" + WebName + "/"; ;
                            dt.Rows.Add(row);
                        }

Table是一种用来布局的控件，分为html和server两种，html静态的就是写html代码，很好办，server的要动态的用c#代码来创建和赋值，下面是一段示例代码

private Table createTable()
        {
            Table table = new Table();
            TableRow tr1 = new TableRow();

            TableCell cell11 = new TableCell();
            cell11.Text = "公告标题";
            tr1.Cells.Add(cell11);

            TableCell cell12 = new TableCell();
            TextBox bulletinTitle = new TextBox();
            bulletinTitle.ID = "bulletinTitle";
            bulletinTitle.Text = "";
            cell12.Controls.Add(bulletinTitle);
            tr1.Cells.Add(cell12);

            TableCell cell13 = new TableCell();
            cell13.Text = "公告发布时间";
            tr1.Cells.Add(cell13);

            TableCell cell14 = new TableCell();
            DateTimeControl bulletinReleaseDTBegin = new DateTimeControl();
            bulletinReleaseDTBegin.ID = "bulletinReleaseDT";
            bulletinReleaseDTBegin.DateOnly = true;
            cell14.Controls.Add(bulletinReleaseDTBegin);
            tr1.Cells.Add(cell14);

            TableCell cell15 = new TableCell();
            cell15.Text = "公告过期时间";
            tr1.Cells.Add(cell15);

            TableCell cell16 = new TableCell();
            DateTimeControl bulletinExpireDTBegin = new DateTimeControl();
            bulletinExpireDTBegin.DateOnly = true;
            bulletinExpireDTBegin.ID = "bulletinExpireDTBegin";
            cell16.Controls.Add(bulletinExpireDTBegin);
            tr1.Cells.Add(cell16);

            TableCell cell17 = new TableCell();
            Button btnQuery = new Button();
            btnQuery.ID = "btnQuery";
            btnQuery.Text = "查询";
            cell17.Controls.Add(btnQuery);
            tr1.Cells.Add(cell17);

            table.Rows.Add(tr1);

            TableRow tr2 = new TableRow();

            TableCell cell21 = new TableCell();
            cell21.Text = "公告内容";
            tr2.Cells.Add(cell21);

            TableCell cell22 = new TableCell();
            TextBox bulletinContent = new TextBox();
            bulletinContent.ID = "bulletinContent";
            bulletinContent.Text = "";
            tr2.Cells.Add(cell22);

            TableCell cell23 = new TableCell();
            cell23.Text = "到";
            tr2.Cells.Add(cell23);

            TableCell cell24 = new TableCell();
            DateTimeControl bulletinReleaseDTEnd = new DateTimeControl();
            bulletinReleaseDTEnd.ID = "bulletinReleaseDTEnd";
            bulletinReleaseDTEnd.DateOnly = true;
            cell24.Controls.Add(bulletinReleaseDTEnd);
            tr1.Cells.Add(cell24);

            TableCell cell25 = new TableCell();
            cell25.Text = "到";
            tr2.Cells.Add(cell25);

            TableCell cell26 = new TableCell();
            DateTimeControl bulletinExpireDTEnd = new DateTimeControl();
            bulletinExpireDTEnd.DateOnly = true;
            bulletinExpireDTEnd.ID = "bulletinExpireDTEnd";
            cell26.Controls.Add(bulletinExpireDTEnd);
            tr1.Cells.Add(cell26);

            TableCell cell27 = new TableCell();
            cell27.Text = "";
            tr1.Cells.Add(cell27);

            table.Rows.Add(tr2);

            return table;
        }

 protected void Page_Load(object sender, EventArgs e)
        {
            createTable();
            this.form1.Controls.Add(table);
        }
