ASP.NET中UltraWebGrid怎么显示表头

public partial class jsxx_wwjsqd : PageBase
{
    private DataTable dt_go
    {
        get { return (DataTable)ViewState["dt_go"]; }
        set { ViewState.Add("dt_go", value); }
    }
    protected void Page_Load(object sender, EventArgs e)
    {
        this.InitGridHead();
        tablehead();
        if (!IsPostBack)
        {
            lbl_PageSize.Value = "100";
            lbl_PageCount.Text = "0";
            lbl_PageIndex.Text = "1";
            lbl_Page_Count.Text = "0";
            BindPage(dt_go, 1);
        }
    }

    //初始化　UltraWebGrid2标头
    private void InitGridHead()
    {
        listTableInfo.Clear();
        listTableInfo.Add(new TableInfo("OrderBy_ShortName", "料号", "200px", HorizontalAlign.Left, ColumnType.NotSet, "", false));

        UltraWebGrid2.DisplayLayout.Bands[0].HeaderLayout.Add(ch);   //增加到列头集合中
    }

怎么在修改以上的代码才能显示出图片中的表头格式
