DataTable动态展示数据
1.后台UI类:
    @Priv
    public void getDataTable(DataGridAction dga){
        String tableID = $V("TableID");
        DataTable dt = YearBookBL.getDataTable(tableID);
        Current.put("_CurentDT", dt);
        Response.put("Columns", dt.getDataColumns());
        dga.bindData(dt);
    }
    把DataTable中的所有列放到Response中以供前台去获取动态表头

2.前台页面:
<z:datagrid id="dg1" method="YearDataManage.getDataTable">
    <table width="100%" cellpadding="2" cellspacing="0" class="z-datagrid">
        <tr ztype="head" class="dataTableHead">
            <td width="5%" ztype="RowNo"><z:lang id="Common.SN">序号</z:lang></td>
            <td width="4%" ztype="selector" field="ID">&nbsp;</td>
            <z:foreach data="${Columns}">
                <td>${value.ColumnName}</td>
            </z:foreach>
        </tr>
        <tr onDblClick="" class1="dg_tr_odd" class2="dg_tr_even">
            <td>&nbsp;</td>
            <td>&nbsp;</td>
            <z:foreach data="${_Zving_ZList_Data[i-1]}" count="${length(Columns)}" >
                <td>${value}</td>
            </z:foreach>
        </tr>
    </table>
</z:datagrid>
    1).遍历Columns,动态获取表头
    2)._Zving_ZList_Data 是ListTag标签内部静态属性,用于指定DataTable变量,该变量同时也被添加到DataGrid和DataList标签中
    3).遍历_Zving_ZList_Data[i-1],获取dt中每一个单元格中所对应的值,length(Columns)限制列数,去掉了行号那一列
