将html的表格转换excel的表格；此种方法适应于设置各种单元格的显示，合并，只需设置html的table，设置css就能导出各式各样的excel模板。

实例如下：

导出一个带表头，表头带颜色，设置字体大小，居中，排版适中；

$dataResult = array();      //todo:导出数据（自行设置） 
$headTitle = "XX保险公司 优惠券赠送记录"; 
$title = "优惠券记录"; 
$headtitle= "<tr style='height:50px;border-style:none;><th border=\"0\" style='height:60px;width:270px;font-size:22px;' colspan='11' >{$headTitle}</th></tr>"; 
$titlename = "<tr> 
               <th style='width:70px;' >合作商户</th> 
               <th style='width:70px;' >会员卡号</th> 
               <th style='width:70px;'>车主姓名</th> 
               <th style='width:150px;'>手机号</th> 
               <th style='width:70px;'>车牌号</th> 
               <th style='width:100px;'>优惠券类型</th> 
               <th style='width:70px;'>优惠券名称</th> 
               <th style='width:70px;'>优惠券面值</th> 
               <th style='width:70px;'>优惠券数量</th> 
               <th style='width:70px;'>赠送时间</th> 
               <th style='width:90px;'>截至有效期</th> 
           </tr>"; 
           $filename = $title.".xls"; 
       $this->excelData($dataResult,$titlename,$headtitle,$filename);
