這個拓展的下拉框分兩種，一種比較簡單的，像“是”或“否”的，這種，直接定義就好了，但是這種只適合下拉框選項少的，多的不行。

另外一種是屬於量大的，像一個下拉框有幾十個，幾百個的，就需要先把資料存在另外一個表格裡面，然後再關聯讀取。

以下直接上程式碼：

//匯入模板
  public function mould()
  {
        $title = "貨品批量匯入表格";
        $cellName = [
            '單品名稱', '單品編碼', '單品規格', '單品單位',
            '網購地址', '
 
單品類別', '固定資產', '專屬機構',
            '供應商', '總部成本', '校區成本', '供應商報價',
            '學員價', '普通價', '小店成本價', '最低轉賣價',
        ];//表頭及欄位名

        $branch = M('branch') -> where(['branch_name'=>['NEQ','']]) -> getField('branch_name',true);
        $supplier = M('supplier') -> where(['status'=>1
 
,'supplier_name'=>['NEQ','']]) ->getField('supplier_name',true);
        $goods_type = M('goods_type') -> where(['pid'=>0]) -> getField('type_name',true);


        $spectials = [
//          ['column'=>'F','select_options'=>$goods_type],//貨品型別
            ['column'=>'G','select_options
 
'=>['是','否']],//固定資產
//          ['column'=>'H','select_options'=>$branch],//專屬機構
//          ['column'=>'I','select_options'=>$supplier],//供應商
        ];

        //引入核心檔案
        vendor("PHPExcel.PHPExcel");
        $objPHPExcel = new \PHPExcel()；
        //定義配置
        $topNumber = 2;//表頭有幾行佔用
        $xlsTitle = iconv('utf-8', 'gb2312', $title);//檔名稱
        $fileName = $title.date('_Ymd');//檔名稱
        $cellKey = array(
            'A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P'
        );
        //----------------------------------主表------------------------------------//
