这个拓展的下拉框分两种，一种比较简单的，像“是”或“否”的，这种，直接定义就好了，但是这种只适合下拉框选项少的，多的不行。
另外一种是属于量大的，像一个下拉框有几十个，几百个的，就需要先把数据存在另外一个表格里面，然后再关联读取。
以下直接上代码：
//导入模板
public function mould()
{
$title = "货品批量导入表格";
$cellName = [
'单品名称', '单品编码', '单品规格', '单品单位',
'网购地址', '单品类别', '固定资产', '专属机构',
'供应商', '总部成本', '校区成本', '供应商报价',
'学员价', '普通价', '小店成本价', '最低转卖价',
];//表头及字段名
$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],//货品类型
['column'=>'G','select_options'=>['是','否']],//固定资产
// ['column'=>'H','select_options'=>$branch],//专属机构
// ['column'=>'I','select_options'=>$supplier],//供应商
];
//引入核心文件
vendor("PHPExcel.PHPExcel");
$objPHPExcel = new \PHPExcel()；
//定义配置
$topNumber = 2;//表头有几行占用
$xlsTitle = iconv('utf-8', 'gb2312', $title);//文件名称
$fileName = $title.date('_Ymd');//文件名称
$cellKey = array(
'A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P'
);
//----------------------------------主表------------------------------------//
