PHPExcel导出 适配多个模板

**
首先用composer在项目里安装phpexcel在composer.json require里加入 “moonlandsoft/yii2-phpexcel”，然后composer update即可
**
1.这里在项目里先创建个工具类common/utils/Exportfile.php，用该类实现导出，其他类调用该类的exportExcel方法即可，

getActiveSheet()->getStyle('A1:'.$x.($y))->applyFromArray([
            'borders' => [
                'allborders' => [
                    'style' => \PHPExcel_Style_Border::BORDER_THIN,//粗的是thick
                ]
            ]
        ]);

//设置表格样式(背景颜色和边框线)
        if(!empty($paramenterHeight)&&  is_array($paramenterHeight)){
            foreach ($paramenterHeight as $rownum => $value){
                $rownum = $rownum + 1;
