这次跟大家聊聊j如何用PHP自定义Excel的导出及合并单元格,下面就是实战案例,一起来看一下。

首先自定义导出,我用的是一个下拉多选框的一个插件,百度一下就可找到,为了样式好看。如图

value值对应的是你数据库中查出的字段值,text对应的是你的表头信息。ok,然后我是通过GET把这俩个值传到我们控制器的。

引入导出类,这个就不多说。

然后就是查询数据库,把数据处理成一个二维数组,进行循环遍历输出在表格中

我的数据格式是1对多的关系,一个班主任对应多个班级,那么我要在表格中合并这个班主任,$count是对班级的统计,当班主任

对应的班级数量>1时,才合并。

            $str=$_GET['str'];//勾选
            $str2=$_GET['str2'];//表头
            $td_field=explode(',', $str2);//表头
            $field=explode(',', $str);//勾选
            $objPHPExcel=new \PHPExcel();

            $objPHPExcel->getProperties()->setCreator('http://www.jb51.NET')
                ->setLastModifiedBy('http://www.jb51.Net')
                ->setTitle('Office 2007 XLSX Document')
                ->setSubject('Office 2007 XLSX Document')
                ->setDescription('Document for Office 2007 XLSX, generated using PHP classes.')
                ->setKeywords('office 2007 openxml php')
                ->setCategory('Result file');
            $objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue('A1',$td_field[0])
                ->setCellValue('B1',$td_field[1])
                ->setCellValue('C1',$td_field[2])
                ->setCellValue('D1',$td_field[3])
                ->setCellValue('E1',$td_field[4])
                ->setCellValue('F1',$td_field[5])
                ->setCellValue('G1',$td_field[6])
                ->setCellValue('H1',$td_field[7])
                ->setCellValue('I1',$td_field[8])
                ->setCellValue('J1',$td_field[9])
                ->setCellValue('K1',$td_field[10])
                ->setCellValue('L1',$td_field[11])
                ->setCellValue('M1',$td_field[12]);
            $i=2;
            
            //->mergeCells('A18:E22')合并单元格;->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER) 垂直居中
            foreach($new_array as $k=>$v){
                if($v["count"] > 1){

                    $objPHPExcel->setActiveSheetIndex(0)
                    ->setCellValue('A'.$i,$v["$field[0]"])
                    ->setCellValue('B'.$i,$v["$field[1]"])
                    ->setCellValue('C'.$i,$v["$field[2]"])

                    ->mergeCells('A'.$i.':A'.($i+$v["count"]-1))

                    $objPHPExcel->setActiveSheetIndex(0)->getStyle('A'.$i)->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER);

            //生成xls文件
