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')
