POI导出EXCEL文档、水平垂直居中、表头添加颜色

如下工具类添加表头颜色、水平垂直居中、设置列宽和行高：

前端HTML页面代码：

<a href="javascript:void(0);" style="display: none;" id="a_exportCode" data-toggle="popover" data-placement="top" ></a>

<a href="javascript:void(0);" style="display: none;" id="a_exportCode" data-toggle="popover" data-placement="top" ></a>

		//导出统计数据function exportCode() {$("#a_exportCode").attr('href','/apiStore/ApiLogManagerAction/exportData?appKey='+$("#app_key").val()+'&start_date='+$("#startDate").val())+"&endDate="+$("#end_date").val()+"&name="+$("#name").val();$("#a_exportCode").attr('download','code'+new Date().getTime()+".pdf");$("#a_exportCode")[0].click();}
