/**

function  excelExport( $fileName  =  '' ,  $headArr  = [],  $data  = []) {

    $objPHPExcel  =  new  \PHPExcel();
    $objPHPExcel ->getProperties();
    $key  = ord( "A" );  // 设置表头
    foreach  ( $headArr  as  $v ) {
        $colum  =  chr ( $key );

        $key  += 1;

    $column  = 2;
    $objActSheet  =  $objPHPExcel ->getActiveSheet();

            $objActSheet ->setCellValue( chr ( $span ) .  $column ,  $value );
            $span ++;
        }
        $column ++;
    }
    $fileName  = iconv( "utf-8" ,  "gb2312" ,  $fileName );  // 重命名表
    $objPHPExcel ->setActiveSheetIndex(0);  // 设置活动单指数到第一个表,所以Excel打开这是第一个表
    header( 'Content-Type: application/vnd.ms-excel' );
    header( "Content-Disposition: attachment;filename='$fileName'" );
    header( 'Cache-Control: max-age=0' );
    $objWriter  = \PHPExcel_IOFactory::createWriter( $objPHPExcel ,  'Excel5' );
    $objWriter ->save( 'php://output' ); // 文件通过浏览器下载
    exit ();
