网上说将单元格格式设置为文本格式就行了，但是我用excel导出功能时，刚开始设置B列为文本格式，结果导出后excel表数字还是不正常显示。
需要自己去手动重置才能正常显示，自己也不太清楚原因，琢磨后通过以下两种方式解决。
$objPHPExcel->getActiveSheet(0)->getStyle('B')->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_TEXT);
第一种方法：不知道是不是因为数据本身是字符串的原因，设置格式改为自定义数字类型后可以了。
$objPHPExcel->getActiveSheet(0)->getStyle('B')->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_NUMBER);
第二种方法：在插入数据时设置格式。
$objPHPExcel->setActiveSheetIndex ( 0 )->setCellValueExplicit('B'.($i + 1),$orders['order_list'][$i-1]['order_sn'],PHPExcel_Cell_DataType::TYPE_STRING);
以下是具体代码：
require_once ‘includes/Classes/PHPExcel.php’;
require_once ‘includes/Classes/PHPExcel/Writer/Excel5.php’;
require_once ‘includes/Classes/PHPExcel/Writer/Excel.php’;
require_once ‘includes/Classes/PHPExcel/IOFactory.php’;
