PHP编程：PHP使用PHPExcel删除Excel单元格指定列的方法

/**
* @Author:   HTL
* @Description: 移出单元列
* @objPHPExcel: phpexecel object
* @remove_columns:要移出的列
*/
function _remove_column($objPHPExcel,$remove_columns){
    if(!$objPHPExcel
      || !is_object ($objPHPExcel)
      || !$remove_columns
      || !is_array($remove_columns)
      || count($remove_columns)<=0) return ;
    //单元格模板值,用于匹配要删除的列(在excel模板第一列)
    $cell_val = '';
    //单元格总列数
    $highestColumm = $objPHPExcel->getActiveSheet()->getHighestColumn();
    for ($column = 'A'; $column <= $highestColumm;) {
      //列数是以A列开始
      $cell_val = $objPHPExcel->getActiveSheet()->getCell($column."1");
      $cell_val = preg_replace("/[\s{}]/i","", $cell_val);
      //移出没有权限导出的列
      //移出后column不能加1,因为当前列已经移出加1后会导致删除错误的列
      //此问题浪费了几十分钟
      if(strlen($cell_val)>0 && in_array($cell_val,$remove_columns))
      {
        $objPHPExcel->getActiveSheet()->removeColumn( $column);
      }
      else
      {
        $column++;
      }
    }
}
//example
//导入PHPExcel类
vendor("PHPExcel.PHPExcel");
$filepath = './data/upload/temp.xlsx';
$objReader = \PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($filepath);
$this->_remove_column($objPHPExcel,array("age","address"));
