以下是我自己的实现方法，可能存在很多不足，欢迎大家提出改进...  
实现步骤：  
一：去官网 [http://phpexcel.codeplex.com/][http_phpexcel.codeplex.com]下载最新PHPExcel放到Vendor下，注意位置：ThinkPHP\\Extend\\Vendor\\PHPExcel\\PHPExcel.php。  
二：在CommonAction.class.php中添加以下两个函数：

使用方法

导入：

function impUser(){
             if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
                $result = $this->importExecl($_FILES["import"]["tmp_name"]);
                if($result["error"] == 1){          
                  $execl_data = $result["data"][0]["Content"];
                          foreach($execl_data as $k=>$v){
                              ..这里写你的业务代码..
                          }
                 }
              }
        }

导出：

function expUser(){//导出Excel
                $xlsName  = "User";
                $xlsCell  = array(
                    array('id','账号序列'),
                    array('account','登录账户'),
                    array('nickname','账户昵称')
                );
                $xlsModel = M('Post');
                $xlsData  = $xlsModel->Field('id,account,nickname')->select();
                $this->exportExcel($xlsName,$xlsCell,$xlsData);
            }
