导入：前端使用的layui框架

   

                    
                        上传文件
                    
             
             js:
       

 layui.use('upload', function () {

            , url: upload_url //上传接口

##    控制器：

public function collects(Request $request)
{

    $dataNewName = date('Y-m-d-h-i-s') . '.' . $request->file('file')->getClientOriginalExtension();
    $dataPath = Storage::disk('public')->putFileAs('file', $request->file('file'), $dataNewName);
    Excel::import(new EmployeeImport($company_id), $dataPath);
    $error = session('error');
    if (count($error) > 1) {
        $result['code'] = 0;
        $result['msg'] = '上传成功,有失败文件';

    } else {
        $result['code'] = 1;

    }
} else {

}

##EmployeeImport

            //  \Log::info(__FUNCTION__ . ',' . __LINE__ . ',company:' . $this->getCompanyId() . ' - ' . $this->company_id);
        }

                $result = $result->toArray();
                array_walk($result, function ($value, $key) use (&$createR, $sexMap, $tmpFields) {

                            $value = isset($sexMap[$value]) ? $sexMap[$value] : 0;
                        }
                        if ($key == 3) {

                                $value = gmdate('Y-m-d H:i:s', $n);
                            } else {

                            }
                        }
                        if ($key == 14) {
                            $value = $this->company_id;
                        }
                        $createR[$field] = $value;
                    }
                });
                if (count($createR) != 15) {
                    array_push($result, $count);
                    array_push($error, $result);

                    \Log::info(__FUNCTION__ . __LINE__ . ',model:' . json_encode($model));
                } catch (\Exception $e) {
                    array_push($result, $count);
                    array_push($error, $result);
                    continue;
                }
            }
            session(['error' => $error]);
        }
    
    
        /**
         * @return mixed
         */
        public function getCompanyId()
        {
            return $this->company_id;
        }
    
        /**
         * @param mixed $company_id
         */
        public function setCompanyId($company_id)
        {
            $this->company_id = $company_id;
        }
    
    
    }

即可实现laravel excel的导入并插入数据表
##导出
Export

salary_id = $salary_id;
    }

    public function collection()
  {
      $id=session('salary_id');
      $data=[];
      $title = array('收款账号', '收款户名', '省份', '城市', '收款银行', '金额', '用途');
      array_unshift($data, $title);
          $salaries = Salary::where('salary_id',$this->salary_id)->get(['bank_account', 'bankAccount_name', 'province', 'city', 'opening_bank', 'salary', 'remarks'])->toArray();
          foreach ($salaries as $salaries) {
          array_push($data, $salaries);
      }
      return new Collection($data);
  }
}

控制器

public function export(Request $request)
    {
        $salary_id = $request->get('id');
        return Excel::download(new SalaryExportImport($salary_id), '工资表.xlsx');
    }
