Question

我需要什么：

点击导出标签数据从数据库加载到Excel文件中，格式如csv，xls等。

我的问题：

在Excel文件中加载执行文件无数据时。

这是我的代码段：

  error_reporting(E_ALL);
     ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);
    date_default_timezone_set('UTC');

    mysql_connect('localhost','root','') or die('Cannot connect to database !');
    mysql_select_db("atesting_ess") or die('No database found in mysql !');

   if (PHP_SAPI == 'cli')
    die('This example should only be run from a Web Browser');

        /** Include PHPExcel */
     require_once dirname(__FILE__) . '/../Classes/PHPExcel.php';

         // Create your database query
       $query = "SELECT * FROM asana_tasks";  

       // Execute the database query
        $result = mysql_query($query) or die(mysql_error());

       // Instantiate a new PHPExcel object
       $objPHPExcel = new PHPExcel(); 
      // Set the active Excel worksheet to sheet 0
      $objPHPExcel->setActiveSheetIndex(0); 

        $rowCount = 1; 
        while($row = mysql_fetch_array($result)){ 
    //print_r($row);
    $objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue('A'.$rowCount, $row['Projects_name'])
                ->SetCellValue('B'.$rowCount, $row['Name']) 
                 ->SetCellValue('C'.$rowCount, $row['Priority']); 

             $rowCount++; 
           } 
       // Redirect output to a client?s web browser (Excel2007)
     header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
     header('Content-Disposition: attachment;filename="01simple.xlsx"'); 
     header('Cache-Control: max-age=0');
     // If you're serving to IE 9, then the following may be needed
     header('Cache-Control: max-age=1');

// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;

我试过通过添加虚拟数据来解决它的工作精细代码：
```
   // Add some data
     $objPHPExcel->setActiveSheetIndex(0)
    ->setCellValue('A1', 'Hello')
    ->setCellValue('B2', 'world!')
    ->setCellValue('C1', 'Hello')
    ->setCellValue('D2', 'world!');
```
- 工作正常。

Answer 1

由于列是A，B，C等而不是1,2,3等，因此将其转换为字符。下面的代码适用于A到Z列，AA，AB等，这需要扩展。

$columnvalue = strtoupper(chr($col) + 96));
$objPHPExcel->getActiveSheet()->setCellValue($columnvalue . $row, $value);

NO数据使用PHPExcel库加载到Excel文件中
