如何使用网格将HTML表导出到Excel

Question

我非常擅长将表格/数据导出到Excel或PDF。但到目前为止，我已经编写了用于将HTML表格导出到Excel（xls）的jQuery。问题是它没有显示excel的网格。以下是Excel中输出的示例。

以下是我要导出的代码：

$(document).ready(function() {
  $("#btnExport").click(function(e) {
    e.preventDefault();

    //getting data from our table
    var data_type = 'data:application/vnd.ms-excel';
    var table_div = document.getElementById('table_id');
    var table_html = table_div.outerHTML.replace(/ /g, '%20');

    var a = document.createElement('a');
    a.href = data_type + ', ' + table_html;
    a.download = 'exported_salmon_' + Math.floor((Math.random() * 9999999) + 1000000) + '.xls';
    a.click();
  });
});

这是我的HTML

<table  id="table_id" class="data-table">
<caption class="title">Sales Salmon Usage Per 1K</caption>
<thead>
  <tr>
    <th><center>NO</center></th>
    <th><center>OUTLET</center></th>
    <th><center>DATE</center></th>
    <th><center>SALES</center></th>
    <th><center>USAGE</center></th>
    <th><center>USAGE PER 1K</center></th>
  </tr>
</thead>
<tbody>

$store_name=$_POST['storename'];

  $date11 = strtotime($date1);

  $date212 = date('d',$date21);
  $t = date('t',$date21);
  $x=(($date212-$date112)+1)/$t;



 //input date1 and date2
 if ((!empty($date1)) && (!empty($date2)) && (empty($storenum)) && 
(empty($store_region))){
    //my$query = "";

  $result = $dbhandle->query($query) or exit("Error code ({$dbhandle->errno}): {$dbhandle->error}");

            $objPHPExcel->createSheet();
            $objPHPExcel->setActiveSheetIndex(6);
            $objPHPExcel->getActiveSheet()->setTitle('Test')->setCellValue('A1', 'Chapter')
                ->setCellValue('B1', 'Topic')
                ->setCellValue('C1', 'Test')
                ->setCellValue('D1', 'Total Questions')
                ->setCellValue('E1', 'Time');
            $o=2;
            foreach($test as $testval)
            {
                $connection = Yii::$app->db;
                $chapname2 = "SELECT name as 'chapter' from chapter  Where id = '".$testval['chapter_id']."' ORDER BY name ASC";
                $command = $connection->createCommand($chapname2);
                $value = $command->queryOne();

                $objPHPExcel->setActiveSheetIndex(6)
                    ->setCellValue('A'.$o, $value['chapter'])
                    ->setCellValue('B'.$o, $testval['name'])
                    ->setCellValue('C'.$o, $testval['test'])
                    ->setCellValue('D'.$o, $testval['total_questions'])
                    ->setCellValue('E'.$o, $testval['test_time']);
                $topicID[] = $testval['id'];

                $o++;
            }
