グリッドを使ってHTMLテーブルをExcelにエクスポートするには

Question

Excel/PDFにテーブル/データをエクスポートするのは新しいです。しかしこれまでは、HTMLテーブルをExcel（xls）にエクスポートするためのjQueryを作成しました。問題は、Excelのグリッドが表示されないことです。 Excelの出力の例を次に示します。ここで

輸出に私のコードです：ここでは

$(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(); 
    }); 
}); 

は私のHTMLは

<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>USAGE PER 1K</center></th> 
    </tr>

Answer 1

  $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++; 
      } 

です
