テーブルの特定の列の幅を広げたい

Question

ここに学生ID、学生名、質問1などのような列があります。width of column "question"を増やしたいと思います。これどうやってするの？

テーブルヘッダtag like width="100"にオブジェクトを追加することで幅を追加しようとしましたが、単純なhtmlコードとして機能しますが、ここで必要なコードでは機能しません。 '

<?php 
        if (isset($result_display)) { 
         echo "<p><u>Result</u></p>"; 
         if ($result_display == 'No record found !') { 
          echo $result_display; 
         } else { 
          echo "<table class='result_table'>"; 
          echo '<tr><th>Student ID</th><th>Student Name</th><th>Question#1</th><th>Answer#1</th><th>Question#2</th><th>Answer#2</th><th>Question#3</th><th>Answer#3</th><th>Question#4</th><th>Answer#4</th><th>Question#5</th><th>Answer#5</th><th>Question#6</th><th>Answer#6</th><th>Question#7</th><th>Answer#7</th><th>Question#8</th><th>Answer#8</th><th>Question#9</th><th>Answer#9</th><th>Question#10</th><th>Answer#10</th><th>Question#11</th><th>Answer#11</th><th>Question#12</th><th>Answer#12</th><th>Question#13</th><th>Answer#13</th><th>Question#14</th><th>Answer#14</th><th>Question#15</th><th>Answer#15</th><tr/>'; 
          foreach ($result_display as $value) { 
           echo '<tr>' . '<td class="e_id">' . $value->id . '</td>' .'<td class="name">' . $value->Student_name . '</td>' . '<td>' . $value->question1 . '</td>' . '<td class="j_date">' . $value->Answer1 . '</td>' . '<td>' . $value->question2 . '</td>' . '<td class="mob">' . $value->Answer2 . '</td>' . '<td >' . $value->question3 . '</td>' .

'<tr/>'; 
          } 
          echo '</table>'; 
         } 
        } 
        ?> 

       </div> 
      </div> 

Answer 1

thタグにスタイル属性を使用します。

​​

これはジョブを実行する必要があります。そうでない場合は、％を使用することもできます。

<th style="width: 30%;">Question#1</th>
