Codeigniter 数据表 如何 link 我的文件专栏

Question

image link

大家好，我想问问是否有人知道如何将特定专栏设为 link，以便用户可以下载该 pdf 文件。

这是我的数据表

   <table id="example" class="table table-striped table-bordered table-hover" style="width:100%">
                                    <thead>
                                        <tr>
                                            <th class="text-center align-middle">Control Number</th>
                                            <th class="text-center align-middle">Attached Form</th>

只需创建一个锚点link

 <?php
  if (!empty($log->file )) {
   echo '<a href="'.$log->file.'" target="_blank" >'.$log->file.'</a>';

  }
