PHP将表拆分成较小的表

Question

有人可以帮助我将PHP表拆分为较小的可折叠表吗？
我目前正在运行此查询，以从数据库中获取结果：

$querytasks = 
  "SELECT *
    FROM tasks
    INNER JOIN usercontract on usercontract.Contract = tasks.contract
    INNER JOIN users on users.ID = usercontract.UserID
    WHERE (users.Username='$Username' AND users.ID = usercontract.UserID)
    ORDER BY status, tasks.contract DESC, itemgroup DESC, item DESC";
$statement2 = $dbh->prepare($querytasks);
$statement2->execute();
$tasks = $statement2->fetchAll();
$statement2->closeCursor();

然后我使用一个foreach循环为该查询的每个结果在表中创建一行：

<table id="mytable" class="fixed_header">
  <thead class="tbl-header" style="background-color: #007BFF;">
    <tr >
      <th>Contract</th>
      <th>Task Group</th>    
      <th>Task Description</th>
      <th>Assigned By</th>
      <th>Assigned To</th>
      <th>Status</th>    
      <th>Due Date</th>
      <th>ID</th>
      <th>Edit</th>
    </tr>
  </thead>

  <tbody class="tbl-content">
    <?php foreach ($tasks as $task) : ?>

    <tr style="display: none;">
      <td><?php echo $task['contract']; ?></td>
      <td><?php echo $task['itemgroup']; ?></td>
      <td><?php echo $task['item']; ?></td>
      <td><?php echo $task['assignedby']; ?></td>
      <td><?php echo $task['assignedto']; ?></td>
      <td><?php echo $task['status']; ?></td>
      <td><?php echo $task['due']; ?></td>
      <td><?php echo $task['id']; ?></td>
      <td><a class="btn btn-info edit"  aria-label="Settings" onclick="updateTask('<?php echo $task['contract']; ?>','<?php echo $task['itemgroup']; ?>','<?php echo $task['item']; ?>','<?php echo $task['assignedby']; ?>','<?php echo $task['assignedto']; ?>','<?php echo $task['status']; ?>','<?php echo $task['due']; ?>','<?php echo $task['id']; ?>')">
      <i class="fa fa-pencil-square-o" aria-hidden="true" ></i>
      </a> </td>
    </tr>
  </tbody> <?php endforeach; ?>
</table>

我的表当前如下所示：

我希望它看起来像这样：

“登机点：Chanda Nagar”将改为“任务组：预警通知”，而“登机点kphb”将是“任务组：一般通信”

我相信可以使用JavaScript或jQuery完成。
