我可以将<form>作为模态放在表中

Question

我有一个关于表格中的表格的问题如果我把表格放在表格中作为模态有一个红色条并且不等于结束标签形式，我想知道我是否遵循规则或在HTML中编码不好？

  <table>
   <thead>
      <tr>
        <th>Status</th>
        <th>Actions</th>
     </tr>
    </thead>
   <?php 
    $conn = mysqli_connect($servername, $username, $password, $database);
   $id=$_GET["id"];
 $sqls = "SELECT resident_id, complaints_id, nature_of_complaints, status 
 FROM table_complaints WHERE resident_id=?";

    mysqli_stmt_store_result($stmt );
    if (mysqli_stmt_num_rows($stmt ) > 0) {

  while(mysqli_stmt_fetch($stmt )) { ?>
  <tr>
    <td style="text-transform: capitalize"><?php echo 
                   substr($nature_of_complaints,0,8);?>..</td>
    <td style="text-transform: capitalize"><?php 
                    echo $status?></td>
    <td><a href="#" onclick="document.getElementById('id016<?php echo 
           $complaints_id?>').style.display='block'" >Add</a></td>
 </tr>

 <div id="id016<?php echo $complaints_id?>" class="modal">
    <div class="modal-content">
        <header> 
             <p>Involvement</p>
         </header>
 <form action="involvement.php" method="POST">
    <input name="resid" value="<?php echo $resident_id?>" type="hidden">
    <input name="compid" value="<?php echo $complaints_id?>" type="hidden">
    <input type="submit" name="submit" value="Add">
  </form>
   </div>
     <footer>
     <button type="button" onclick="document.getElementById('id016<?php echo 
        $complaints_id?>').style.display='none'">Close</button>
    </footer>
   <?php 
    }
} else {   ?>
<tbody><tr><td><?php echo "No Complaints";?></td></tr></tbody>
   <?php
}

  </table>
