  您可以为该任务使用PHP三元运算符和css显示属性

  $ShowHide = ($gid == 'NO') ? 'block' : 'none';
  <td style="display:<?php echo $ShowHide; ?>;"><?php echo round($row9['gstp']/2) ?></td>
  

  我认为这是一个简单的方法来完成任务 . $ShowHide 将根据 $gid 值将显示属性设置为 td .

  在顶部设置标志变量值：

  $gid = $_SESSION['gid'];
  
      if(gid == NO) 
      {
           $flag = true;
  
      }
      else{
              $flag = false;
      }
  
  
      <table class="table">
          <thead>
          <tr>
          <th class="border-0 text-uppercase small font-weight-bold">Sl no</th>
          <th class="border-0 text-uppercase small font-weight-bold">Spares Particulars</th>
          <th class="border-0 text-uppercase small font-weight-bold">Amount</th>
          <th class="border-0 text-uppercase small font-weight-bold">Quantity</th>
          <th class="border-0 text-uppercase small font-weight-bold">GST %</th>
          <th class="border-0 text-uppercase small font-weight-bold">GST AMT</th>
          <th class="border-0 text-uppercase small font-weight-bold">CGST %</th>
          <th class="border-0 text-uppercase small font-weight-bold">CGST AMT</th>
  <?php if($flag) { ?>
          <th class="border-0 text-uppercase small font-weight-bold">SGST %</th>
          <th class="border-0 text-uppercase small font-weight-bold">SGST AMT</th>
  <?php } ?>
          <th class="border-0 text-uppercase small font-weight-bold">Total AMT</th>
           </tr>
              </thead>
              <tbody>
          <tr>
      <td><?php echo $i ?></td>
      <td><?php echo $sparen ?></td>
      <td><?php echo $row9['amt'] ?></td>
      <td><?php echo $row9['quant'] ?></td>
      <td><?php echo $row9['gstp'] ?></td>
      <td><?php echo round($row9['amt']*($row9['gstp']/100)) ?></td>
      <td><?php echo round($row9['gstp']/2) ?></td>
      <td><?php echo round(($row9['amt']*($row9['gstp']/100))/2) ?></td>
  
  <?php if($flag) { ?>    
      <td><?php echo round($row9['gstp']/2) ?></td>
      <td><?php echo round(($row9['amt']*($row9['gstp']/100))/2) ?></td>
  <?php } ?>
  
      <td><?php echo round((($row9['amt']*($row9['gstp']/100))+$row9['amt'])*$row9['quant']) ?></td>
  
      </tr>                            
      </tbody>
      </table>
  

  并检查HTML部分以显示/隐藏TD Headers 及其各自的值 .
