如何在表格中添加水平线？

Question

以下是表格代码:

<table cellpadding="0" cellspacing="" width="100%" border="0">
  <tbody>
    <tr class="pack_list_divider">
      <td width="30%" rowspan="2">
        <img id="coursimg" src="test_listings_files/default_package_image.png" alt="Section wise test" border="0">
      </td>
      <td width="25%">
        <p class="pckgvalidity">
          Validity : 1 Year&nbsp;
        </p>
      </td>
      <td width="35%">
        <p class="pckgvalidity">Number of Tests : 0
        </p>
      </td>
      <td width="20%" valign="middle">
        <!--<p id="test_list_loader" height="20" align="center" style="display:none;"></p> -->
        <a href="http://localhost/abc/pqr/lmn/web/online-test-packages?op=get_package_detail&amp;test_pack_id=21e86b3ebf6a8af2a9fcf136c4f8e88a" class="view_test_package_details">Test Details</a>
      </td>
    </tr>
    <tr>
      <td colspan="2" width="50%" valign="top">
        <p class="descp">
          sectionm wise tests
        </p>
      </td>
      <td width="20%">
        <p class="pckgrs"> <span class="rs fl" style="color:#333333; font:25px bold; margin:0px 0px 10px 10px;"> Free &nbsp; </span>
          <span> 
           <a class="user-not-loggedin more addcart fl" href="http://localhost/entrance_prime/Entrance_Prime/entprm/web/my_cart.php?pack_id=21e86b3ebf6a8af2a9fcf136c4f8e88a&amp;pack_type=test&amp;op=aa" id="21e86b3ebf6a8af2a9fcf136c4f8e88a" value="21e86b3ebf6a8af2a9fcf136c4f8e88a" style="background:url(../images_new/add_account.png) 0 0 no-repeat;">&nbsp;</a>             
           </span>
        </p>
      </td>
    </tr>
  </tbody>
</table>

有关的屏幕截图也附有.在其中我已经指定了我想要水平线的位置.我尝试了很多技巧,但没有一个为我做过魔术.任何人都可以帮我解决这个问题吗？提前致谢.

Answer 1

使用表头并在其中添加下划线

table { border-collapse:collapse; }
table thead th { border-bottom: 1px solid #000; }

<table>
  <thead>
    <tr>
      <th>Valididty></th>
      <th>No Of Tests</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Test</td>
      <td>Test</td>
    </tr>
  </tbody>
</table>    

使用CSS,您可以设置标题行的样式.使每个单元格具有底部边框.

Answer 2

我用这个技巧:

<table>
  <tr style="border-bottom:1px solid black">
    <td colspan="100%"></td>
  </tr>
  <tr> ... </tr>
</table>

    </tr>
    <tr>
