这个注册表单最下面怎么空那么多啊？

想让忘记密码那里津贴表格下边框，可就是弄不上去，，，，代码如下

<table width="200"  border="0" align="center" cellpadding="0" cellspacing="1" class="td2" >
  <tr>
    <td><form name="form1" id="form1" method="post" action="usermodify.asp">
      <table width="200"  border="0" align="center" cellpadding="0" cellspacing="1">
        <tr>
          <td colspan="2"><div align="center" style="font-weight: bold; font-size: 12px; color: #FF0000;">新用户登录</div></td>
          </tr>
        <tr>
          <td width="44%"><div align="center"><span style="font-weight: bold; color: #666666;">用户名</span></div></td>
          <td width="56%"><input name="user" type="text" class="line"style="height:20px; width:150px;font-size :15px;border: 1px solid #666666;" size="30" maxlength="30" /></td>
        </tr>
        <tr>
          <td><div align="center"><span class="style1">密码</span></div></td>
          <td><input class="line" style="height:20px; width:150px;font-size :15px;border: 1px solid #666666; "name="pass" type="password" size="30" /></td>
        </tr>
      
        <tr>
          <td height="20" colspan="2"><div align="right">
            <table width="100%"  border="0" align="center" cellpadding="0" cellspacing="1">
              <tr>
                <td><div align="right"><a href="#" onclick="queryAction()"><img src="images/tijiao2.jpg" width="79" height="27" border="0"></a></div></td>
                <td><div align="left"><a href="productreg.asp"><img src="images/zc1.jpg" width="79" height="27" border="0"></a></div></td>
              </tr>
            </table>
          </td>
          </tr>
          
           <tr>
          <td> </td>
          <td><div align="center"><a href="zhaohui.asp"><img src="images/wangji.jpg" border="0"  /></a></div></td>
        </tr>
