为什么不能实现表格行的高度定义?
<!DOCTYPE   html   PUBLIC   "-//W3C//DTD   XHTML   1.0   Transitional//EN "   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html   xmlns= "http://www.w3.org/1999/xhtml ">
<head>
<meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 "   />
<title> 无标题文档 </title>
</head>

<body   style= "height:100% ">
<table   width= "100% "   border= "1 "   style= "height:100% ">
    <tr>
        <td   style= "height:20px "> &nbsp; </td>
    </tr>
    <tr>
        <td   style= "height:20px "> &nbsp; </td>
    </tr>
    <tr>
        <td> &nbsp; </td>
    </tr>
</table>
</body>
</html>

这样三行距离一样,我想让上两行高度固定,不行。这是为什么啊
