Codice PHP:

<html>
<head>

</head>
<body>
<table>
<tr><td>riga1</td></tr>
<tr><td>riga2</td></tr>
</table>


<script type="text/javascript">
var trs = document.getElementsByTagName("tr");
for(x in trs)trs[x].onclick=function(){location.href='http://www.html.it'};
</script>
</body>
</html> 
se al posto di utilizzare javascript classico puoi usare jquery

Codice PHP:
$(document).ready(
     function(){
         $("tr").click(
              function(){
                   location.href='http://www.html.it'
              }
         )
     }
)
