如何显示和隐藏信息

[eversince]

<table name="t1" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>
<input type="checkbox" name="radiobutton" value="radiobutton" onclick="t2.style.display=checked?'':'none';t3.style.display=checked?'':'none';t4.style.display=checked?'':'none'" checked>
显示/隐藏
</td>
</tr>
</table>
<table id="t2" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td> 2
<label>
<input type="text" name="textfield">
</label></td>
</tr>
</table>
<table name="t3" id="t3" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td> 3
<label>
<input type="text" name="textfield2">
</label></td>
</tr>
</table>
<table name="t4" id="t4" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td> 4
<input type="text" name="textfield3"></td>
</tr>
</table>
怎么能让那些隐藏的信息上来就是隐藏的，点复选框后在显示，小弟先谢谢了！

稍微修改一下就可以了：
<table name="t1" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>
<input type="checkbox" name="radiobutton" value="radiobutton" onclick="t2.style.display=checked?'':'none';t3.style.display=checked?'':'none';t4.style.display=checked?'':'none'"> 显示/隐藏
</td>
</tr>
</table>
<table id="t2" width="100%" border="0" cellspacing="0" cellpadding="0" style="display:none;">
<tr>
<td> 2
<label>
<input type="text" name="textfield">
</label></td>
</tr>
</table>
<table name="t3" id="t3" width="100%" border="0" cellspacing="0" cellpadding="0" style="display:none;">
<tr>
<td> 3
<label>
<input type="text" name="textfield2">
</label></td>
</tr>
</table>
<table name="t4" id="t4" width="100%" border="0" cellspacing="0" cellpadding="0" style="display:none;">
<tr>
<td> 4
<input type="text" name="textfield3"></td>
</tr>
</table>
