ASP/html如何让某个单元格边框不显示？
<style=border:none>
<td colspan="4"> </td>
</tr>
比如这行我应该怎么写，才能让这个单元格的边框不显示
<tr style=“border:none”>
<td colspan="4"> </td>
</tr>
这样也不行 展开
<head>
<style>
.tdp
{
border-bottom: 1 solid #000000;
border-left: 1 solid #000000;
border-right: 1 solid #000000;
border-top: 1 solid #000000;
}
</style>
</head>
<table border="0" width="400" cellspacing="0" cellpadding="4">
<tr>
<td class="tdp" align="center">这</td>
