?给table设置细边框:

.table_border{
	border: solid 1px #B4B4B4;
	border-collapse: collapse;     --折叠样式.
}
.table_border tr th{
	background:url("../../images/gray/bg_table_th.gif") repeat;
	padding-left:4px;
	height:27px;
	border: solid 1px #B4B4B4;
}
.table_border tr td{
	height:25px;
	padding:4px;
	border: solid 1px #B4B4B4;
}

HTML:

<table class="table_border" width="100%" border="0" id="high_light" lang="tabRowData"
         cellpadding="0" cellspacing="0">

         <tr>
               <td><td>
         </tr>
</tabl>

还可以使用行内样式，使表格边框变细;

style="width: 100%; border-collapse: collapse;" cellspacing="0"
