怎样写CSS可以让一个表格的内外框线条都是1像素？

[ynduanlian]

style=" border-style:solid; border-width:1px; border-color:Blue; "
只能设写外边框，内分隔线要怎么写？

<style type="text/css">
	.tb{border:1px solid blue;border-collapse:collapse;}
	.tb tr td{border:1px solid blue;padding:0;margin:0}
</style>
<table class="tb" cellpadding = "0">
	<tr>
		<td>TEST</td>
		<td>TEST</td>
	</tr>
	<tr>
		<td>TEST</td>
		<td>TEST</td>
	</tr>
	<tr>
		<td>TEST</td>
		<td>TEST</td>
	</tr>
</table>
