100tabletrlength

<tr  style="background:#000000;height:1px;width:100%">		<td height="1px;"></td></tr>

这样的话，线总是有一点不到边上，怎么样才能让线100%占据表格？

 <table style="background: #0CA3DC" border="0">		<tr>		<td height="20px;">aaaaaaaa</td>		</tr>		<tr  style="background:#000000;height:1px;width:100%">		<td height="1px;"></td>		</tr>		<tr>		<td>bbbbb</td>		</tr>		<tr> </tr></table>

table加border-collapse:collapse

border-collapse: collapse;

你这样和作边框有什么差？为什么不直接用边框？
