td中嵌套table，让table完全填充父元素td

<table  width="100% "  cellspacing=0 cellpadding=0 border=1 >
	<tr>			
		<td style=" 100%;padding: 0"  border=1  >
			<table  width="100% " cellspacing=0 cellpadding=0 border=1 >
				<tr>
					<td>2</td>
					<td>1</td>
					<td>0</td>
					<td>3</td>
				</tr>
		　　</table>
		</td>
	</tr>
	<tr><td>111</td></tr>
</table>
