实现GridView的多重表头

以前做过的东西都是很规则的表,所以可能很少注意多重表头的表,看到一个例子,发出来看看,相信大家都一看就懂,不过我有时候脑子慢,好比说我一直知道有colspan,自己没想到还有个rowspan.
代码是:

<table border=1 bordercolor="#ccccff" cellpadding=0 cellspacing=0>
         <tr>
            <th rowspan="4">产品</th>
            <th colspan="2">主板</th>
            <th colspan="2">CPU</th>
        </tr>
        <tr>
            <th>华硕</th>
            <th>技嘉</th>
            <th>INTEL</th>
            <th>AMD</th>
        </tr>
        <tr>
            <th>NT 4,000</th>
            <th>NT 3,500</th>
            <th>NT 8,000</th>
            <th>NT 6,000</th>
        </tr>
             <tr>
            <th colspan="2">注一：国产</th>
            <th colspan="2">注二：进口</th>
        </tr>
    </table>

效果图是:
