使用相對寬度調(diào)整表格問題

    代碼如下:
    <tr> <th width="12%">AAAAA</th> <th width="12%">BBBBB</th> <th width="12%">CCCC</th> <th width="12%">DDDDD</th> <th width="12%">EEEEEE&
    <tr>
    <th width="12%">AAAAA</th>
    <th width="12%">BBBBB</th>
    <th width="12%">CCCC</th>
    <th width="12%">DDDDD</th>
    <th width="12%">EEEEEE</th>
    <th width="12%">FFFFF<br/>FF</th>
    <th width="12%">GGGGG</th>
    <th width="16%">HHHHH</th>
    </tr>
    使用%比調(diào)整表格時候，總和不能超過100，否則%比不起作用．
