html - 表格格式

Question

我有以下表格结构。我尝试添加空的 tds div，以在图像中获得以下格式，但无法正确设置。任何想法将不胜感激。

<table border="0" cellpadding="1" cellspacing="0" width="100%">
    <tR>    
    <td align="center"> <strong>ONE</strong></td> 

    <td align="center"><strong> TWO</strong></td>

    <td align="center"><strong>THREE</strong></td>
    </tR>

    <tr>
        <td align="left">Quiz NAME</td>
        <td align="right">FINAL</td>
        <td align="right">USS </td>
        <td align="right">PA </td>
        <td align="right">INTL </td>        
        <td align="right"> FINAL</td>
        <td align="right"> USS</td>
        <td align="right"> PA </td>
        <td align="right"> INTL </td>
        <td align="right"> FINAL</td>
        <td align="right"> USS</td>
        <td align="right"> PA</td>
        <td align="right">INTL</td>     
    </tr>
    <TR>DATA HERE</TR>

   </table>

Answer 1

这是工作代码:

<table border="0" cellpadding="1" cellspacing="0" width="100%">
<tR>    
<td colspan="4" align="center"> <strong>ONE</strong></td> 

<td colspan="4" align="center"><strong> TWO</strong></td>

<td colspan="4" align="center"><strong>THREE</strong></td>
</tR>

<tr>

    <td align="center"align="center">FINAL</td>
    <td align="center" >USS </td>
    <td align="center"align="center">PA </td>
    <td align="center">INTL </td>        

    <td align="center"> FINAL</td>
    <td align="center"> USS</td>
    <td align="center"align="center"> PA </td>
    <td align="center"> INTL </td>

    <td align="center"> FINAL</td>
    <td align="center"> USS</td>
    <td align="center"> PA</td>
    <td align="center">INTL</td>     
</tr>
