你如何在JSP中用spring創建這樣的表。該行通過循環生成。該行必須包含兩個子標題的多個數據行。對於每一行，在子標題中都有多個表格數據行。例如：數據3.1.1對應循環中的數據3.1.2。

像這樣：

<table> 
    <tr> 
     <td rowspan="2">header 1</td> 
     <td rowspan="2">header 2</td> 
     <td colspan="2">header 3</td> 
    </tr> 
    <tr> 
     <td>subheader</td> 
     <td>subheader</td> 
    </tr> 
    <tr> 
     <td rowspan="3">rowdata 1</td> 
     <td rowspan="3">rowdata 2</td> 
     <td>rowdata 3.1.1</td> 
     <td>rowdata 3.1.2</td> 
    </tr> 
    <tr> 
     <td>rowdata 3.2.1</td> 
     <td>rowdata 3.2.2</td> 
    </tr> 
    <tr> 
     <td>rowdata 3.3.1</td> 
     <td>rowdata 3.3.2</td> 
    </tr> 
</table>
