如何使用spring在JSP中创建这样的表。该行是通过循环生成的。该行必须包含两个子标题的多个数据行。对于每一行，子标题中都有多个表数据行。示例：数据3.1.1对应于循环中的数据3.1.2。

像这样：

<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>
