推荐答案
用div包裹内部表。通过使它具有自动或滚动溢出的宽度和高度样式，使div可滚动。
wrap your inner table with a div. Make that div scrollable by giving it the width and height styles with overflow as auto or scroll.
<div style="width:1000px;margin-left:auto;margin-right:auto;background-color: yellow; height: 1000px;">
<table style="background-color: blue">
<tr>
<th>column1</th>
<th>column2</th>
<th>column3</th>
<th>column4</th>
</tr>
<tr>
<td>columnvalue1</td>
<td>columnvalue2</td>
<td>columnvalue3</td>
<td>columnvalue4</td>
</tr>
<tr>
<td colspan="4">
<div style="max-height: 100px; max-width: 100px; width: 100px; overflow: auto;">
<table>
<tr>
<th>SubColumn1</th>
<th>SubColumn2</th>
<th>SubColumn3</th>
<th>SubColumn4</th>
<th>SubColumn5</th>
<th>SubColumn6</th>
<th>SubColumn7</th>
<th>SubColumn8</th>
<th>SubColumn9</th>
<th>SubColumn10</th>
<th>SubColumn11</th>
<th>SubColumn12</th>
<th>SubColumn13</th>
<th>SubColumn14</th>
</tr>
<tr>
<td>subvalue1</td>
<td>subvalue2</td>
<td>subvalue3</td>
<td>subvalue4</td>
<td>subvalue5</td>
<td>subvalue6</td>
<td>subvalue7</td>
<td>subvalue8</td>
<td>subvalue9</td>
<td>subvalue10</td>
<td>subvalue11</td>
<td>subvalue12</td>
<td>subvalue13</td>
<td>subvalue14</td>
</tr>
</table>
</div>
</td>
</tr>
</table>
