有人能告诉我如何为内表创建滚动条吗？内部表不显示在容器中.我把容器黄色的背景着色了.桌子本身是蓝色的.
我想在桌子上看到一个滚动条.

和这里:
<html>
<body>
<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">
<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>
</td>
</tr>
</table>
</div>
<body>
</html>
我需要一个匹配 0 到 99.999 之间数字的正则表达式（99,999 也有效）。
有效示例：
1,1
99.9
12.876
1,777
无效示例：
9837,83
-12,24
11.1112
