我有一张桌子
<form id="form1">
<table style="width:75%;font-size:15px;" align="center" id="info" >
...
</table>
</form>
在缩小浏览器时，我希望相应地适应表格。我试着保持这个位置：亲戚。仍然不起作用。任何线索？
你必须直接给出表的宽度。
<form id="form1">
<table width="500" border="1" align="left" id="info" >
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
</tr>
</table>
</form>您尝试使用的设计称为响应式设计。有很多库用于创建响应式网页设计。以下提到的可能是使您的网页在各种设备上响应的不同方法，例如：桌面，平板电脑，移动设备。

<h2>Basic Table</h2>
<p>The .table class adds basic styling (light padding and only horizontal dividers) to a table:</p>
<table class="table">
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
</tr>

<tbody>
<tr>
<td>John</td>
