在前段开发项目过程中我们经常会用到表格，下面青岛星网跟大家分享：div+css实现表头固定内容滚动表格，下面给出详细实现范例代码供大家学习。
<div class="m-demo">
<table>
<thead>
<tr><th>定宽a</th><th>定宽b</th><th>定宽c</th><th>最后列不定宽d</th></tr>
</thead>
</table>
<div class="scroll">
<table>
<tbody>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
</tbody>
</table>
</div>
</div>
<div class="m-demo">
<table>
<thead>
<tr><th>定宽a</th><th>定宽b</th><th>定宽c</th><th>最后列不定宽d</th></tr>
</thead>
</table>
<div class="scroll">
<table>
<tbody>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
<tr><td>定宽a</td><td>定宽b</td><td>定宽c</td><td>最后列不定宽d</td></tr>
</tbody>
