思路就是

1，把tbody設置成display:block，然后就對其高度設置一個固定值，overflow設置成auto。

2，把thead的tr設置成display:block。

3，因為都設置成block所以要給td手動添加寬度 width:200px

代碼如下：

<table class=”table”>
<thead>
<tr>
<th>Id</th>
<th>Name</th>
<th>Category</th>
<th>MonthAmount</th>
<th>hasBackUp</th>
<th>score</th>
</tr>
</thead>
<tbody>
<tr>
<td>23</td>
<td>South Bearing</td>
<td>Glass/Material</td>
<td>1234444</td>
<td>TRUE</td>
<td>3456.00</td>
</tr>
<tr>
<td>23</td>
<td>South Bearing</td>
<td>Glass/Material</td>
<td>1234444</td>
<td>TRUE</td>
<td>3456.00</td>
