用css 给tbody加垂直滚动条

思路就是

1，把tbody设置成display:block，然后就对其高度设置一个固定值，overflow设置成auto。

2，把thead的tr设置成display:block。

3，因为都设置成block所以要给td手动添加宽度 width:200px

代码如下：

<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>
