显示代码后，就会展示出对应的代码，下面是对这部分代码进行分析的图解
Table表格按钮，找到需要的表格效果，并复制代码，将html标签拷贝到<div id="app"></div>中，如下所示
head标签中，如下所示
<el-table>标签上有一个事件@selection-change="handleSelectionChange"，这里绑定的函数也需要从官网拷贝到我们自己的页面代码中，函数代码如下所示：
multipleSelection，所以还需要定义出该模型数据。标号列也用同样的方式进行拷贝并修改
在Element官网找到Pagination分页，在页面主体部分找到需要的效果，如下所示
点击显示代码，找到完整功能对应的代码，接下来对该代码进行分析
上述代码属性说明
page-size：每页显示的条目数page-sizes：每页显示个数选择器的选项设置:page-sizes="[100, 200, 300, 400]"对应的页面效果如下：
currentPage：当前页码。我们点击哪个页面，此属性值就是几total：总记录数。用来设置总的数据目录条数，该属性设置后，Element会自动计算出需要分多少也给我们展示对应的代码事件说明
size-change：pageSize改变的时候会触发。也就是当我们改变了每页显示的条目数后，该事件会触发
current-change：currentPage改变的时候会触发。也就是当我们点击了其他的页码后，该事件会复发
