当一个表格展示的数据相当多的时候，经常会用到固定列，固定行的事情
原理 是 两个或者多个表格组合行程 固定行或者固定列的情况 ，为了保障样式的统一性
当固定行的时候，要限定宽
当固定列的时候，要限定高
运用的插件 fixed-table.js 以及相关css
例子：
html部分：
<div class="table-scrollable" style="border: 0; overflow: hidden; font-size: 11px;"> <p class="t" style="font-size: 18px;font-weight: bolder;color: #666666;margin: 15px 0 25px"> 待分配人员 </p> <div

这里有一个样式注意点
有的浏览器 td 不会按照规定的宽度展示，可以在里面的table-cell 加上宽度类名 防止 样式跑版
table-cell的话 一定要box-sizing:border-box;word-break: break-all;white-space:nowarp;overflow:hidden;text-overflow:ellipsis;
<td class="w-150"><div class="table-cell w-150">邀请单位</div></td>
