实现一个树形表格的时候有多种方法：比如把 ztree 的树形直接拼接成表格，或者用强大的 jqgrid 实现，今天介绍一个比较轻量级的实现：使用bootstrap-table + treegrid 。
- 引入 jquery.js、bootstrap-table.js、bootstrap-table-treegrid.js、jquery.treegrid.js 以及相应的 css 文件：bootstrap.css、bootstrap-table.css、jquery.treegrid.css；
- 后台传到前台的 json 必须含有 id、pid字段，有 id pid 才能形成树结构（这里为了演示，把 json 写成固定的了，实际中要从后台获取）；
- 在使用过程中可以参考 bootstrap-table 的设置参数，通过不同的设置以达到自己想要的效果；
