實(shí)現(xiàn)一個(gè)樹形表格的時(shí)候有多種方法：比如把 ztree 的樹形直接拼接成表格皮仁，或者用強(qiáng)大的 jqgrid 實(shí)現(xiàn)狐肢，今天介紹一個(gè)比較輕量級(jí)的實(shí)現(xiàn)：使用bootstrap-table + treegrid 形用。
- 引入 jquery.js藻雪、bootstrap-table.js砰琢、bootstrap-table-treegrid.js胡桨、jquery.treegrid.js 以及相應(yīng)的 css 文件：bootstrap.css扣孟、bootstrap-table.css烫堤、jquery.treegrid.css；
- 后臺(tái)傳到前臺(tái)的 json 必須含有 id凤价、pid字段鸽斟，有 id pid 才能形成樹結(jié)構(gòu)（這里為了演示，把 json 寫成固定的了利诺，實(shí)際中要從后臺(tái)獲雀恍睢）；
- 在使用過(guò)程中可以參考 bootstrap-table 的設(shè)置參數(shù)慢逾，通過(guò)不同的設(shè)置以達(dá)到自己想要的效果立倍；
