目標(biāo)：實(shí)現(xiàn)一個(gè)復(fù)雜table具有以下功能：表格行展開、全部展開、收起、全部收起；可動(dòng)態(tài)配置展示哪些列、調(diào)整列展示順序；動(dòng)態(tài)調(diào)整行順序、行上移、行下移、行移動(dòng)最頂部、行移動(dòng)最底部
一、頁(yè)面效果：
1.全部展開
2.全部收起
?3.配置顯示列
?4.調(diào)整字段順序（拖拽方式）
?5.行操作（查看、修改、刪除、行上下移動(dòng)）
文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-507583.html
二、代碼實(shí)現(xiàn)（vue+Element-ui）
思路：本質(zhì)上就是將表格看成一個(gè)數(shù)組，對(duì)表格的操作當(dāng)成對(duì)數(shù)組的操作。文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-507583.html
