改变头部原理：删除原来表格, 重新建立DOM元素, 重新加载table,实现表头改变
明白了原理, 我相信大家都能写出来了, table.reload(ID, options)目前好像还不支持cons的基础函数变动,只能使用其他方式了,简单暴力,哈哈哈哈哈哈哈哈嗝！！
下面是示例：
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Title</title> <link href="https://www.jb51.net/static/layui/css/layui.css" > </head> <body> <div> <table lay-filter="test"></table> </div> <button>点击改变表头</button> <script type="text/javascript" src="https://www.jb51.net/static/layui/layui.js" charset="utf-8"></script> <script> layui.use(['element', 'jquery', 'table'], function () { var $ = layui.jquery , table = layui.table , element = layui.element; //Tab的切换功能，切换事件监听等，需要依赖element模块 var data = [ { "id": 10000, "username": "user-0", "sex": "女", "city": "城市-0", "sign": "签名-0", "experience": 255, "logins": 24, "wealth": 82830700, "classify": "作家", "score": 57 }, { "id": 10001, "username": "user-1", "sex": "男", "city": "城市-1", "sign": "签名-1", "experience": 884, "logins": 58, "wealth": 64928690, "classify": "词人", "score": 27 }, { "id": 10002, "username": "user-2", "sex": "女", "city": "城市-2", "sign": "签名-2", "experience": 650, "logins": 77, "wealth": 6298078, "classify": "酱油", "score": 31 }, { "id": 10003, "username": "user-3", "sex": "女", "city": "城市-3", "sign": "签名-3", "experience": 362, "logins": 157, "wealth": 37117017, "classify": "诗人", "score": 68 }, { "id": 10004, "username": "user-4", "sex": "男", "city": "城市-4", "sign": "签名-4", "experience": 807, "logins": 51, "wealth": 76263262, "classify": "作家", "score": 6 }, { "id": 10005, "username": "user-5", "sex": "女", "city": "城市-5", "sign": "签名-5", "experience": 173, "logins": 68, "wealth": 60344147, "classify": "作家", "score": 87 }, { "id": 10006, "username": "user-6", "sex": "女", "city": "城市-6", "sign": "签名-6", "experience": 982, "logins": 37, "wealth": 57768166, "classify": "作家", "score": 34 }, { "id": 10007, "username": "user-7", "sex": "男", "city": "城市-7", "sign": "签名-7", "experience": 727, "logins": 150, "wealth": 82030578, "classify": "作家", "score": 28 }, { "id": 10008, "username": "user-8", "sex": "男", "city": "城市-8", "sign": "签名-8", "experience": 951, "logins": 133, "wealth": 16503371, "classify": "词人", "score": 14 }, { "id": 10009, "username": "user-9", "sex": "女", "city": "城市-9", "sign": "签名-9", "experience": 484, "logins": 25, "wealth": 86801934, "classify": "词人", "score": 75 }] var title = [ //表头 {field: 'id', title: 'ID', width: 80, sort: true, fixed: 'left'} , {field: 'username', title: '用户名', width: 80} , {field: 'sex', title: '性别', width: 80, sort: true} , {field: 'city', title: '城市', width: 80} , {field: 'sign', title: '签名', width: 177} , {field: 'experience', title: '积分', width: 80, sort: true} , {field: 'score', title: '评分', width: 80, sort: true} , {field: 'classify', title: '职业', width: 80} , {field: 'wealth', title: '财富', sort: true} ] var title2 = [ //表头 {field: 'id', title: 'ID', width: 80, sort: true, fixed: 'left'} , {field: 'username', title: '用户名', width: 80} , {field: 'wealth', title: '财富', sort: true} ] //第一个实例 var tableIns = table.render({ elem: '#demo' , id: 'demoTest' , height: 312 // ,url: '/demo/table/user/' //数据接口 , data: data , page: true //开启分页 , cols: [title] }); $("#buttonChangeTitle").on("click", function () { $("#myTable").empty(); $("#myTable").append('<table></table>'); //第一个实例 var tableIns2 = table.render({ elem: '#demo' , id: 'demoTest' , height: 312 // ,url: '/demo/table/user/' //数据接口 , data: data , page: true //开启分页 , cols: [title2] }); }) }) </script> </body> </html>
