LayUI中表格树折叠 --

1、先将插件源码进行下载，新建 tableTree.js 文件，将源码放进去

2、将 tableTree.js 文件 配置之后，在需要使用的页面进行引入：

layui.define(["tableTree"],function (exports) {
    var tableTree = layui.tableTree;

   // 获取树图的数据
	var handleList = function() {
		// 假数据
		let tableData = [{
		    "pid": "0", 
		    "title": "1",
		    "parentTitle": null,
		    "sid": "1111111111",
		    "children": null
		  },
		  {
		    "pid": "1111111111",
		    "title": "1-1",
		    "parentTitle": "1",
		    "sid": "2"
		},
		  {
		    "pid": "1111111111",
		    "title": "1-2",
		    "parentTitle": "1",
		    "sid": "3"
		},
		  {
		    "pid": "0",
		    "title": "2",
		    "parentTitle": null,
		    "sid": "2222222"
		},{
		    "pid": "0",
		    "title": "3",
		    "parentTitle": null,
		    "sid": "3333333"
		},{
		    "pid": "0",
		    "title": "4",
		    "parentTitle": null,
		    "sid": "44444"
		},{
		    "pid": "0",
		    "title": "5",
		    "parentTitle": null,
		    "sid": "5555"
		},{
		    "pid": "5555",
		    "title": "5",
		    "parentTitle": "5",
		    "sid": "6"
		}]
		renderTable(tableData)
	}
	
	// 表格渲染
    var  renderTable = function (tableData) {
		tableTree.render({
			id: 'test',       //做刷新的时候需要用ID
			tree: {
                 iconIndex: 3, // 展开图标显示再第几列
                 isPidData: true, // // pid形式数据转children形式
                 idName: 'sid', // 子id
                 pidName: 'pid', // 父id
                 openName: 'open',// 是否默认展开的字段名
             },
			elem: '#test',	//表格id
			skin: 'line' //表格风格
			, page: false//是否显示分页
			, limit: 100
			,cols: [[ //标题栏
				{ field: 'sid', hide: true },
				{ type: 'radio'}
				, { field: 'title', title: '名称', align: 'left', width: 200 }
				, {
					field: 'opt', title: '操作', templet:
						function (item) {
							if (item.sid < 100000) {
								return '<a class="layui-btn layui-btn-normal layui-btn-xs" lay-event="edit"><i class="layui-icon layui-icon-edit"></i> </a>'
							}
							return '<a class="layui-btn layui-btn-normal layui-btn-xs" lay-event="edit"><i class="layui-icon layui-icon-edit"></i> </a><a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del"><i class="layui-icon layui-icon-delete"></i></a>'
						}
				}
			]],
			data: tableData,
			//数据渲染完的回调
			done: function () {
			}
			, event: true
		})
	};

    // 单选框点击事件
	tableTree.on('checkbox(LAY-model-manager)', function (obj) {
		var data = obj.data;
		console.log('拿到的当前行的数据', data)
	});

	// 表格操作事件
	tableTree.on("tool(LAY-model-manager)", function (obj) {
		var data = obj.data;
		var layEvent = obj.event;
		var tr = obj.tr;
		if ("del" === layEvent) {
			console.log(删除的数据', data)
		} else if ("edit" === layEvent) {
			console.log(操作的数据', data)
		}
	});
		
	var Class = {
		init: function () {
			// 先请求数据
			handleList()
			return this;
		},
	};
  }
);

效果图：
