vue+element UI实现树形表格带复选框的示例代码

一：在component文件夹下新建如下treeTable文件夹，里面有2个文件：

eval.js:将数据转换成树形数据

/**

 */
"use strict";
import Vue from "vue";
export default function treeToArray(
 data,
 expandAll,
 parent = null,
 level = null
) {
 let tmp = [];
 Array.from(data).forEach(function(record) {
 if (record._expanded === undefined) {
  Vue.set(record, "_expanded", expandAll);
 }
 let _level = 1;
 if (level !== undefined && level !== null) {
  _level = level + 1;
 }
 Vue.set(record, "_level", _level);
 // 如果有父元素
 if (parent) {
  Vue.set(record, "parent", parent);
 }
 tmp.push(record);
 if (record.child && record.child.length > 0) {
  const child = treeToArray(record.child, expandAll, record, _level);
  tmp = tmp.concat(child);
 }
 });
 return tmp;
}

index.vue:树形表格组件

二：在需要的地方引入该组件：

例如：在component文件夹下新建a.vue:

import treeTable from "./TreeTable";
components: { treeTable },
data() {
 return {
  columns: [
  {
   text: "事件",
   value: "event",
   width: 200
  },
  {
   text: "ID",
   value: "id"
  }
  ],
  data: [
  {
   id: 0,
   event: "事件1",
   timeLine: 50,
   comment: "无"
  },
  {
   id: 1,
   event: "事件1",
   timeLine: 100,
   comment: "无",
   children: [
   {
    id: 2,
    event: "事件2",
    timeLine: 10,
    comment: "无"
   },
   {
    id: 3,
    event: "事件3",
    timeLine: 90,
    comment: "无",
    children: [
    {
     id: 4,
     event: "事件4",
     timeLine: 5,
     comment: "无"
    },
    {
     id: 5,
     event: "事件5",
     timeLine: 10,
     comment: "无"
    },
    {
     id: 6,
     event: "事件6",
     timeLine: 75,
     comment: "无",
     children: [
     {
      id: 7,
      event: "事件7",
      timeLine: 50,
      comment: "无",
      children: [
      {
       id: 71,
       event: "事件71",
       timeLine: 25,
       comment: "xx"
      },
      {
       id: 72,
       event: "事件72",
       timeLine: 5,
       comment: "xx"
      },
      {
       id: 73,
       event: "事件73",
       timeLine: 20,
       comment: "xx"
      }
      ]
     },
     {
      id: 8,
      event: "事件8",
      timeLine: 25,
      comment: "无"
     }
     ]
    }
    ]
   }
   ]
  }
  ]
 };
 },
