vue+element UI实现树形表格

本文实例为大家分享了vue+element UI实现树形表格的具体代码，供大家参考，具体内容如下

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.children && record.children.length > 0) {
   const children = treeToArray(record.children, expandAll, record, _level)
   tmp = tmp.concat(children)
  }
 })
 return tmp
}

index.vue:树形表格组件

 


@keyframes treeTableShow {
 from {
  opacity: 0;
 }
 to {
  opacity: 1;
 }
}
@-webkit-keyframes treeTableShow {
 from {
  opacity: 0;
 }
 to {
  opacity: 1;
 }
}

 

.ms-tree-space {
 position: relative;
 top: 1px;
 display: inline-block;
 font-style: normal;
 font-weight: 400;
 line-height: 1;
 width: 18px;
 height: 14px;
}
.ms-tree-space::before {
 content: "";
}
.processContainer {
 width: 100%;
 height: 100%;
}
table td {
 line-height: 26px;
}
.tree-ctrl {
 position: relative;
 cursor: pointer;
 color: #2196f3;
 margin-left: -18px;
}

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"
    },
    {
     text: "时间线",
     value: "timeLine"
    },
    {
     text: "备注",
     value: "comment"
    }
   ],
   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"
   }
  ]
 }
]
      }
     ]
    }
   ]
  };
 },
