数据结构为数组中包含对象--树形结构，用Vue组件的写法实现以下的效果：

树形列表，缩进显示层级，第5级数据加底色，数据样式显色，点击展开折叠数据。本文为用Vue实现方式，另有一篇为用knockout.js的实现方法。

html代码

 <div id="table-component-div">
 <table-component v-for="item in data1" v-bind:list="item"></table-component>
 </div>

组件模板代码

<script type="text/x-template" id="table-component-template">
 <div class="tem">
 <div class="tem-p">
 <div v-on:click="toggleClick"><i v-bind:style="{'visibility':list.number!=0?'visible':'hidden'}">{{list.number}}</i><span>{{list.name}}</span></div>
 <!--绑定数据-->
 <div><span>{{list.energyone}}</span></div>
 <div><span>{{list.energytwo}}</span></div>
 <div><span>{{list.energythree}}</span></div>
 <!--绑定class，使数值显示出区分-->
 <div><span v-bind:class="{'isgreen':list.huanRatio<0,'isred':list.huanRatio>100}">{{list.huanRatio}}<em>%</em></span></div>
 <div><span v-bind:class="{'isgreen':list.tongRatio<0,'isred':list.tongRatio>100}">{{list.tongRatio}}<em>%</em></span></div>
 </div>
 <div class="tem-c">
 <!-- 子组件 -->
 <table-component v-for="itemc in list.child" :list="itemc"></table-component>
 </div>
 </div>
</script>

JavaScript代码

/* 数据结构 */
 var ko_vue_data=[
 {
 name: "总能耗",
 number:"0",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: [
 {
 name: "租户电耗",
 number:"1",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: []
 },
 {
 name: "公共用电",
 number:"2",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: [
 {
 name: "暖通空调",
 number:"2.1",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: [
 {
 name: "冷站",
 number:"2.1.1",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: [
 {
 name: "冷水机组",
 number:"2.1.1.1",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: []
 }
 ]
 },
 {
 name: "热力站",
 number: "2.1.2",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: []
 }
 ]
 }
 ]
 }
 ]
 }
 ];
 /* 注册组件 */
 Vue.component('table-component', {
 template:"#table-component-template",//模板
 props:['list'],//传递数据
 computed:{//计算属性
 isFolder: function () {//判断数据有没有子集，此效果中暂没用到，有需要的可以看下具体使用方式
 return this.list.child && this.list.child.length > 0;
 }
 },
 methods:{
 /* 展开折叠操作 */
 toggleClick:function(event){
 event.stopPropagation();//阻止冒泡
 var _this = $(event.currentTarget);//点击的对象
 if (_this.parent().next().is(":visible")) {
 _this.parent().next().slideUp();
 } else {
 _this.parent().next().slideDown();
 }
 }
 }
 });
 /* 创建实例 */
 new Vue({
 el:"#table-component-div",//挂载dom
 data:{
 data1:ko_vue_data//数据
 }
 })

数据显示完毕，接下来是样式效果，缩进显示层级及底色显示。

css代码

.tem-p{
 clear: both;
 border-bottom: 1px solid #dddddd;
 height: 30px;
 line-height: 30px;
 -webkit-box-sizing: border-box;
 -moz-box-sizing: border-box;
 box-sizing: border-box;
 }
 .tem-p>div{
 float: left;
 width:100px;
 box-sizing: border-box;
 -ms-text-overflow: ellipsis;
 text-overflow: ellipsis;
 white-space:nowrap;
 overflow: hidden;
 text-align: center;
 -webkit-box-sizing: border-box;
 -moz-box-sizing: border-box;
 box-sizing: border-box;
 height: 100%;
 border-right: 1px solid #dddddd;
 }
 .tem-p>div:first-of-type{
 width: 298px;
 text-align: left;
 }
 .tem>.tem-c .tem-p>div:first-of-type{
 padding-left: 30px;

 }
 .lastChild{

 .isred{
 color: red;
 }
 .isgreen{
 color: green;
 }
