关于vue-tree-chart简单的使用

作者：左手牵♪♡右手

这篇文章主要介绍了关于vue-tree-chart简单的使用方式，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教

vue-tree-chart的使用

项目中需要动态展示组织结构，这里只是展示简单的实现，如果需要更复杂的就需要去深入去实现。

插件安装

npm i vue-tree-chart --save

组件内容：vart.vue

<template>
    <table v-if="treeData.name">
      <tr>
        <td :colspan="Array.isArray(treeData.children) ? treeData.children.length * 2 : 1" 
          :class="{parentLevel: Array.isArray(treeData.children) && treeData.children.length, 
          extend: Array.isArray(treeData.children) && treeData.children.length && treeData.extend}">
          <div :class="{node: true, hasMate: treeData.mate}">
            <div class="person"  :class="Array.isArray(treeData.class) ? treeData.class : []"
