vue 甘特图 vxe-gantt 设置每个进度条分为计划和实际两条，实现上下分布任务条

vue 甘特图 vxe-gantt 设置每个进度条分为计划和实际两条，实现上下分布任务条，实现方式是利用子任务的子视图渲染模式，来间每条任务拆分成2条子任务，就可以利用自带的子视图渲染功能来渲染。

gantt.vxeui.com

由于放2行超出默认高度，所以还需要通过 cell-config.height设置一下行高，再通过树形表格的子任务来渲染

<template>
  <div>
    <vxe-gantt v-bind="ganttOptions"></vxe-gantt>
  </div>
</template>

<script setup>
