vue版---部分功能收费

1. 安装gantt  或  引入文件

   npm install dhtmlx-gantt -save或import gantt from "/public/static/dhtmlxgantt/dhtmlxgantt.js";
   import "/public/static/dhtmlxgantt/locale/locale_cn.js";

2. 引入---组件

<template>
#节点高度要给，gantt不根据内容撑开<div ref="gantt" class="gantt-container" style="min-height: calc(85vh - 100px); width: 100%; overflow: hidden"></div>
</template>
<script>import gantt from "/public/static/dhtmlxgantt/dhtmlxgantt";import "/public/static/dhtmlxgantt/locale/locale_cn.js";
</script>
