vue中使用gantt-elastic实现可拖拽甘特图的示例代码
更新时间：2022年07月07日 10:33:30 作者：suoh's Blog
这篇文章主要介绍了vue中使用gantt-elastic实现可拖拽甘特图,本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
官方例子效果图：
可以横向以及纵向鼠标拖拽表格滑动。可以手动调整列宽等功能
1、安装gantt-elastic
npm install --save gantt-elastic
2、安装gantt-elastic-header
npm install --save gantt-elastic-header
3、当然你项目里面没有安装dayjs的话还需要安装一下，因为他官网的例子用到了
npm install dayjs --save
4、到这里如果你项目里面安了less-loader可能会报错
说你的less-loader版本太高，必须是2.3.1或者3.0.0版本 ，因为我的是5.0版本的
此时需要再次安装指定版本的less-loader
npm install less-loader@3.0.0 --save
然后再次安装dayjs。就ok了
5、官方例子全代码。复制粘贴即可。
<template>
<q-page class="q-pa-sm">

当然他不一定符合你的需求比如表头设置，因此需要通过设置参数数据去实现不同的效果。
缺点：没有开发文档，英文的都没有，很多参数设置需要自己研究。如果改动不大的话还可以参考，跟需求差的多的话不建议使用~~
