1.前言
项目开发中需要使用甘特图展示项目实施进度，左侧为表格计划，右侧为图表进度展示。wl-gantt-mater，dhtmlx尝试使用过可拓展性受到限制。gantt-elastic相对简单，可操作性强，基础版本免费。
甘特图（Gantt chart）又称为横道图、条状图（Bar chart），通过条状图来显示项目、进度和其他时间相关的系统进展的内在关系随着时间进展的情况。以提出者亨利·劳伦斯·甘特（Henry Laurence Gantt）先生的名字命名。
2. gantt-elastic（vue2中甘特图实现与引入）
2.1 gantt-elastic
官方demo
https://neuronetio.github.io/gantt-elastic/2.2 npm install引入
不受网络限制直接npm install在项目中
javascript
npm install --save gantt-elastic
npm install --save gantt-elastic-header # 可选，根据需求安装将对应的demo组件引入对应的项目。
2.3内网引入
(1)拉取github上的gantt-elastic项目
将对应需要的依赖进行复制到需要开发的项目依赖中node_module。
需要复制的依赖包，相关依赖包已上传到博客资源中，可自行下载使用。
java
dayjs
gantt-elastic
gantt-elastic-header

基于 gantt-elastic的拓展封装，基本功能相较gantt-elastic完善。在使用gantt-elastic可参考gantt-elastic-h的Api文档。也可选择使用gantt-elastic-h来实现参考使用文档自行完成。
