improve-gantt-elastic（vue2中甘特图实现与引入）

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

 gantt-elastic官网gantt-elastic | Gantt Chart [ javascript gantt chart, gantt component, vue gantt, vue gantt chart, responsive gantt, project manager , vue projects ]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

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。

dayjs  
gantt-elastic  
gantt-elastic-header  
resize-observe-polyfill  
vue-slider-component  
vue-switches

(2) package.json版本锁定

"dependencies": {"dayjs": "^1.8.14","gantt-elastic": "^1.0.12","gantt-elastic-header": "^0.1.11",
}

(3) demo引入

<template><gantt-elastic:options="options":tasks="tasks"@tasks-changed="tasksUpdate"@options-changed="optionsUpdate"@dynamic-style-changed="styleUpdate"><gantt-header slot="header"></gantt-header></gantt-elastic>
</template><script>

3.gantt-elastic-h

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。

使用文档 | gantt-elastic-h | 使用文档https://jianguoht.github.io/gantt-elastic-h/doc.html#options-tasklist-columns
