vue仿甘特图开发工程施工进度表

前言

	本文是根据项目实际开发中一个需求开发的demo，仅用了elementUI，可当作独立组件使用，C V即用。
当然没考虑其他的扩展性和一些数据的校验，主要是提供一个处理思路，有需要的小伙伴可以直接复制；本demo的思路是根据开始时间和结束时间动态生成工程时间表，再根据工程的计划开始和结束日期、
实际开始和结束日期再对应单元格生成进度条，最后根据完成进度百分比计算红色进度条。

一、demo成品图

在这里插入图片描述
表格使用的是elementUI，表头是动态的，根据开始日期的年月和结束时间的年月计算获取；
单元格第一行绿色进度条是计划工程进度，第二行绿色是实际功能进度条，红色是实际进度的百分比

二、代码
