vue3 甘特图

vue3中，项目甘特图实现项目进度条——封装组件之tabs标签页的使用、定义方法实现动态样式style、reduce方法、数组每个下标对应的当前下标前几位之和、new Date（）转换日期格式

效果图

1.1、预警阈值

在这里插入图片描述

1.2、

在这里插入图片描述

2、项目进度甘特图

在这里插入图片描述

需求：

1、展示项目各个节点的执行进度情况

2、只有项目节点实施开始日期，没有百分比或节点实施结束日期，则只标识出起点位置即可

3、根据项目进度或完成情况的百分比或结束日期，展示不同的颜色进行预警

4、结束日期或百分比的打点位置超出项目计划结束日期进行截取至项目计划日期打点位置
