vue中使用gantt-elastic实现可拖拽甘特图的示例代码

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。

运行成功就是这样的页面了。

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~~
