vue 甘特图 vxe-gantt 手动增加一条依赖线，删除连接线的用法

vue 甘特图 vxe-gantt 手动增加一条依赖线，删除连接线的用法,通过设置 links 定义连接线,from 对应源任务的行主键,tom 对应目标任务的行主键

0 FinishToStart 结束后才开始，表示一个任务必须在另一个任务开始之前完成

1 StartToFinish 开始到结束，表示从某个过程的开始到结束的整个过程

2 StartToStart 开始后才开始，表示一个活动结束了，另一个活动才能开始，它们之间按先后顺序进行

3 FinishToFinish 完成到完成，表示一个任务必须在另一个任务完成之后才能完成

过调用 setTaskLinks、clearTaskLinks 方法来设置或清除连接线可以很简单的画连接线或清除连接线
