前言：该组件接收参数为tableData,collumData,max,lineHeight,refe用法说明在组件中已注释，滚动部分采用的transform,滚动速度在内部根据滚动的数据量进行了设置，使用的朋友如果有改进的地方请留言，共同做好这个组件
上代码

1 公共css中
@keyframes scroll
{
0% {transform: translateY(0%)}
100% {transform: translateY(-100%)}
}

@-webkit-keyframes scroll
{
0% {transform: translateY(0%)}
100% {transform: translateY(-100%)}
}
@-moz-keyframes scroll
{
0% {transform: translateY(0%)}
100% {transform: translateY(-100%)}
}
