【vue2多列拖拽组件】vue.draggable嵌套拖拽使用

背景：因为项目的需求，需要多组拖拽分配，还能支持排序

最近太忙了，没时间描述，直接上完整代码，中文文档看这里​​​​​​​

先介绍一波参数参数

var sortable = new Sortable(el, {
    //一个网页存在多个分组时设置
    //or { name: "...", pull: [true, false, 'clone', array], put: [true, false, array] }
    group: "name",
    //是否允许列内部排序，如果为false当有多个排序组时,多个组之间可以拖拽，本身不能拖拽
    sort: true,
    // 按下鼠标后多久可以拖拽 1000表示1秒
    delay: 0,
    //如果为false按下鼠标不动才计算延时，移动则无效
    delayOnTouchOnly: false,
    //当按下鼠标移动了n个像素时会取消延迟delay事件，即可超过了这个范围无法拖动元素了
    //px, how many pixels the point should move before cancelling a delayed drag event
    touchStartThreshold: 0,
    //启用禁用拖拽
    disabled: false,
    //Store
    store: null,
    //动画效果
    animation: 150,
    // Easing 动画 默认null. See https://easings.net/ for examples.
    easing: "cubic-bezier(1, 0, 0, 1)",
