vue 3 使用vuedraggable实现从左往右拖拽

使用vue版本：vue@3.2.37

使用vuedraggable版本：vuedraggable@4.1.0

引用了如下脚本：

<script src="~/lib/vue/vue.global.min.js"></script>
<link href="~/lib/element-plus/index.css" rel="stylesheet" />
<script src="~/lib/element-plus/index.full.js"></script>
<script src="~/lib/element-plus/locale/en.js"></script>
<script src="~/lib/element-plus/locale/zh-cn.js"></script>
<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/lib/sortablejs/Sortable.min.js"></script>
<script src="~/lib/vuedraggable/dist/vuedraggable.umd.min.js"></script>

实现效果如下图：

实现代码如下：

<style>
    .itxst {
        margin: 10px;
        text-align: left;
    }

    .col {
        width: 40%;
        flex: 1;
        padding: 10px;
        border: solid 1px #eee;
        border-radius: 5px;
        float: left;
    }

        .col + .col {
            margin-left: 10px;
        }

    .item {
        padding: 6px 12px;
        margin: 0px 10px 0px 10px;
        border: solid 1px #eee;
        background-color: #f1f1f1;
        text-align: left;
    }

        .item + .item {
            border-top: none;
            margin-top: 6px;
        }

        .item:hover {
            background-color: #fdfdfd;
            cursor: move;
        }

    .item2 {
        padding: 6px 12px;
        margin: 0px 10px 0px 10px;
        border: solid 1px #eee;
        background-color: pink;
        text-align: left;
    }

        .item2 + .item2 {
            border-top: none;
            margin-top: 6px;
        }

        .item2:hover {
            outline: solid 1px #ddd;
            cursor: move;
        }
