Element-ui el-table 使用 SortableJS 实现表格拖拽https://blog.csdn.net/qq_52126119/article/details/133747289

1、在项目目录下安装 sortablejs：
npm install sortablejs --save
2、在要实现表格拖拽的文件中引入 sortablejs：
import Sortable from 'sortablejs'
<template>
<div class="transfer-r">
				<el-table class="staffRightData" border :max-height="400" :data="staffRightData" stripe style="width: 100%" row-key="id">
					<!-- <el-table-column type="selection" width="55" /> -->
					<el-table-column type="index" label="序号" width="80" />
					<el-table-column prop="deviceTypeName" label="设备类型" align="center" />
					<el-table-column prop="faultTypeStr" label="故障类型" align="center" />
					<el-table-column prop="faultCode" label="故障代码" align="center" />
					<el-table-column prop="faultDesc" label="故障描述" align="center" />
				</el-table>
</div>
</template>
 
<script>
import Sortable from "sortablejs";
 
export default {
    data() {
        return {
            staffRightData: [{username:"a",id:1},{username:"b",id:2},{username:"c",id:3},{username:"d",id:4},],
        };
    },
    mounted() {
        this.rowDrop();
    },
    methods: {
		// 实现表格可拖拽
		rowDrop() {
			const el = document.querySelector('.transfer-r tbody');
			console.log(el, 55557);
			// 根据具体需求配置options配置项
			const sortable = new Sortable(el, {
				// number 定义鼠标选中列表单元可以开始拖动的延迟时间；
				delay: 0,
				onEnd: (evt) => {
					// 监听拖动结束事件
					console.log(evt.oldIndex, evt.newIndex); // 当前行的被拖拽前的顺序,当前行的被拖拽后的顺序
					// 我们有了 evt.oldIndex 和 evt.newIndex 这两个参数做索引，我们可以根据绑定在表格上面的 data 这个 Array 找到两个相应的记录。就可以针对数据进行操作啦。
					// 下面将拖拽后的顺序进行修改
					const currRow = this.staffRightData.splice(evt.oldIndex, 1)[0];
					this.staffRightData.splice(evt.newIndex, 0, currRow);
					console.log(this.staffRightData, 7777788); //排序后的整个数组
				}
			});
		},
    },
};
</script>
