本文给大家介绍vue 使用 sortable 实现 el-table 拖拽排序功能，具体内容如下所示：

npm 下载：

npm install sortablejs --save

引入：

import Sortable from "sortablejs";

代码：

<template>
 <div class="table">
 <el-table ref="dragTable" :data="tableData" border :row-class-name="tableRowClassName">
 <el-table-column prop="date" label="日期"></el-table-column>
 <el-table-column prop="name" label="姓名"></el-table-column>
 <el-table-column prop="address" label="地址"></el-table-column>
 <el-table-column label="操作">
 <template>
 <el-button class="move" type="text" size="small">拖 拽</el-button>
 </template>
 </el-table-column>
 </el-table>
 </div>
</template>
<script>
import Sortable from "sortablejs";
export default {
 data() {
 return {
 tableData: [
 {
 id: "1",
 name: "text_1",
 date: "1111-11-11",
 address: "测试_1",
 },
 {
 id: "2",
 name: "text_2_不可拖拽",
 date: "2222-22-22",
 address: "测试_2_不可拖拽",
 disabled: true,
 },
 {
 id: "3",
 name: "text_3",
 date: "3333-33-33",
 address: "测试_3",
 },
 {
 id: "4",
 name: "text_4",
 date: "4444-44-44",
 address: "测试_4",
 },
 {
 id: "5",
 name: "text_5",
 date: "5555-55-55",
 address: "测试_5",
 },
 ],
 };
 },
 methods: {
 // 创建sortable实例
 initSortable() {
 // 获取表格row的父节点
 const ele = this.$refs.dragTable.$el.querySelector(
 ".el-table__body > tbody"
 );
 // 创建拖拽实例
 let dragTable = Sortable.create(ele, {
 animation: 150, //动画
 handle: ".move", //指定拖拽目标，点击此目标才可拖拽元素(此例中设置操作按钮拖拽)
 filter: ".disabled", //指定不可拖动的类名（el-table中可通过row-class-name设置行的class）
 dragClass: "dragClass", //设置拖拽样式类名
 ghostClass: "ghostClass", //设置拖拽停靠样式类名
 chosenClass: "chosenClass", //设置选中样式类名
 // 开始拖动事件
 onStart: () => {
 console.log("开始拖动");
 },
 // 结束拖动事件
 onEnd: (e) => {
 console.log(
 "结束拖动",
 `拖动前索引${e.oldIndex}---拖动后索引${e.newIndex}`
 );
 },
 });
 },
 // 设置表格row的class
 tableRowClassName({ row }) {
 if (row.disabled) {
 return "disabled";
 }
 return "";
 },
 },
 mounted() {
 this.initSortable();
 },
};
</script>
<style lang='scss'>
// 拖拽
.dragClass {
 background: rgba($color: #41c21a, $alpha: 0.5) !important;
}
// 停靠
.ghostClass {
 background: rgba($color: #6cacf5, $alpha: 0.5) !important;
}
// 选择
.chosenClass:hover > td {
 background: rgba($color: #f56c6c, $alpha: 0.5) !important;
}
</style>
