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>
