el-tabel实现拖拽排序

1、使用npm安装sortableJs插件

npm install sortablejs --save

2、在需要使用的页面进行引入

import Sortable from 'sortablejs'

3、表格拖拽排序完整代码

<template><div class="home"><el-table :data="tableData" style="width: 100%"><el-table-column v-for="(item, index) in col" :key="`col_${index}`" :prop="item.prop" :label="item.label"></el-table-column></el-table></div>
</template><script setup>
import Sortable from 'sortablejs'; //引入插件
import { onMounted, ref, nextTick } from 'vue';
const col = ref([{label: '日期',prop: 'date'},{label: '姓名',prop: 'name'},{label: '地址',prop: 'address'}
]);const tableData = ref([{date: '2016-05-03',name: '建筑电工',address: '天河区'},{date: '2016-05-02',name: '管道工',address: '番禺区'},{date: '2016-05-04',name: '木工',address: '越秀区'},{date: '2016-05-01',name: '架子工',address: '海珠区'}
]);onMounted(() => {// 阻止默认行为document.body.ondrop = function (event) {event.preventDefault();event.stopPropagation();};rowDrop();columnDrop();
});
//行拖拽
const rowDrop = () => {const tbody = document.querySelector('.el-table__body-wrapper tbody');Sortable.create(tbody, {onEnd({ newIndex, oldIndex }) {if (newIndex == oldIndex) return;tableData.value.splice(newIndex, 0, tableData.value.splice(oldIndex, 1)[0]);const newArray = tableData.value.slice(0);tableData.value = [];nextTick(function () {tableData.value = newArray;});}});
};
//列拖拽
const columnDrop = () => {const wrapperTr = document.querySelector('.el-table__header-wrapper tr');Sortable.create(wrapperTr, {animation: 180,delay: 0,onEnd: (evt) => {const oldItem = col.value[evt.oldIndex];col.value.splice(evt.oldIndex, 1);col.value.splice(evt.newIndex, 0, oldItem);const newArray = col.value.slice(0);col.value = [];nextTick(function () {col.value = newArray;});}});
};
</script><style scoped>
.home {font-size: 36px;
}
</style>

4、列表的拖拽排序
列表拖拽排序一般只用在行的拖拽排序，此处我们依旧可以使用sortableJs来实现拖拽排序的功能，具体代码如下

<template><div class="home"><div style="width: 800px"><ul id="items"><li v-for="item in listData" :key="item.id" class="item">{{ item.name }}</li></ul></div></div>
</template><script setup>
import Sortable from 'sortablejs'; //引入插件
import { onMounted, ref, nextTick } from 'vue';
const listData = ref([{id: 1,name: '数据一'},{id: 2,name: '数据二'},{id: 3,name: '数据三'},{id: 4,name: '数据四'}
]);
onMounted(() => {// 阻止默认行为document.body.ondrop = function (event) {event.preventDefault();event.stopPropagation();};rowDrop();
});
//行拖拽
const rowDrop = () => {const tbody = document.getElementById('items');Sortable.create(tbody, {onEnd({ newIndex, oldIndex }) {if (newIndex == oldIndex) return;listData.value.splice(newIndex, 0, listData.value.splice(oldIndex, 1)[0]);const newArray = listData.value.slice(0);listData.value = [];nextTick(function () {listData.value = newArray;console.log(listData.value);});}});
};
</script><style scoped>
.item {border: 1px solid #a7a2a2;padding: 10px;
}
</style>
