element+Sortable 实现表格拖拽

<template>
    <div class="draggable" style="padding: 20px">
        <el-table row-key="id" :data="state.tableData" style="width: 100%">
            <el-table-column v-for="(item, index) in state.oldList" :key="`col_${index}`" :prop="state.newList[index].prop"
                :label="item.label" align="center">
            </el-table-column>
        </el-table>
    </div>
</template>
<script setup>
import Sortable from 'sortablejs';
import { reactive, onMounted } from 'vue';

const state = reactive({
    oldList: [],
    newList: [],
    tableData: [
        {
            id: 1,
            name: '李四',
            gender: '男',
            age: 20,
        },
        {
            id: 2,
            name: '王五',
            gender: '未知',
            age: 18,
        },
        {
            id: 3,
            name: '张三',
            gender: '男',
            age: 22,
        },
    ],
    tableConfig: {
        tableItems: [
            {
                label: '姓名',
                prop: 'name',
            },
            {
                label: '性别',
                prop: 'gender',
            },
            {
                label: '年龄',
                prop: 'age',
            },
        ]
    }

})
// 行拖拽
const rowDrop = function () {
    // 要拖拽元素的父容器
    const tbody = document.querySelector('.draggable .el-table__body-wrapper tbody');
    Sortable.create(tbody, {
        //  可被拖拽的子元素
        draggable: ".draggable .el-table__row",
        onEnd({ newIndex, oldIndex }) {
            const currRow = state.tableData.splice(oldIndex, 1)[0];
            state.tableData.splice(newIndex, 0, currRow);
        }
    });
}
// 列拖拽
const columnDrop = function () {
    const wrapperTr = document.querySelector('.draggable .el-table__header-wrapper tr');
    Sortable.create(wrapperTr, {
        animation: 180,
        delay: 0,
        onEnd: evt => {
            const oldItem = state.newList[evt.oldIndex];
            state.newList.splice(evt.oldIndex, 1);
            state.newList.splice(evt.newIndex, 0, oldItem);
        }
    });
}
onMounted(() => {
    state.oldList = JSON.parse(JSON.stringify(state.tableConfig.tableItems))
    state.newList = JSON.parse(JSON.stringify(state.tableConfig.tableItems))
    columnDrop()
    rowDrop()
})
</script>
