<script setup>
import { onMounted, ref } from "vue";
import Sortable from "sortablejs";

const tableData = ref([
  {
    id: 1,
    date: "2016-05-02",
    name: "王小虎111",
    age: 21,
    address: "上海市普陀区金沙江路 1518 弄",
  },

    ghostClass: "target-row-class",
    // 结束拖拽后的回调函数
    onEnd({ newIndex, oldIndex }) {

      data.splice(newIndex, 0, currentRow);
    },
  });
}
</script>

<template>
  <el-table
    ref="table"
    :data="tableData"
