element ui + sortablejs实现表格的行列拖拽

<template>
  <div class="container">
    <el-table :data="tableData" border row-key="id">
      <el-table-column
        align="center"
        v-for="(item, index) in col"
        :key="`col_${index}`"
        :prop="dropCol[index].prop"
        :label="item.label"
      ></el-table-column>
    </el-table>
  </div>
</template>

注意: 当一个页面有多个表格时候 选择器 换成 querySelectorAll 做对应的判断处理即可；
