直接上代码:

<template>
  <div style="padding:15px;">
    <h3 style="text-align: left; padding:10px; background: #ccc;">
      vue+element-ui+sortable.js表格行和列拖拽
    </h3>
    <div style="width: 55%; margin-right:4%; float: left;">
      <el-table :data="tableData"
                border
                row-key="id"
                align="left"
                @cell-click="cellClick">
        <el-table-column type="selection" align="center"></el-table-column>
        <el-table-column
          v-for="(item, index) in colList"
          :key="index"
          :prop="item.prop"
          :label="item.label"
          class-name="move"
          align="center">
            <!--核心代码: 让列内容跟着列头调整-->
            <template slot-scope="scope">
              <p>{{ scope.row[dropCol[index].prop] }}</p>
            </template>
        </el-table-column>
      </el-table>
    </div>
    <div style="width: 40%; float: left; border:1px solid #ccc;">
            <pre style="text-align: left">
