获取其他列的数据
{
    title: '价格(元)',
    align: "center",
    dataIndex: '',
    scopedSlots: { customRender: 'price' },
    // customRender: (text, record) => {
    //     if (record.priceType == '1') {
    //         return record.price;
    //     } else if (record.priceType == '2') {
    //         return record.price + " - " + record.price2;
    //     } else if (record.priceType == '3') {
    //     ...
    //     }
    // }
},

若要添加样式

{
    title: '价格(元)',
    align: "center",
    dataIndex: '',
    scopedSlots: { customRender: 'price' }
},

在a-table中

<a-table
  ref="table"
  size="middle"
  bordered
  rowKey="id"
  :columns="columns"
  :dataSource="tableList"
  :pagination="ipagination"
  :loading="loading"
  class="j-table-force-nowrap"
  :rowSelection="{selectedRowKeys: selectedRowKeys, onChange: onSelectChange}"
  @change="handleTableChange">

<span slot="price" slot-scope="text, record">
  <span v-if="record.priceType  == '1'">
    <span>{{record.price}}</span>
  </span>
  <span v-if="record.priceType  == '2'">
    {{record.price}} - {{record.price2}}
  </span>
  <span v-if="record.priceType  == '3'">
    <span style="text-decoration:line-through">{{record.price}}</span>(原价)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{{record.price2}}(现价)
  </span>
