数据格式差不多这样的

渲染后：

现在需要将红色框里面分多行行显示

Answer 1

你这种，我建议直接在一个单元格里用v-for渲染多div，然后调一调样式，可以达到你想要的效果，这是最简单的

Answer 2

有没有类似合并单元格内种的，想用js实现下

Answer 3

有，但是这是多条数据合并成一个，当时你想一条数据分成多个，我不知道行不行。或者你可以研究下

Answer 4

<el-table-column label="地址" prop="address">
        <template slot-scope="{row}">
          <div v-if="Array.isArray(row.address)">
                            <p v-for="(adr, index) in row.address" :key="index">{{adr}}</p>
                    </div>
                    <span v-else>{{row.address}}</span>
        </template>
</el-table-column>

这种方式它不香吗？
