element el-table 表格列 v-if 显示 隐藏 乱序问题

当tab为投保人时，表格中显示字段为投保人相关信息
当tab为被保人时，表格中显示字段为被保人相关信息
我在来回切换tab时，发现用v-if控制的字段列经常乱序。字段展示先后顺序不一。
如图所示：
解决方法：在table-column中加入:key=“Math.random()” 如下所示代码
<el-table-column
prop="apptPersonName"
label="投保人姓名"
v-if="category===1" :key="Math.random()">
</el-table-column>
<el-table-column
prop="apptCellPhone"
label="投保人手机号"
v-if="category===1" :key="Math.random()">
</el-table-column>
<el-table-column
prop="insuredPersonName"
label="被保人姓名"
v-if="category===0" :key="Math.random()">
</el-table-column>
<el-table-column
prop="insuredCellPhone"
label="被保人手机号"
v-if="category===0" :key="Math.random()">
</el-table-column>
