vue 中 elment-ui table合并上下两行相同数据单元格
html ：
<el-table
:header-cell-style="{background:'#6d7f93',color:'white'}"
:data="ptableDate"
align="center"
border
v-loading="loading"
:height="tableHeight"
:span-method="objectOneMethod"
>
<el-table-column align="center" show-overflow-tooltip prop="projName" ></el-table-column>
<el-table-column align="center" show-overflow-tooltip prop="dirtySection" ></el-table-column>
<el-table-column align="center" show-overflow-tooltip prop="towerNumber" ></el-table-column>
<el-table-column align="center" show-overflow-tooltip prop="inclination" ></el-table-column>
</el-table>
