el-table-column中某个单元的值由该行其他单元格的值决定

 上面的数据在状态中，该单元格的数据不是从后台获取的，而是通过判断当前行中入库日期与当天时间进行对比得出,判断入库日期与当前日期的差值超过3个月就显示超过3个月，入库日期与当前日期的差值超过6个月就显示超过6个月，并且显示颜色还不同

<el-table-column label="状态" header-align="left" align="left" prop="colorStatus" width="140" fixed="right">
          <template slot-scope="scope">
            <span :class="colorFormat(scope.row)"> {
   
   { colorStatusFormat(scope.row) }}</span>
          </template>
        </el-table-column>
