如何让相邻列的span标签高度自动撑开，即使单元格内容高度不一致？

<el-row class="row">
  <el-col class="col">
    <span class="label">上平行度</span>
    <span class="value"></span>
  </el-col>
  <el-col class="col">
    <span class="label">平行度OK/NG</span>
    <span class="value"></span>
  </el-col>
</el-row>

.row {
  border-bottom: solid .0625rem #9c9c9c;
  display: flex;
  align-items: center;
  justify-content: center;

  .col {
    height: 100%;
    display: flex;
    span:not(:last-child) {
      border-right: solid .0625rem #9c9c9c;
    }
    ::v-deep span {
      flex: 1;
      height: 100%;
      word-break: break-all;
      word-wrap: break-word;
      height: 23px;
      line-height: 23px;
    }
    .label {
      background-color: #e0e0e0;
      color: #000000;
      font-weight: bold;
      height: auto;
    }
    .value {
      height: auto;
    }
  }
}

.row {
  align-items: stretch;
}

.col {
  height: unset;
}

.label {
  display: flex;
  align-items: center;
}
