vue如何使用element ui表格el-table-column在里面做判断

//第一种
 <el-table-column prop="status"
                         label="样本状态"
                         width="180">
          <template slot-scope="scope">
            <span v-show="scope.row.status==1">已取样</span>
            <span v-show="scope.row.status==2">实验室处理中</span>
            <span v-show="scope.row.status==3">测序中</span>
            <span v-show="scope.row.status==3">数据分析中</span>
            <span v-show="scope.row.status==3">已完成</span>
          </template>
        </el-table-column>
 
//第二种
<el-table-column prop="type"
                         label="样本类型"
                         :formatter="sample">
          <!-- <template slot-scope="scope">
            <span v-show="scope.row.type==1">血液</span>
            <span v-show="scope.row.type==2">尿液</span>
            <span v-show="scope.row.type==3">唾液</span>
          </template> -->
        </el-table-column>
 
sample(row, column, cellValue) {
      if (cellValue == '1') {
        return '血液'
      } else if (cellValue == '2') {
        return '尿液'
      } else {
        return '唾液'
      }
    },
