使用场景分析，要求提交数据表中修改的某行数据，实时刷新该行数据的状态，该行的某条属性是根据条件渲染的。

el-table部分：

<el-table-column label="关联状态" width="100">
   <template slot-scope="scope"> 
       <el-tag
          :type="scope.row.status === 'true' ? 'success' : 'info'"
          disable-transitions>{{scope.row.status === 'true' ? '显示' : '禁止'}}                                                        
       </el-tag>      
   </template>
</el-table-column>

js部分

//手动改变表单值
this.tableData[index].tag = !this.tableData[index].tag
//利用vue的$set方法进行更新表格数据
this.$set(this.tableData, index, row);
