element ui 计数器 绑定遍历出来的数据 显示问题

Question

数据：
tableData:[{date:'2018-03-02',name:'张三00',num:1},

    {date:'2018-03-02',name:'张三02',num:1},
    {date:'2018-03-02',name:'张三03',num:1},
    ],
    

点击－之后
我做的监听

watch:{

'tableData':{
  handler:function(newValue,oldValue){
    for(let i = this.tableData.length-1;i>=0;i--){
      let v=this.tableData[i]
      if(v.num===0){
        this.tableData.splice(i,1)
        break
      }
    }
  },
  deep:true,
},}

console.log(JSON.stringify(this.tableData))打印数据
[{"date":"2018-03-02","name":"张三00","num":1},{"date":"2018-03-02","name":"张三03","num":1}]

数据是对的
为什么显示不对呢
