vue-cli 接口返回数据key为id 不能被iview的表格渲染，关键字id冲突，更改key值

addcate(){
        let that = this;
        console.log(this.catename);
        this.$http.post('http://127.0.0.1/tp51/public/index/cate/addcate', {
              catename:this.catename
          }).then(function (response) {
              console.log(response.data);
  //          that.data6 = response.data;
          }).catch(function (error) {
        });
      },
