vue数据渲染问题，使用this.$set和this.$forerUpdate都无效

vue数据渲染问题，使用this.$set和this.$forerUpdate都无效，使用this.$forerUpdate可以看见值被改变页面但是不渲染，是用 = 和 this.$set赋值值根本不带动的

页面事件，ui是ANT V ，

<span slot="processName" slot-scope="row">
    <a-auto-complete
              v-model="editTableData[row.index].processName"
              :data-source="dataSourceComponent"
              placeholder="  请选择工序名"
              @dblclick.native="onProcessNameClick"
              @blur="onProcessNameSelect(row.index,editTableData[row.index].processName)"
              @select="onProcessNameSelect(row.index,editTableData[row.index].processName)"
              @search="onProcessNameSearch"
          />
</span>

js如下

onProcessNameSelect(index, value) {
      console.log(this.categoryProcessPriceList)
      let result = true
      for (let i = 0; i < this.categoryProcessPriceList.length; i++) {
        if (this.categoryProcessPriceList[i].processName == value) {
            this.editTableData[index].processName = this.categoryProcessPriceList[i].processName
            this.editTableData[index].processNum = this.categoryProcessPriceList[i].gxxh
            this.editTableData[index].processCode = this.categoryProcessPriceList[i].processCode
            this.editTableData[index].price = this.categoryProcessPriceList[i].labourCost
            this.editTableData[index].isPrice = true
            result = false
        }
      }
      if(result){
          //上面的赋值完全没问题，进入下面的方法后，上面的赋值也会出现问题
          // this.editTableData[index].price = ""
          // this.editTableData[index].processName = value
          // this.editTableData[index].processNum = ""
          // this.editTableData[index].processCode = ""
          // this.editTableData[index].isPrice = false
          this.$set(this.editTableData[index],"price",0)
          this.$set(this.editTableData[index],"processName",value)
          this.$set(this.editTableData[index],"processNum","")
          this.$set(this.editTableData[index],"processCode","")
          this.$set(this.editTableData[index],"isPrice",false)
          // this.editTableData[index].processName = value
          // this.editTableData[index].processNum = ""
          // this.editTableData[index].processCode = ""
          // this.editTableData[index].isPrice = false
          this.$forceUpdate()
      }
    },
