this.devicetabledata = res.body || [];
          // console.log("this.devicetabledata", this.devicetabledata);
          //默认全选
          this.$nexttick(() => {
            for (let i = 0; i < this.devicetabledata.length; i++) {
              this.$refs.multipletabledevice.togglerowselection(
                this.devicetabledata[i],
                true
              );
            }
          });

主要是 “

togglerowselection

” 设置
