element-ui表格功能实现(删除选中)

   del() {
      [...this.multipleSelection.map((n) => n.__ob__.dep.id)].forEach(
        (n) => {
          this.gridData.some((item, index) => {
            if (item.__ob__.dep.id == n) {
              this.gridData.splice(index, 1);
              return true;
            } else return false;
          });
        }
      );
    },
