vue 获取数组最大值

let list = [];
          data.forEach((element) => {
            tableData.value.push(element);
            let flag = list.findIndex(item => item == element.sortId);
            if (flag == -1) {
              list.push(element.sortId);
            }
          });
          maxSortId.value = Math.max.apply(null, list);
