element table表格合并

    //计算同列中相同元素，并放入list中
getList(data) {
      for (var i = 0; i < data.length; i++) {
        console.log(data[i])
        if (i === 0) {
          this.list.push(1);
          this.number = 0
        } else {
          // 判断当前元素与上一个元素是否相同
          if (data[i].equipment === data[i - 1].equipment) {
            this.list[this.number ] += 1;
            this.list.push(0);
          } else {
            this.list.push(1);
            this.number = i;
          }
        }
