三层结构的数据显示到表格中合并表格行

表格添加合并方法

在接口中拿到数据并处理数据，接口返回的数据格式

处理数据，处理完的表格数据的结构和正常表格数据结构一样，声明length1，length2，啊，来判断表格第一列和第二列的数据应该合并多少行

表格

getcompareObjResult() {

const query = {

hisid: this.$route.params.hisId

}

compareObjResult(query).then(res => {

const temp = res.data.data

const targetList = []

const length1 = [0]

const length2 = [0]

let a

temp.forEach(item => {

const dbinfo = item

const dblist = item.DETAIL

// const rowCount = item.DETAIL.length

a = 0

dblist.forEach((item2, index) => {

item2.TABLE = dbinfo.TABLE

const dbinfo2 = item2

const dblist2 = item2.DETAIL

// const rowCount2 = item2.DETAIL.length

// console.log(dblist2, 7777777777)
