Question

  list: [
          {

            skuList: [{
                skuName: 'sku名',
                skuNum: 'sku数量'
              },
              {
                skuName: 'sku名1',
                skuNum: 'sku数量1'
              },
              {
                skuName: 'sku名2',
                skuNum: 'sku数量2'
              }
            ],
            collectExpenseList: [{
                expenseName: '费用名称',
                amount: '费用金额'
              },
              {
                expenseName: '费用名称1',
                amount: ''
              },
              {
                expenseName: '费用名称2',
                amount: '费用金额2'
              }
            ]
          },
          {
            enterpriseName: '客户名2',
            skuList: [{
                skuName: 'sku名111111',
                skuNum: 'sku数量'
              },
              {
                skuName: 'sku名1222222',
                skuNum: 'sku数量1'
              },
              {
                skuName: 'sku名2',
                skuNum: 'sku数量2'
              }
            ],
            collectExpenseList: [{
                expenseName: '费用名称',
                amount: '费用金额222'
              },
              {
                expenseName: '费用名称1',
                amount: '费用金额222'
              },
              {
                expenseName: '费用名称2',
                amount: '费用金额222'
              }
            ]
          },
        ],
  this.list.forEach(e => {
        this.collectExpenseList = e.collectExpenseList
        // this.costExpenseList = e.costExpenseList
      })

        <el-table-column v-for="(title,index) in collectExpenseList" :prop="title.prop" :label="title.expenseName"
          align="center" :key="title.prop" :index="title.index" :width="title.width">
          {{ title.amount }}
        </el-table-column>

目前 this.collectExpenseList 只拿到了数组最后一组的数据。应该怎么赋值才是一对一的

Answer 1

 this.list.forEach(e => {
        this.collectExpenseList = e.collectExpenseList
        // this.costExpenseList = e.costExpenseList
      })

你这没有循环添加获取到的只有最后的数据 你把数据push进去
