问题描述
我想问一下是否有更简单的方法来显示数据。 这是我的虚拟数据：
const data = [
{
business: false,utilization: {
ActiveParticipantsPercent: 55.55,SeparatedVestedParticipants: 0,ParticipantsWithBenefitaccount: 8,AverageActiveParticipants: 5,TotalContributions: 23890
},year: 2018
},{
business: true,utilization: {
ActiveParticipantsPercent: 82.4,SeparatedVestedParticipants: 1.94,ParticipantsWithBenefitaccount: 95393,AverageActiveParticipants: 0.01,TotalContributions: 257094.79
},year: 2018
}
];
我想在2列中显示数据-一个是具有错误业务价值的2018年，另一个是具有真实业务价值的2018年。 我想为每个人显示利用率字段的数据。
我准备了沙箱以查看其工作方式，但我认为可能有更简便的方法来节省资源：https://codesandbox.io/s/immutable-worker-ixf6r?file=/src/App.js
有什么建议还是应该以这种方式保留？

对象（行）和行内部进行迭代，在数据数组（单元格）之间进行迭代，而不是对每个utilization进行硬编码然后在其中进行迭代>
