如何使用映射 React 从 useState 添加 2 个键?

const [marketEstimateDataBCAssets, setmarketEstimateData] = useState([{名称:伦巴第"，prevgroupinputrate: 0.01,currgroup 输入率:0.02，mktratedelta:0.03，mktrateestimate: 0.04},{名称:其他担保"，prevgroupinputrate: 0.01,currgroup 输入率:0.02，mktratedelta:0.033，mktrateestimate: 0.04},{名称:不安全"，prevgroupinputrate: 0.01,currgroup 输入率:0.02，mktratedelta:0.0333，mktrateestimate: 0.04}]);返回 ({marketEstimateDataBCAssets.map((item, key) => {返回 (<段>
{item.name}</div>
{item.prevgroupinputrate}</div>
{item.currgroupinputrate}</div><输入值={item.mktratedelta}onChange={e =>{const newArr = marketEstimateDataBCAssets.map(el => {if (el.name === item.name) {返回 { ...el, mktratedelta: parseFloat(e.target.value) };}返回 el;});控制台.log(newArr);返回 setmarketEstimateData([...newArr]);}}/>
{marketEstimateDataBCAssets[key].mktrateestimate}</div></段>);})} ```

返回 (<>{marketEstimateDataBCAssets.map((item, key) => (<div 键={item.name}>{/* 让我们的名字是唯一的 *
