設置width為一些適當的大值（例如500px），并white-space: nowrap在.rightPaneItem.
請記住，元素的width屬性值.rightPaneItem需要根據rightPaneItem最長內容的內容進行調整。
function App() {
return (
<div className="App">
<div className="leftPane">
LeftPane
{new Array(100).fill(0).map((_, i) => (
<div key={i} class="leftPaneItem">
item {i}
</div>
))}
</div>
<div className="rightPane">
RightPane
{new Array(100).fill(0).map((_, i) => (
<div key={i} class="rightPaneItem">
item {i} with a way longer text so you should be able to scroll
horizontally
</div>
))}
</div>
</div>
);
}
ReactDOM.render(<App />, document.getElementById("root"));
.App {
text-align: center;
max-height: 300px;
max-width: 300px;
display: flex;
border: 3px dashed green;
overflow: auto;
padding: 5px;
}
.leftPane {
display: flex;
flex-direction: column;
height: 100%;
flex: 1;
border: 2px solid red;
padding: 5px;
}
.rightPane {
display: flex;
flex-direction: column;
height: 100%;
flex: 2;
border: 2px solid blue;
padding: 5px;
overflow-x: auto;
}
.leftPaneItem {
height: 20px;
}
.rightPaneItem {
height: 20px;
width: 500px;
overflow-x: hidden;
white-space: nowrap;
}

由于您將在右列中擁有可變長度的內容，因此您可以使用以下方法。
您可以在外部容器和元素上添加，而不是在 上設置width和overflow屬性。.rightPaneItemoverflow: auto.App.rightPane
function App() {
return (
<div className="App">
<div className="leftPane">
LeftPane
{new Array(100).fill(0).map((_, i) => (
<div key={i} class="leftPaneItem">
item {i}
</div>
))}
</div>
<div className="rightPane">
RightPane
{new Array(100).fill(0).map((_, i) => {
if (i % 2 == 0) {
return (
<div key={i} class="rightPaneItem">
item {i} with a way longer text so you should be able to scroll
horizontally
</div>);
} else {
return (
<div key={i} class="rightPaneItem">
item {i} with a way longer text so you should be able to scroll
horizontally. item {i} with a way longer text so you should be able to scroll
horizontally. item {i} with a way longer text so you should be able to scroll
horizontally
</div>);
}
})}
</div>
</div>
);

我還在 codesandbox 上創建了一個演示，它類似于您問題中發布的演示，并使用與第二個代碼片段中使用的相同的 CSS。
