【React Window】 可以实现列表的懒加载吗？

你可以使用https://npmjs.com/package/react-window-infinite-loader来实现：

import { FixedSizeList as List } from "react-window";
import InfiniteLoader from "react-window-infinite-loader";

    <InfiniteLoader
        isItemLoaded={isItemLoaded}
        itemCount={1000}
        loadMoreItems={loadMoreItems}
      >
        {({ onItemsRendered, ref }) => (
          <List
            className="List"
            height={150}
            itemCount={1000}
            itemSize={30}
            onItemsRendered={onItemsRendered}
            ref={ref}
            width={300}
          >
            {Row}
          </List>
        )}
      </InfiniteLoader>
