使用 InfiniteLoader、Table、Column、AutoSizer 和 CellMeasurer 构建响应式无限滚动 table
Building a responsive infinite scroll table with InfiniteLoader, Table, Column, AutoSizer, and CellMeasurer
我刚刚完成了使用 InfiniteLoader、Table、Column 和 AutoSizer 的工作 table,我意识到这 table 不能随浏览器水平缩放 window。尽管图书馆的大部分内容都有很好的记录,但我还是花了很长时间才开始工作。我想要实现的是像 table 这样的 HTML,它根据浏览器 window 的宽度调整大小,随着内容换行垂直增加行高,并使用具有不同行高的无限加载。反应虚拟化是否可以实现所有这些点?最好先问一下,因为组合这个库的所有移动部分可能很棘手。谢谢!
这是我的组件:

import { InfiniteLoader, Table, Column, AutoSizer } from 'react-virtualized';
import { connect } from 'react-redux';
import { CSSTransitionGroup } from 'react-transition-group';

import Footer from './footer';
class ProspectsTable extends React.Component {
constructor(props, context) {
super(props, context);
this.renderProspects = this.renderProspects.bind(this);
this.isRowLoaded = this.isRowLoaded.bind(this);
this.loadMoreRows = this.loadMoreRows.bind(this);
this.rowRenderer = this.rowRenderer.bind(this);
this.state = {
remoteRowCount: 200,

isRowLoaded({ index }) {
return !!this.state.list[index];
}

return fetch(`http://localhost:5001/api/prospects?startIndex=${startIndex}&stopIndex=${stopIndex}`)
.then((response) => {
console.log('hi', response);
console.log('hi', this.props);
});
}
rowRenderer({ key, index, style }) {
return (
<div
key={key}
style={style}
>
{this.state.list[index]}
</div>
);
}
render() {
return (

{({ onRowsRendered, registerChild }) => (

<AutoSizer>
{({ width }) => (

<Column

<Column

<Column

</Table>
)}

)}
</InfiniteLoader>
);
}
}
}
const mapStateToProps = state => ({

export default connect(mapStateToProps)(ProspectsTable);
这是一个与我的代码非常相似的 plnkr,我经常引用它:https://plnkr.co/edit/lwiMkw?p=preview
到目前为止,在一个雄心勃勃的项目上做得很好。关于实现剩余目标的一些想法:
Resizes based on the browser window's width
尝试将您的 AutoSizer
组件置于此层次结构的顶层,并确保其父组件的宽度随视口而变化。这可以像父 div
和 width: 100vw
.
一样简单地实现
grows row heights vertically as content wraps, and uses infinite load with varying row heights
这些都可以通过根据数据动态设置行高来实现。来自 Table
的 rowHeight
道具上的 docs:
Either a fixed row height (number) or a function that returns the height of a row given its index: ({ index: number }): number
React-Virtualized 通过提前计算其维度来发挥其魔力,因此您将无法获得 flex-wrap
功能或其他基于 CSS 的解决方案以正常工作。相反,确定如何使用给定行的数据(可能还有当前屏幕尺寸)来计算该行的高度。例如:
const BASE_ROW_HEIGHT = 30;
const MAX_NAME_CHARS_PER_LINE = 20;
...
getRowHeight = ({ index }) => {
const data = this.state.list[index];
// Not a great example, but you get the idea;
// use some facet of the data to tell you how
// the height should be manipulated
const numLines = Math.ceil(fullName.length / MAX_NAME_CHARS_PER_LINE);
return numLines * BASE_ROW_HEIGHT;
};
render() {
...
<Table
...
rowHeight={this.getRowHeight}
>
}
作为额外的参考,我发现 React-Virtualized Table
example 的源代码非常有用——尤其是关于动态设置行高的行:
_getRowHeight({ index }) {
const { list } = this.context;
return this._getDatum(list, index).size;
}
祝你好运!
