Material-UI 是一个流行的 React UI 框架,它基于 Google 的 Material Design 设计规范。带钩子(Hooks)的 Material-UI 收拢表格是指使用 React Hooks 来实现表格的展开和收起功能。
带钩子的 Material-UI 收拢表格通常涉及以下几种类型:
以下是一个简单的带钩子的 Material-UI 收拢表格示例:
import React, { useState } from 'react';
import { Table, TableBody, TableCell, TableContainer, TableHead, TableRow, Paper, IconButton, Typography } from '@material-ui/core';
import { ExpandMore, ChevronDown, ChevronRight } from '@material-ui/icons';
const CollapsibleTable = ({ data }) => {
const [expandedRow, setExpandedRow] = useState(null);
const handleExpandClick = (index) => {
if (expandedRow === index) {
setExpandedRow(null);
} else {
setExpandedRow(index);
}
};
return (
<TableContainer component={Paper}>
<Table>
<TableHead>
<TableRow>
<TableCell>ID</TableCell>
<TableCell>Name</TableCell>
<TableCell>Actions</TableCell>
</TableRow>
</TableHead>
<TableBody>
{data.map((row, index) => (
<React.Fragment key={row.id}>
<TableRow onClick={() => handleExpandClick(index)}>
<TableCell>{row.id}</TableCell>
<TableCell>{row.name}</TableCell>
<TableCell>
{expandedRow === index ? (
<IconButton onClick={() => handleExpandClick(index)}>
<ChevronDown />
</IconButton>
) : (
<IconButton onClick={() => handleExpandClick(index)}>
<ChevronRight />
</IconButton>
)}
</TableCell>
</TableRow>
{expandedRow === index && (
<TableRow>
<TableCell colSpan={3}>
<Typography variant="body2">{row.details}</Typography>
</TableCell>
</TableRow>
)}
</React.Fragment>
))}
</TableBody>
</Table>
</TableContainer>
);
};
export default CollapsibleTable;
expandedRow
状态正确更新。handleExpandClick
函数逻辑是否正确。makeStyles
或 withStyles
)来定制组件样式。react-window
)来优化性能。useMemo
或 useCallback
进行优化。通过以上方法,可以有效地实现和管理带钩子的 Material-UI 收拢表格功能。
