reactjs - 如何为 Material UI 的 TableHead 赋予圆角

Question

我正在使用 React 和 Material UI，我试图为表格的标题提供 10px 的 broder-radius，以便只有 TableHead 有圆角。
问题是边界半径似乎在 TableHead 上根本不起作用，如您在此屏幕截图中所见:
代码(取自官方文档，我只是在 TableHead 中添加了样式):

<TableContainer>
  <Table aria-label="customized table">
    <TableHead style={{ backgroundColor: '#E2E2E2', borderRadius: '10px' }}>
      <TableRow>
        <TableCell>Dessert (100g serving)</TableCell>
        <TableCell align="right">Calories</TableCell>
        <TableCell align="right">Fat&nbsp;(g)</TableCell>
        <TableCell align="right">Carbs&nbsp;(g)</TableCell>
        <TableCell align="right">Protein&nbsp;(g)</TableCell>
      </TableRow>
    </TableHead>
    <TableBody>
      {rows.map((row) => (
        <TableRow key={row.name}>
          <TableCell component="th" scope="row">
            {row.name}
          </TableCell>
          <TableCell align="right">{row.calories}</TableCell>
          <TableCell align="right">{row.fat}</TableCell>
          <TableCell align="right">{row.carbs}</TableCell>
          <TableCell align="right">{row.protein}</TableCell>
        </TableRow>
      ))}
    </TableBody>
  </Table>
</TableContainer>;

我如何完成这项工作？

据我所知，没有办法为整个 tablerow 设置 border-radius，但是可以通过为第一个和最后一个单元格使用单独的半径来解决问题:

const { Table, TableBody, TableCell, TableContainer, TableHead, TableRow, Paper, makeStyles } = MaterialUI

const useStyles = makeStyles((theme) => ({
  table: {
    minWidth: 400,
  },
  thead: {
    backgroundColor: 'lightgray',
    '& th:first-child': {
      borderRadius: '1em 0 0 1em'
    },
    '& th:last-child': {
      borderRadius: '0 1em 1em 0'
    }
  }
}))

function createData(name, calories, fat, carbs, protein) {
  return { name, calories, fat, carbs, protein }
}

const rows = [
  createData('Frozen yoghurt', 159, 6.0, 24, 4.0),
  createData('Ice cream sandwich', 237, 9.0, 37, 4.3),
  createData('Eclair', 262, 16.0, 24, 6.0),
  createData('Cupcake', 305, 3.7, 67, 4.3),
  createData('Gingerbread', 356, 16.0, 49, 3.9),
]

const App = function () {
  const classes = useStyles()

  return (
    <TableContainer component={Paper}>
      <Table className={classes.table} aria-label="customized table">
        <TableHead classes={{ root: classes.thead }}>
          <TableRow>
            <TableCell>Dessert (100g serving)</TableCell>
            <TableCell align="right">Calories</TableCell>
            <TableCell align="right">Fat (g)</TableCell>
            <TableCell align="right">Carbs (g)</TableCell>
            <TableCell align="right">Protein (g)</TableCell>
          </TableRow>
        </TableHead>
        <TableBody>
          {rows.map((row) => (
            <TableRow key={row.name}>
              <TableCell component="th" scope="row">{row.name}</TableCell>
              <TableCell align="right">{row.calories}</TableCell>
              <TableCell align="right">{row.fat}</TableCell>
              <TableCell align="right">{row.carbs}</TableCell>
              <TableCell align="right">{row.protein}</TableCell>
            </TableRow>
          ))}
        </TableBody>
      </Table>
    </TableContainer>
  )}

ReactDOM.render(<App />, document.getElementById('root'))
