reactjs - 如何折叠数据表？

Question

我正在尝试折叠 material-ui 中的数据表并仅显示表头以及数据表中的总行数。是否有允许我这样做的数据表插件？

通过获取数组的长度来显示行数......相关的js：

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Table from '@material-ui/core/Table';
import TableBody from '@material-ui/core/TableBody';
import TableCell from '@material-ui/core/TableCell';
import TableHead from '@material-ui/core/TableHead';
import TableRow from '@material-ui/core/TableRow';
import Paper from '@material-ui/core/Paper';
import Badge from '@material-ui/core/Badge';

const useStyles = makeStyles({
  root: {
    width: '100%',
    overflowX: 'auto',
  },
  table: {
    minWidth: 650,
  },
});

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),
];

export default function SimpleTable() {
  const classes = useStyles();

  return (
    <Paper className={classes.root}>
      <Table className={classes.table} aria-label="simple table">
        <TableHead>
          <TableRow>
            <TableCell>
            <Badge className={classes.margin} badgeContent={rows.length} color="primary">
        </Badge>
            </TableCell>            <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 align="right"></TableCell>
              <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>
    </Paper>
  );
}

隐藏在...相关 cssdisplay:none的类上使用的 tbody ：tbody

.MuiTableBody-root{
  display: none;
}
