Material UI V5 change color of selected row-CodePudding

How can I set one of these table rows as "selected" or "active" and change the font color of the row to red on click? Also when one row is selected, deselect the other rows. I see examples for how to do it with more complex tables and previous versions of MUI but not with a basic table in the current version. Here is the code:

import * as React from 'react';
import Table from '@mui/material/Table';
import TableBody from '@mui/material/TableBody';
import TableCell from '@mui/material/TableCell';
import TableContainer from '@mui/material/TableContainer';
import TableHead from '@mui/material/TableHead';
import TableRow from '@mui/material/TableRow';
import Paper from '@mui/material/Paper';

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 BasicTable() {
  return (
    <TableContainer component={Paper}>
      <Table sx={{ minWidth: 650 }} aria-label="simple table">
        <TableHead>
          <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}
              sx={{ '&:last-child td, &:last-child th': { border: 0 } }}
            >
              <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>
  );
}

edit: I think I need to be more specific. I have read the documentation but am having trouble applying it so that onClick the row is selected and the others are deselected.

CodePudding user response：

You can simply do it by setting the selected property.

You should hole a state for your selected row and then change it on onClick of the table rows:

export default function BasicTable() {
  const [selectedRow, setSelectedRow] = useState(0);
  const handleSelectRow = (rowIndex) => {
    setSelectedRow(rowIndex);
  }

  return (
    <TableContainer component={Paper}>
      <Table sx={{ minWidth: 650 }} aria-label="simple table">
        <TableHead>
          <TableRow selected={selectedRow === 0} onClick={() => handleSelectRow(0)}>
            <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, index) => (
            <TableRow
              key={row.name}
              sx={{ '&:last-child td, &:last-child th': { border: 0 } }}
              selected={selectedRow === index   1}
              onClick={() => handleSelectRow(index   1)}
            >
              <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>
  );
}
