Bug Report: cell.isGrouped Always Returns false Despite enableGrouping Being true (REACT)

Describe the bug and the steps to reproduce it

Description When using react-table with grouping enabled, cell.isGrouped always returns false, even though enableGrouping is set to true in the column configuration. This issue persists despite ensuring that the table is properly configured for grouping.

Expected Behavior cell.isGrouped should return true for cells in grouped rows when enableGrouping is set to true in the column configuration.

Actual Behavior cell.isGrouped consistently returns false, regardless of the grouping settings.

Kindly have a look on the below example , also let us know are we doing something wrong.

Here is the minimal code example demonstrating the issue:

import React from 'react';
import { useTable, useGroupBy } from 'react-table';

export const TableComponent = ({ columns, data }) => {
  const {
    getTableProps,
    getTableBodyProps,
    headerGroups,
    rows,
    prepareRow,
  } = useTable({ columns, data }, useGroupBy);

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th {...column.getHeaderProps()}>{column.render('Header')}</th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody {...getTableBodyProps()}>
        {rows.map(row => {
          prepareRow(row);
          return (
            <tr {...row.getRowProps()}>
              {row.cells.map(cell => {
                 console.log(cell.isGrouped); // Always false
                return (
                  <td {...cell.getCellProps({
                    className: cell.column.id === 'columnA2' ? 'custom-cell' : ''
                  })}>
                    {cell.render('Cell')}
                  </td>
                );
              })}
            </tr>
          );
        })}
      </tbody>
    </table>
  );
};

export const columnsa = [
  {
    Header: 'Group A',
    enableGrouping: true,
    columns: [
      { Header: 'Column A1', accessor: 'columnA1' },
      { Header: 'Column A2', accessor: 'columnA2' },
    ],
  },
  {
    Header: 'Group B',
    enableGrouping: true,
    columns: [
      { Header: 'Column B1', accessor: 'columnB1' },
      { Header: 'Column B2', accessor: 'columnB2' },
    ],
  },
];

export const data = [
  { columnA1: 'Data A1', columnA2: 'Data A2', columnB1: 'Data B1', columnB2: 'Data B2' },
  { columnA1: 'Data A1', columnA2: 'Data A2', columnB1: 'Data B1', columnB2: 'Data B2' },
];

I am also experiencing this issue, when using the grouping feature, cell.column.getIsGrouped always returns false and cell.column.getGroupedIndex always returns -1. Even on the docs, this Sandbox shows the error, on line 154, if the cell is part of a group it is supposed to have a different background but it doesnt, they all have a white background. Does anyone know a fix for this?
