Let me assume you having the result set as the following array. Try like this

<?php       
    $table = array( 
                        0  => array(
                            'batch_id' => 1 ,
                            'time_start' => '4:30 PM',
                            'time_end' => '5:30 PM',
                            'day' => 'Monday'
                        ),
                        1  => array(
                            'batch_id' => 2 ,
                            'time_start' => '5:30 PM',
                            'time_end' => '6:30 PM',
                            'day' => 'Monday'
                        ),
                        2  => array(
                            'batch_id' => 1 ,
                            'time_start' => '4:00 PM',
                            'time_end' => '5:00 PM',
                            'day' => 'Tuesday'
                        )
        );

    //Arrange the array according to the batch number       
    $arrange_array = array();
        foreach($table as $vals){
            $arrange_array[$vals['batch_id']][] = $vals;            
        }    
?>

<table>
    <tr>
        <th>
            <div><?php echo 'Batch Code'; ?></div>
        </th>
        <th>
            <div><?php echo 'Mon'; ?></div>
        </th>
        <th>
            <div><?php echo 'Tue'; ?></div>
        </th>
        <th>
            <div><?php echo 'Wed'; ?></div>
        </th>
        <th>
            <div><?php echo 'Thu'; ?></div>
        </th>
        <th>
            <div><?php echo 'Fri'; ?></div>
        </th>
        <th>
            <div><?php echo 'Sat'; ?></div>
        </th>
        <th>
            <div><?php echo 'Sun'; ?></div>
        </th>
    </tr> 

    <?php 
        foreach($arrange_array as $key => $days){
            echo '<tr>
                     <td>'.$key.'</td>';                         
                    foreach($days as $batch){
                        echo '<td>'.$batch['time_start'].' - '.$batch['time_end'].'</td>';
                    }                       
            echo  '</tr>';
        }       
    ?>                  
</table>
