get dynamic content by name in PHP [duplicate]

am looking for a way to output the dynamic content data by first_name (fn)

this index

the results are displayed

i want the result to be displayed like this

this html

<table class="my-2" border='0' width='100%'>
<tr style='color:#fff;' >
<td>First Name</td>
<td>Last Name</td>
<td>Last Update</td>
<td>Devisi</td>
<td>View</td>
</tr>
<?php 
$query = "SELECT d1.id,last_name,first_name FROM customers d1
INNER JOIN
(SELECT MAX(id) AS id FROM customers GROUP By first_name ) AS P ON (d1.ID=P.ID) ORDER BY id DESC";
$result = mysqli_query($con,$query);
while($row =mysqli_fetch_assoc($result))
{   
$id=$row['id'];
$fn=$row['first_name'];
$ln=$row['last_name'];
echo "<tr style='color:#fff;'>";
echo "<td border='0' width='20%'>".$fn;"</td>";
echo "<td border='0' width='20%'>".$ln;"</td>";
echo "<td border='0' width='20%'></td>";
echo "<td border='0' width='20%'></td>";
echo "<td border='0' width='20%'><button data-id='".$fn."' class='btn btn-warning my-2 nameinfo'>Data</button></td>";
echo "</tr>";
}
?>
</table>

Javascript

 $(document).ready(function(){
    $('.nameinfo').click(function(){
         var fn = $(this).data('fn');
         $.ajax({
               url: 'ajx.php',
               type: 'post',
               data: {fn: fn},
               success: function(response){
                   $('.modal-body').html(response);
                    $('#empModal').modal('show'); 
               },
         });
    });
});

this is my code of ajx.php

<?php
include "db.php";

$fn = 0;
if(isset($_POST['fn'])){
    $fn = mysqli_real_escape_string($con,$_POST['fn']);
}

$sql = "select first_name, last_name from customers where first_name=".$fn;
$result = mysqli_query($con,$sql);


while( $row = mysqli_fetch_array($result) ){
    ?>
    <table border='0' width='100%'>
    <tr>
    <td width="50%"><?php echo $row['first_name'];?></td>
    <td><?php echo $row['last_name'];?></td>
    </tr>
    </table>
    <?php
}

?>
