Open a link in a child window - php

Question

when either Project or No is clicked, they open in a new window with other details under that clicked row, but i want them to open in a child window instead. is there a way to do it?
this is my code
<table id="keywords" class="container">
<thead>
<tr>
<td><span>Project</span></td>
<td><span>No</span></td>
<td><span>Sub ID</span></td>
<td><span>Name</span></td>
<td><span>Requested Amount</span></td>
<td><span>Paid Amount</span></td>
<td><span>Amount To be Paid</span></td>
<td><span>Description</span></td>
<td><span>State</span></td>
</tr>
</thead>
<?php
/* showing table */
$sql = "SELECT * FROM memo ORDER BY No DESC, SubID ASC"
or die("Failed to query database" .mysqli_error());
$result = $link->query($sql);
while ($row = $result->fetch_assoc()) {
print "<tr>";
print "<td >" . $row['Project'] . "</td>";
print "<td >" . $row['No'] . "</td>";
print "<td >" . $row['SubID'] . "</td>";
print "<td >" . $row['Name'] . "</td>";
print "<th >" . $row['RequestAmount'] . "</th>";
print "<th >" . $row['PaidAmount'] . "</th>";
print "<th >" . $row['AmountToPay'] . "</th>";
print "<td >" . $row['Description'] . "</td>";
print "<td >" . $row['State'] . "</td>";
print "</tr>";
}
// print "</table>";
?>
