Answer 1

Modify your code and move tr / /tr outside second for loop:

<table>
<?php
for($row=0;$row<3;$row++){?>
    <tr>  <!-- Open tr here -->
    <?php
    for($cols=0;$cols<3;$cols++){?>
        <td><?php echo rand(0, 10); ?></td>
    <?php
    }?>
    </tr>  <!-- Close tr here -->
<?php
    }?>
</table>
