Try like this:

<?php $arr = range(1, 50); ?>

<table border="1">
    <?php for ($k = 0; $k < count($arr); $k++): ?> 
        <tr>
            <?php for ($i = 0; $i < count($arr); $i++): ?>
                <td><?php echo ($i - 1 === $k || $i === 0) ? '+' : '' ?></td>
            <?php endfor; ?>
        </tr>
    <?php endfor; ?>
