If you’re looking to use an ACF repeater to create an HTML table, here’s how I do it. The ACF function get_field_objects() is used in the post or page template in this case. Dump it out to see what’s in there.
<?php $table = get_field_objects(); ?>
<table class="table">
<thead>
<tr>
<th>First</th>
<th>Last</th>
<th>Phone</th>
<th>Email</th>
<th>Address</th>
<th>Joined</th>
</tr>
</thead>
<tbody>
<?php foreach ($table['directory_table']['value'] as $row) : ?>
<tr>
<td><?= $row['first'] ?></td>
<td><?= $row['last'] ?></td>
<td><?= $row['phone'] ?></td>
<td><?= $row['email'] ?></td>
<td><?= $row['address'] ?></td>
<td><?= $row['joined'] ?></td>
</tr>
<?php endforeach ?>
</tbody>
</table>
