This is just a basic example, I could not copy and alter your code easily because you didn’t use code tags. You need to test the date before you output the table row, I can’t give specifics because that would depend on knowing how the date is being formatted. I am going to assume that dates are returned in the format “Y-m-d”, which would basically be the only way to tell if the date is in the future.
if (have_rows('calender_event', 'option')) {
while (have_rows('calender_event', 'option')) {
$name = get_sub_field('event_name');
$date = get_sub_field('event_date');
$place = get_sub_field('event_place');
$now = date('Y-m-d');
if ($date > $today) {
?>
<tr>
<td>...</td>
<td>...</td>
<td>...</td>
</tr>
<?php
}
} // end while have rows
} // end if have rows
