It looks like you have several repeaters rather than a single repeater. You will need to check each repeater to see if it has anything before creating the <table></table>

There are a couple ways that you can do this

1

<?php

if( get_field('product_watts') && get_field('product_watt_replacement')) {
echo '<table>';

if( get_field('product_watts') ) {

    echo '<tr><td>' . '<strong>Wattage: </strong></td><td>'; 
    while ( have_rows('product_watts') ) : the_row();
    	 $array1[] = get_sub_field('watts')  .'w'; 
    endwhile;
    	$watts = implode(', ', $array1);

    echo $watts .'</td></tr>'; 
}

if( get_field('product_watt_replacement') ) {

    echo '<tr><td>' . '<strong>Wattage Replacement: </strong></td><td>'; 
    while ( have_rows('product_watt_replacement') ) : the_row();
    	 $array2[] = get_sub_field('watt_replacement')  .'w'; 
    endwhile;
    	$watt = implode(', ', $array2);

    echo $watt .'</td></tr>'; 
}

echo '</table>';
} // end if all fields have values

?>

The other way would be to loop though each field and build the html and then test to see if there is any content, something like this

<?php

$content = '';
if( get_field('product_watts') ) {

    $content .= '<tr><td>' . '<strong>Wattage: </strong></td><td>'; 
    while ( have_rows('product_watts') ) : the_row();
    	 $array1[] = get_sub_field('watts')  .'w'; 
    endwhile;
    	$watts = implode(', ', $array1);

    $content .=  $watts .'</td></tr>'; 
}

if( get_field('product_watt_replacement') ) {

    $content .=  '<tr><td>' . '<strong>Wattage Replacement: </strong></td><td>'; 
    while ( have_rows('product_watt_replacement') ) : the_row();
    	 $array2[] = get_sub_field('watt_replacement')  .'w'; 
    endwhile;
    	$watt = implode(', ', $array2);

    $content .=  $watt .'</td></tr>'; 
}

if ($contend) {
 echo '<table'>',$content,'</table>';
}
?>
