return $content; } add_filter( 'the_content', 'add_product_spec_to_content', 1150 );

You can create a shortcode for this und place it where you want:

function sc_my_table( $atts ) {

    $fields = array(
        'befestigung' => 'Befestigung',
        'gurtsystem' => 'Gurtsystem',
        'bezug' => 'Bezug',
        'gruppe' => 'Gruppe',
        'typ' => 'Typ',
        'gewicht' => 'Gewicht',
        'amazon' => 'Preis',        
    );

    $table_open = false;
    $content = '';

    foreach ( $fields as $field => $name ) {

        if ( $value = get_field( $field ) ) {
            if ( ! $table_open ) {
                $content .= '<table id="product-specification" cellspacing="0" border="0" style="border-collapse:collapse;"><tbody>';
                $table_open = true;
            }

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

    if ( $table_open ) {
        $content .= '</tbody></table>';     
    }

    return $content;

} 

add_shortcode('my-table', 'sc_my_table');

Then use [my-table] in text editor at the desired place.

Reference: add_shortcode()
