Ok, well I’ve got something that works now. But as I am a newbie to ACF snippets, I would be very grateful if someone would check this over and let me know how I might improve it. Thanks!

/* Fill empty ACF fields with "blank" so TablePress can hide them */
function set_empty_value( $post_id ) {	
	if ( 'product' != get_post_type($post_id) ) {
      return;
    }
	$fields = get_fields();
	if( $fields ) {
		foreach ( $fields as $name => $value ) {
			if ( $value == '' ) {
				$value = "blank";
				update_field( $name, $value );
			}
		}
	}
}
add_action('acf/save_post', 'set_empty_value', 10, 1 );
