Diferent color for hidden Woocommerce product in admin list

Woocommerce does not support filtering by product visibility. This option is very good for better vision in the product list. With a simple code you add the class to the product. Then with CSS create diferent background-color for product row.

Add this code to your functions.php file in theme folder.

//add class by visible options
add_filter( 'post_class', 'add_my_class_to_post_list' );
function add_my_class_to_post_list( $classes )
{
global $post;
$classes[] = "product-is-".get_post_meta( get_the_ID(), '_visibility', true ) ;
return $classes;
}

//add CSS to admin head
add_action('admin_head', 'my_custom_css');
function my_custom_css()
{
echo '<style>
tr.product-is-hidden { background: linear-gradient(white,red); }
tr.product-is-search {}
tr.product-is-catalog {}
tr.product-is-visible {}
</style>';
}

Result:

You can see, that in CSS code is more class, not just for hidden product. Becouse you can set four type of visibility in product options.
