Is extending Zend_Db_Table to read the Prefix from the Registry a better approach than using Zend_Registry directly?

Extending Zend_Db_Table to read the Prefix from the Registry can be a better approach as it encapsulates the logic within the class itself, making it more modular and easier to maintain. By doing this, the Zend_Db_Table class becomes more self-contained and does not rely directly on the global Zend_Registry, improving code organization and separation of concerns. 

class My_Db_Table extends Zend_Db_Table_Abstract
{
    protected $_prefix = '';

    public function __construct($config = array())
    {
        if (Zend_Registry::isRegistered('prefix')) {
            $this->_prefix = Zend_Registry::get('prefix');
        }

        parent::__construct($config);
    }

    public function getTableName()
    {
        return $this->_prefix . parent::getTableName();
    }
}
