    Listagem de dados usando recursos avançados da biblioteca DataTables desenvolvida em Jquery. Utilizo a biblioteca, no entanto, preciso usar alguns recursos que não consigo aplicar em meu projeto, como: Atualizar a listagem dos dados parcialmente. As atualizações devem ocorrer cada vez que um novo dado é adicionado ou uma alteração é realizada. Para os dados que são adicionados, uma nova linha deve ser criada, para os dados atualizados, deve-se atualizar a linha existente. O script de atualizar a linha que fiz atualmente, atualiza apenas a linha da página atual e quando tenta atualiza outras linhas, a tabela fica bugada com o script html da linha sendo acrescentada ao final da lista de forma "crua".
