% aparecer certa ("Figura 1: ...") mas a entrada na lista aparecer sem o

% Compatibilização do "longtable" com a Lista de Tabelas

% O pacote longtable define seu próprio mecanismo de legenda (\LT@c@ption),
% que grava a entrada na Lista de Tabelas usando \thetable (só o número),
% em vez de \fnum@table ("Tabela"~+~número), diferentemente do \@caption
% padrão usado pelo ambiente "table" (redefinido acima). É por isso que uma
% "tabela normal" mostra o prefixo "Tabela" na lista, mas uma "longtable"
% mostra só o número, criando alinhamento/espaçamento diferente entre as
% entradas. O trecho abaixo corrige isso, trocando \thetable por
% \fnum@table para igualar ao comportamento das tabelas normais.

% Compatibilização do "listings" com a Lista de Códigos
%------------------------------------------------------------------------------

% pelo \@caption customizado da classe, então o prefixo "Código" definido em
% \lstlistingname nunca aparece nessa lista (só no corpo do texto). Aqui
% forçamos o prefixo também na lista, análogo ao que já ocorre com Figura/
% Tabela.
