Problemas com cabeçalho no layout de página de duas colunas

Problemas com cabeçalho no layout de página de duas colunas

Quero criar um dicionário usando o layout de página de duas colunas, mas ocorrem alguns problemas inesperados ao formatar o cabeçalho das páginas. Os problemas relacionados ao cabeçalho são descritos a seguir:

  1. Como remover o cabeçalho da coluna no início de cada página da coluna esquerda? A imagem está a seguir:

  1. Como elevar o cabeçalho do lado direito nas páginas pares e o cabeçalho do lado esquerdo nas páginas ímpares para uma posição mais alta? Veja as seguintes fotos:

  1. Como adicionar marcadores (mudar para todas as letras maiúsculas, como A, B, C, etc. na posição inicial de cada grupo de palavras) no documento PDF de saída. Para ser mais preciso, quando abro a saída através do Acrobat Adobe Pro não consegui encontrar os marcadores no lado esquerdo. Já carreguei o pacote hyperref, porém não funcionou.

O exemplo mínimo de trabalho é:

Responder2

Ajustei o código e acabei resolvendo o problema de formatação do cabeçalho. Se não definirmos uma regra principal decorativa global pelo comando renewcommandou pela definição interna do Tex, \makeatleter \define\headrule{...}\makeatotherentão esta regra principal decorativa não aparecerá como um cabeçalho da coluna esquerda. Isso resolve a segunda questão. Por outro lado, podemos controlar o levantamento ou eliminação do cabeçalho esquerdo e direito de toda a página (que contém duas colunas) usando o comando \raisebox{\leftmark or \rightmark}. Isso resolve a primeira questão. Meu código Tex aprimorado é o seguinte:
