Eu entendi isso

Como posso resolver isso ? estou a usar

\usepackage{booktabs,tabularx}

Answer 1

Sugiro um layout ligeiramente diferente da sua tabela. Como você pode ver no seu exemplo, o texto no primeiro e no segundocolunanão está na mesma linha de base, o que é considerado uma tipografia ruim. Além disso, todas as regras verticais e horizontais são desnecessárias quando você usa sombreamento. Além disso, você obtém linhas brancas espalhadas porque nem \rowcolorand booktabs-rules, nem booktabs-rules e regras verticais são compatíveis. Se o seu tabular fizer parte de um documento, o texto não ficará alinhado nas margens esquerda e direita, o que não é muito bonito.

O código para cancelar o espaço acima dos itens da lista é adaptado do código de David Carlisle emesta resposta.

Aqui está a minha sugestão e, se você estiver interessado, posso explicar as diferentes etapas.

\documentclass{article}
\usepackage{array,booktabs}
\usepackage[table]{xcolor}
\usepackage{enumitem}
\definecolor{darkgrey}{cmyk}{0,0,0,.15}
\usepackage{lmodern, microtype}

\newcolumntype{P}{p{\dimexpr(0.5\linewidth-1em-2\tabcolsep)}}
\newcolumntype{Z}{p{\dimexpr(2em-2\tabcolsep)}}
\newcommand{\listbox}[1]{\parbox[t]{\dimexpr(\linewidth-\tabcolsep)}{\mbox{}\vspace{-\normalbaselineskip\relax}\begin{itemize}[nosep, leftmargin=1em,]#1\end{itemize}}}

\newcommand{\rowspace}{\addlinespace[0.5\normalbaselineskip]}

\setlength{\arrayrulewidth}{3pt}

%%---------------- show page layout. don't use in a real document!

Mais uma solução possível...

• com uso de enumiteme etoolboxlistas de pacotes itemizedentro de tabelas são adequadas para uso em tabelas
• para regras horizontais na tabela são utilizadas linhas definidas no boldlinepacote
• para coluna com listas é definir um novo tipo de coluna I(veja MWE abaixo)

Editar:

• mais espaços verticais superiores nas células são obtidos usando o cellspacepacote e inferiores com configurações itemizena tabela
• removidos não são usados ​​fragmentos de código e definições de tipo de coluna corrigidas

Ao alterar seu \endheadto \\e adicionar os pacotes necessários (além de alterar o tipo de coluna para Xpara permitir que o tabularx "funcione"), esse erro desapareceu:
