Quer construir uma mesa assim

Question

Quero fazer uma tabela assim, mas ainda estou tendo alguns problemas:

1. não consigo colocar o texto no centro da caixa
2. não pode \flushlefto título da tabela
3. não posso itemizena mesa

Me ajude!

Aqui está meu LÁTEX

Answer 1

A verticalcentralização pode ser obtida usando o mtipo de coluna que tem como argumento a largura da coluna.

Usei uma tabularxtabela para fornecer o restante da largura disponível para a Descriptioncoluna, usando Xcolumntype.

Ambos ppermitem Xo agrupamento de linhas mais longas, bem como a enumeração ou a especificação de ambientes.

Omiti as linhas verticais propositalmente, pois elas não melhoram a legibilidade.

Answer 2

não consigo colocar o texto no centro da caixa

Eu sugiro o tabularypacote (ou tabularxsugerido pelo Christian, dependendo do tipo de colunas da tabela você pode querer uma ou outra)

não é possível \flushleft o título da tabela

\captionsetup{justification=raggedright, singlelinecheck=off}

não consigo discriminar na tabela

Use um \parbox. É essencialmente o mesmo que usar uma pcoluna, mas você também pode usá-lo em outros tipos de coluna.

Um MWE reduzido:

\documentclass[12pt,fleqn,a4paper]{book}
\usepackage{booktabs} % Required for nicer horizontal rules in tables
\usepackage{caption}
\captionsetup{justification=raggedright, singlelinecheck=off}
\usepackage{tabulary}
\begin{document}
\begin{table}
\caption{Signal Description Table Bus AXI}  
\begin{tabulary}{\linewidth}{llccLL}
\toprule
s\_axi\_lite\_aclk &
SLAVER & 
I & & AXI DMA AXI4-Lite Clock. Must be less than or equal to axi\_sg\_aclk for asynchronous mode. (C\_PRMRY\_IS\_ACLK\_ASYNC=1) \\
\midrule
\multicolumn{5}{c}{\bfseries AXI4 Lite Interface Signals}\\
\midrule
 s\_axi\_lite\_awvalid & 
 SLAVER & 
 O & 0 & 
 AXI4-Lite Write Address Channel Write Address Valid. 
%\parbox{\linewidth}{
\begin{itemize}
\item 1 = Write address is valid.
\item 0 = Write address is not valid.   
\end{itemize}
%}
\tabularnewline\bottomrule 
\end{tabulary}
\end{table}
