2. ¿No puede \flushleftel título de la tabla?
3. no puedo itemizeen la mesa

¡Ayúdame!

Aqui esta mi LATEX

Answer 1

El verticalcentrado se puede obtener utilizando el mtipo de columna que tiene el ancho de la columna como argumento.

Usé una tabularxtabla para proporcionar el resto del ancho disponible para la Descriptioncolumna, usando Xel tipo de columna.

Ambos ppermiten Xajustar líneas más largas, así como enumerar o detallar entornos.

Omití las líneas verticales a propósito porque no mejoran la legibilidad.

Answer 2

no puedo poner el texto en el centro del cuadro

Sugiero el tabularypaquete (o tabularxsugerido por Christian, dependiendo del tipo de columnas de la tabla quizás quieras uno u otro)

no se puede \flushleft el título de la tabla

\captionsetup{justification=raggedright, singlelinecheck=off}

no se puede detallar en la tabla

Usar una \parbox. Es esencialmente lo mismo que usar una pcolumna, pero también puedes usarla en otros tipos de columnas.

Un MWE reducido:

\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}
