Is there a way to align tables in LaTeX?
I was writing a document with several tables in the same page, and often the edges don't match.
I would like to have tables aligned in both left and right edge.
\paragraph{Articoli}
\begin{large}
\begin{tabular}{ | l | l | l | p{3cm} |}
\hline

Answer 1

There are a number of ways to achieve this alignment:
Use a single tabular that would contain everything. This ensures the columns all use the same width:
\documentclass{article}
\begin{document}
\begin{tabular}{ l | l | l | l | p{3cm} |}
\cline{2-5}
& \textbf{Attributo} & \textbf{Tipo} & \textbf{Byte} & \textbf{Complessivo} \\
\cline{2-5}
& & & & 1500 occorrenze \\ \cline{2-5}
& Codice & Char(7) & 7 & 10,7 kB \\ \cline{2-5}
& Nome & Varchar (100) & 100 & 150 kB \\ \cline{2-5}
& Marca & Varchar (100) & 100 & 150 kB \\ \cline{2-5}
\textbf{Articoli} & Prezzo & Money & 8 & 12,2 kB \\ \cline{2-5}
& Disponibile & Integer & 4 & 6.2 kB \\ \cline{2-5}
& Soglia & Integer & 4 & 6.2 kB \\ \cline{2-5}
& Reparto & Char (4) & 4 & 6.2 kB \\ \cline{2-5}
& Totale & & & 321 kB \\ \cline{2-5}
& Dati + Block Header & & & 322 kB \\ \cline{2-5}
\multicolumn{1}{l}{}\\[\bigskipamount]
\cline{2-5}
& \textbf{Attributo} & \textbf{Tipo} & \textbf{Byte} & \textbf{Complessivo} \\
\cline{2-5}
& & & & 120 occorrenze \\ \cline{2-5}
& Codice & Char(4) & 4 & 0,5 kB \\ \cline{2-5}
\textbf{Reparti} & Nome & Varchar (100) & 100 & 12.1 kB \\ \cline{2-5}
& Sezione & Char(4) & 4 & 0.5 kB \\ \cline{2-5}
& Totale & & & 12.2 kB \\ \cline{2-5}
& Dati + Block Header & & & 12.3 kB \\ \cline{2-5}
\multicolumn{1}{l}{}\\[\bigskipamount]
\cline{2-5}
& \textbf{Attributo} & \textbf{Tipo} & \textbf{Byte} & \textbf{Complessivo} \\
\cline{2-5}
& & & & 10 occorrenze \\ \cline{2-5}
& Codice & Char(4) & 4 & 0,1 kB \\ \cline{2-5}
\raisebox{.5\normalbaselineskip}[0pt][0pt]{\textbf{Pagamenti}} &
Nome & Varchar (100) & 100 & 1 kB \\ \cline{2-5}
& Totale & & & 1.1 kB \\ \cline{2-5}
& Dati + Block Header & & & 1.2 kB \\ \cline{2-5}
\end{tabular}
\end{document}
Drawbacks here are the tables don't break across the page boundary (unless you use something like longtable or ltxtable).
Use boxes/overlapping/phantoms to adjust the appropriate entries so they align:
\documentclass{article}
\begin{document}
\leavevmode\rlap{\textbf{Articoli}}%
\phantom{\textbf{Pagamenti}}
\begin{tabular}{ | l | l | l | p{3cm} |}
\hline
\textbf{Attributo} & \textbf{Tipo} & \textbf{Byte} & \textbf{Complessivo} \\
\hline
& & & 1500 occorrenze \\ \hline
Codice & Char(7) & 7 & 10,7 kB \\ \hline
Nome & Varchar (100) & 100 & 150 kB \\ \hline
Marca & Varchar (100) & 100 & 150 kB \\ \hline
Prezzo & Money & 8 & 12,2 kB \\ \hline
Disponibile & Integer & 4 & 6.2 kB \\ \hline
Soglia & Integer & 4 & 6.2 kB \\ \hline
Reparto & Char (4) & 4 & 6.2 kB \\ \hline
Totale & & & 321 kB \\ \hline
Dati + Block Header & & & 322 kB \\ \hline
\end{tabular}
\bigskip
\leavevmode\rlap{\textbf{Reparti}}%
\phantom{\textbf{Pagamenti}}
\begin{tabular}{ | l | l | l | p{3cm} |}
\hline
\textbf{Attributo} & \textbf{Tipo} & \textbf{Byte} & \textbf{Complessivo} \\
\hline
& & & 120 occorrenze \\ \hline
Codice & Char(4) & 4 & 0,5 kB \\ \hline
Nome & Varchar (100) & 100 & 12.1 kB \\ \hline
Sezione & Char(4) & 4 & 0.5 kB \\ \hline
Totale & & & 12.2 kB \\ \hline
Dati + Block Header & & & 12.3 kB \\ \hline
\end{tabular}
\bigskip
\textbf{Pagamenti}
\begin{tabular}{ | l | l | l | p{3cm} |}
\hline
\textbf{Attributo} & \textbf{Tipo} & \textbf{Byte} & \textbf{Complessivo} \\
\hline
& & & 10 occorrenze \\ \hline
Codice & Char(4) & 4 & 0,1 kB \\ \hline

\end{tabular}

Note the use of % at the end of the overlapping line; this is to avoid a spurious space. See What is the use of percent signs (%) at the end of lines?
Here is another presentation using booktabs and siunitx, foregoing the excessive use of horizontal rules and no vertical rules at all:
\documentclass{article}
\usepackage{booktabs,siunitx,etoolbox}
\newcommand{\tipochar}[1]{Char~(#1)}
\newcommand{\tipovarchar}[1]{Varchar~(#1)}
\newcommand{\tipomoney}{Money}
\newcommand{\tipointeger}{Integer}
\sisetup{%
round-integer-to-decimal,
round-precision = 1,
round-mode = places
}%
\robustify\bfseries
\begin{document}
\begin{tabular}{
