Question

All the contents of my table are located to the left of it. How do I center the contents of the columns and rows of this table?

• Table code.

\begin{table}[H]
    \centering
    \footnotesize
     \caption{Tabela de cadastro de clientes}
        \begin{tabular}{|p{7cm}|p{7cm}|}
        \hline
        \rowcolor{lightgray}\textbf{RF01. Cadastrar cliente} & \textbf{RNF01.01} \\
        \hline
        O sistema deve permitir o cadastro de novos clientes. &  Só é permitido funcionários realizarem essa função. \\
        \hline
    \end{tabular} \\ [0.5cm]

If you want to center the content of all rows and columns it seems to me enough you put the table among the tags:

\begin{center}
(... sua tabela aqui ...)
\end{center}

Already if you want to center the table itself:

\begin{table}[h!]
\centering
 (... sua tabela aqui ...)
\end{table}
