Space between title and table

Question

The title of my table is very far from the table itself, I would like to know some way to decrease this spacing.

Code:

\begin{table}[!htb]
    \renewcommand{\arraystretch}{1.5}
    \caption{Cronograma de pesquisa}
    \label{cronograma}
    \begin{center}
        \begin{tabular}{c|c c c c c c c c c c c c}
            \hline 
            ATV & SET & OUT & NOV & DEZ & JAN & FEV & MAR & ABR & MAI & JUN & JUL & AGO \\
            \hline
            1 &  &  &  &  &  &  &  &  &  &  &  & \\             
            2 &  &  &  &  &  &  &  &  &  &  &  & \\
            3 &  &  &  &  &  &  &  &  &  &  &  & \\
            4 &  &  &  &  &  &  &  &  &  &  &  & \\
            5 &  &  &  &  &  &  &  &  &  &  &  & \\
            6 &  &  &  &  &  &  &  &  &  &  &  & \\
            7 &  &  &  &  &  &  &  &  &  &  &  & \\
            8 &  &  &  &  &  &  &  &  &  &  &  & \\
            \hline
        \end{tabular}
    \end{center}
\end{table}

Answer 1

The command \vspace serves to add or remove vertical spacing in Latex. If a positive number is used, it adds space. If a negative number is used, it removes.

In the case of your table, I removed 5mm between the caption and the table itself. See the code below and then the result I got.

\documentclass{article}

\begin{document}

\begin{table}[!htb]
    \renewcommand{\arraystretch}{1.5}
    \caption{Cronograma de pesquisa}
    \vspace{-5mm}
    \label{cronograma}
    \begin{center}
        \begin{tabular}{c|c c c c c c c c c c c c}
            \hline 
            ATV & SET & OUT & NOV & DEZ & JAN & FEV & MAR & ABR & MAI & JUN & JUL & AGO \\
            \hline
            1 &  &  &  &  &  &  &  &  &  &  &  & \\             
            2 &  &  &  &  &  &  &  &  &  &  &  & \\
            3 &  &  &  &  &  &  &  &  &  &  &  & \\
            4 &  &  &  &  &  &  &  &  &  &  &  & \\
            5 &  &  &  &  &  &  &  &  &  &  &  & \\
            6 &  &  &  &  &  &  &  &  &  &  &  & \\
            7 &  &  &  &  &  &  &  &  &  &  &  & \\
            8 &  &  &  &  &  &  &  &  &  &  &  & \\
            \hline
        \end{tabular}
    \end{center}
\end{table}
