# Caption spacing - table vs longtable

if I use both table and longtable in one document, the spacing between the caption and the table (the empty space after the caption) is different for table and longtable.

I would prefer minimal (and indeed identical) spacing after the caption in both cases. Thank you.

Example:

\documentclass[12pt]{article}
\usepackage{longtable, booktabs, graphicx}
\begin{document}

\begin{table}
\caption{This is the first caption}
\begin{center}
\resizebox{1\textwidth}{!}{
\begin{tabular}{@{}llllll@{}}
\toprule
\textbf{Name} & \textbf{Description} & \textbf{Unit} & \textbf{Data source} & \textbf{Time frame} & \textbf{Frequency} \\
\midrule
Name & Description & Unit & Data source & Time frame & Frequency \\
\bottomrule
\end{tabular}}
\end{center}
\end{table}

\begin{center}
\begin{longtable}{@{}p{2cm}p{1.5cm}p{3.6cm}p{1.2cm}p{1.5cm}p{1.5cm}@{}}
\caption{This is the second caption} \\
\toprule
\textbf{Author(s)} & \textbf{Area} & \textbf{Estimated relationship} & \textbf{Time frame}  & \textbf{Scope}  & \textbf{type} \\
\midrule
\multicolumn{6}{c}{\tablename\ \thetable\ -- \textit{Continued from previous page}} \\
\toprule
\textbf{Author(s)} & \textbf{Area} & \textbf{Estimated relationship} & \textbf{Time frame}  & \textbf{Scope}  & \textbf{ type} \\
\midrule
\midrule
\multicolumn{6}{r}{\textit{Continued on next page}} \\
\endfoot
\bottomrule
\endlastfoot
name & area & relationship & time & scope &  type \\
\end{longtable}
\end{center}
\end{document}

• \caption offered by article is designed to be typeset below the table (and has \abovecaptionskip between table and caption) while \caption offered by the longtable is designed to be typeset above the table (and has \baselikeskip between caption and table).

Load the caption package:

\documentclass[12pt]{article}
\usepackage{longtable, booktabs, graphicx, caption}
\captionsetup[table]{position=above}
\begin{document}

\begin{table}
\caption{This is the first caption}
\centering
\begin{tabular}{@{}llllll@{}}
\toprule
\textbf{Name} & \textbf{Description} & \textbf{Unit} & \textbf{Data source} & \textbf{Time frame} & \textbf{Frequency} \\
\midrule
Name & Description & Unit & Data source & Time frame & Frequency \\
\bottomrule
\end{tabular}
\end{table}

\begin{longtable}{@{}p{2cm}p{1.5cm}p{3.6cm}p{1.2cm}p{1.5cm}p{1.5cm}@{}}
\caption{This is the second caption} \\
\toprule
\textbf{Author(s)} & \textbf{Area} & \textbf{Estimated relationship} & \textbf{Time frame}  & \textbf{Scope}  & \textbf{type} \\
\midrule
\multicolumn{6}{c}{\tablename\ \thetable\ -- \textit{Continued from previous page}} \\
\toprule
\textbf{Author(s)} & \textbf{Area} & \textbf{Estimated relationship} & \textbf{Time frame}  & \textbf{Scope}  & \textbf{ type} \\
\midrule
\midrule
\multicolumn{6}{r}{\textit{Continued on next page}} \\
\endfoot
\bottomrule
\endlastfoot
name & area & relationship & time & scope &  type \\
\end{longtable}
\end{document}

1. Don't use the center environment inside table, but \centering
2. Don't use the center environment around longtable: the table will appear centered by default
3. Use \resizebox only as a last resort
4. Narrow p columns may be better handled if you add \raggedright, which you can do with the array package:

>{\raggedright\arraybackslash}p{3.6cm}


would be a good declaration for your third longtable column (add \usepackage{array} to your preamble.
