I am trying to place several images in a tabular arrangement using tabularx within a figure. The problem I have is that for some reason there is too much space between the last paragraph above the image and the image itself.

\begin{figure}[h]
%\setlength\tabcolsep{2pt}%
\begin{tabularx}{\textwidth}{@{}c*{3}{C}@{}}
\includegraphics[ width=0.3\linewidth, height=0.3\linewidth, keepaspectratio]{Imagen_a.png} &
\includegraphics[ width=0.3\linewidth, height=0.29\linewidth, keepaspectratio]{Imagen_b.png} &
\includegraphics[ width=0.3\linewidth, height=0.41\linewidth, keepaspectratio]{Imagen_c.png} &
\\
(a) & (b) & (c) & \\
\includegraphics[ width=0.3\linewidth, height=0.3\linewidth, keepaspectratio]{Imagen_d.png} &
\includegraphics[ width=0.3\linewidth, height=0.3\linewidth, keepaspectratio]{Imagen_e.png} &
\includegraphics[ width=0.3\linewidth, height=0.3\linewidth, keepaspectratio]{Imagen_e.png} &
\\
(d) & (e) & (f) & \\
\end{tabularx}
\caption{Spatial distribution of customers - centered depot. (a) 30C, (b) 22C, (c) 15C, (d) 20C, (e) 15C.1} \label{fig:spatial-distribution}
\end{figure}
Why is this space generated and how can I avoid it?
