Improve this questionI would like to produce the following:
a b
xxxxx xxxxx
1 xxxxx xxxxx
xxxxx xxxxx
xxxxx xxxxx
2 xxxxx xxxxx
xxxxx xxxxx
Where the blocks of 'x's are images, and 'a', 'b', '1' and '2' are text.
Here are my two attempts so far:
\begin{figure}
\begin{center}
\begin{tabular}{ccc}
& a & b \\
1 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} &
\subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\
2 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} &
\subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\
\end{tabular}
\end{center}
\end{figure}
Which produces:
a b
xxxxx xxxxx
xxxxx xxxxx
1 xxxxx xxxxx
xxxxx xxxxx
xxxxx xxxxx
2 xxxxx xxxxx
And
\begin{figure}
\begin{center}
\begin{tabular}{m{1cm}m{6cm}m{6cm}}
& a & b \\
1 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} &
\subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\
2 & \subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} &
\subfloat[]{\includegraphics[width=0.47\textwidth]{im.png}} \\
\end{tabular}
\end{center}
\end{figure}
Which produces:
a b
xxxxx xxxxx
1 xxxxx xxxxx

xxxxx xxxxx
2 xxxxx xxxxx
xxxxx xxxxx
You can make a new column type, or simply add >{\centering\arraybackslash}
before m{6cm}
for the two image columns.
For example:
\newcolumntype{C}{>{\centering\arraybackslash} m{6cm} } %# New column type
\begin{tabular}{m{1cm}CC} %# Table with two of them
...
The >
directive lets you basically inject the contained code before each entry in that column. We need the \arraybackslash
to deal with incompatibility between the centering
environment and the tabular
environment. [More info can be found here.] 1
I use \dummyimage
, because I have no im.png
. Replace it with \includegraphics{im.png}
.
\font\dummyfont = cmr10 at 100pt
\def\dummyimage{{\vbox to 100pt{\vfil\hbox to 100pt{\hfil\dummyfont A\hfil}\vfil}}}
\hfil\vbox{
\halign{&\hfil\ $\vcenter{\hbox{#}}$\strut \ \hfil\cr
&a&b\cr
1&\dummyimage&\dummyimage\cr
2&\dummyimage&\dummyimage\cr
}}
