Vertical alignment when using pictures in multirow

Question

I wrote the following table using multirow

Although as far as I know multirow should automatically do the vertical alignment, for me this happens only as long as I don't include pictures. What I am trying to do is the vertical centering of the content of the cells in the first column. Does anyone have any advice on how to solve this issue? The code is the following

\documentclass{article}
\usepackage{amsmath}
\usepackage{multirow,graphics,graphicx}
usepackage{booktabs}
\usepackage{array}

\begin{document}
\begin{table}[]
\centering
\caption{My caption}
\label{my-label}
\begin{tabular}{c|m{1.5cm}m{2cm}l} 
MR & GS & Typ & Sym \\ \hline
\multirow{4}*{ 1} & \includegraphics[width=1cm, height=1cm]{F1} & Tria&                        \\  
               & \includegraphics[width=1cm, height=1cm]{F1} & Obl           &            \\ 
                   & \includegraphics[width=1cm, height=1cm]{F1} & Sq            &            \\                    & \includegraphics[width=1cm,     height=1cm]{F1} & Rec   &            \\ \hline
\multirow{2}{*}{2} & \includegraphics[width=1cm, height=1cm]{F1} &     SqSnSq       &            \\ 
                   & \includegraphics[width=1cm, height=1cm]{F1} &     TrHex     &            \\ \hline
\multirow{2}{*}{3} & \includegraphics[width=1cm, height=1cm]{F1} &     TrKag        &            \\ 
                   & \includegraphics[width=1cm, height=1cm]{F1} &     RecShSq&            \\ 
\hline  
\end{tabular}
\end{table}

\end{document} 

Answer 1

I think it's easier not to use multirow and just use a nested tabular to the right, as tabular are vertically centred by default.

\documentclass{article}
\usepackage{amsmath}
\usepackage{multirow,graphics,graphicx}
\usepackage{booktabs}
\usepackage{array}

\begin{document}
\begin{table}
\centering
\caption{My caption}
\label{my-label}
\begin{tabular}{c|l} 
MR & 
\begin{tabular}[t]{@{}p{1cm}p{2cm}p{2cm}@{}}GS & Typ & Sym\end{tabular}
\\ \midrule
1 &
\begin{tabular}{@{}m{1cm}m{2cm}m{2cm}@{}}
 \includegraphics[width=1cm]{example-image} & Tria&                        \\  
 \includegraphics[width=1cm]{example-image} & Obl           &            \\ 
 \includegraphics[width=1cm]{example-image} & Sq            & \\
 \includegraphics[width=1cm]{example-image} & Rec   &  
\end{tabular}
    \\ \midrule
2 & 
\begin{tabular}{@{}m{1cm}m{2cm}m{2cm}@{}}
\includegraphics[width=1cm]{example-image} &     SqSnSq       &            \\ 
\includegraphics[width=1cm]{example-image} &     TrHex     & 
\end{tabular}
    \\ \midrule
3 &
\begin{tabular}{@{}m{1cm}m{2cm}m{2cm}@{}}
\includegraphics[width=1cm]{example-image} &     TrKag        &            \\ 
\includegraphics[width=1cm]{example-image} &     RecShSq&       
\end{tabular}
\\ \bottomrule 
\end{tabular}
\end{table}

\end{document}

I don't know whether this is the best solution, but you could use the vpos and vmove optional parameters of the multirow commands, as seen below

Roughly:

\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{multirow}
\usepackage{booktabs}
\usepackage{array}

\begin{document}
\begin{table}[]
\centering
\caption{My caption}
\label{my-label}
\begin{tabular}{c|m{1.5cm}m{2cm}l} 
MR & GS & Typ & Sym \\ \hline
\multirow[c]{4}{*}[-1cm]{1} & \includegraphics[width=1cm, height=1cm]{imma}& Tria&\\ 
               & \includegraphics[width=1cm, height=1cm]{imma} & Obl&    \\ 
                   & \includegraphics[width=1cm, height=1cm]{imma} & Sq & \\                    & \includegraphics[width=1cm,     height=1cm]{imma} & Rec   &            \\ \hline
\multirow[c]{2}{*}[-0.4cm]{2} & \includegraphics[width=1cm, height=1cm]{imma} &     SqSnSq       &            \\ 
                   & \includegraphics[width=1cm, height=1cm]{imma} &     TrHex     &            \\ \hline
\multirow[c]{2}{*}[-0.4cm]{3} & \includegraphics[width=1cm, height=1cm]{imma} &     TrKag        &            \\ 
                   & \includegraphics[width=1cm, height=1cm]{imma} &     RecShSq&            \\ 
\hline  
\end{tabular}
\end{table}

\end{document} 

Yielding:

Basically the syntax you would use is \multirow[vpos]{x}{*}[-y]{T} where:

• vpos is either b (bottom), c (centre), or t top

• x is the number of columns to span

• y is the vertical adjustment to insert. I put a minus before it because you have to move things down.

• T is the text of your multirow.

ALSO please mark that graphics is superseded by graphicx thus is no more needed

Moriambar’s solution is good, under the assumption that \multirow should be used.

Here's a different solution, under the assumption that empty cells denote repetition of the value.

\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage[export]{adjustbox}

\begin{document}

\begin{table}[htp]
\centering

\caption{My caption}
\label{my-label}

\begin{tabular}{ccll}
\toprule
MR & GS & Typ & Sym \\
\midrule
1 & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & Tria    &  \\
\addlinespace[2pt]
  & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & Obl     &  \\
\addlinespace[2pt]
  & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & Sq      &  \\
\addlinespace[2pt]
  & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & Rec     &  \\
\midrule
2 & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & SqSnSq  &  \\
\addlinespace[2pt]
  & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & TrHex   &  \\
\midrule
3 & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & TrKag   &  \\
\addlinespace[2pt]
  & \includegraphics[width=1cm,height=1cm,valign=c]{example-image} & RecShSq &  \\
\bottomrule
\end{tabular}

\end{table}
