smartdiagram tabular inside additions nodes

Question

I have the following diagram, created with tikz smartdiagram. As you can see, it's possible to add a tabular inside a normal block. But is it possible to add a tabular, similar the existing one, inside an additional node? If not, has someone an idea how to create a diagramm like that?

    }
    \smartdiagramconnect{->}{module2/additional-module1}        \smartdiagramconnect{->}{additional-module2/module2}
    \smartdiagramconnect{->}{additional-module3/module2}
\end{center}
\vspace{50mm}\par
\label{tab:gyroMeanOffsetCorrectionSchema}
\captionsetup{justification=centering}
\captionof{figure}{gyroMeanOffsetCorrection Schema}
\end{figure}

\end{document}

the error I get when I add a tabular to an additional node is: Use of \@xs@StrCut@@ doesn't match its definition. }

Answer 1

It works fine if you save the tabular in a box first. Making the code in the question a bit more minimal, for example, by removing some of the irrelevancies:

\documentclass[12pt,a4paper,twoside]{report}
\usepackage[utf8]{inputenc}
\usepackage[rgb]{xcolor}
\usepackage{tikz}
\usetikzlibrary{shadows}
\usetikzlibrary{mindmap,arrows}
\usepackage{smartdiagram}
\usesmartdiagramlibrary{additions}

\begin{document}
\definecolorseries{colours}{hsb}{grad}[hsb]{.575,1,1}{.987,-.234,0}
\resetcolorseries[12]{colours}
\smartdiagramset{%
  back arrow disabled=true,
  module minimum width=4cm,
  module minimum height=4cm,
  module x sep=5cm,
  text width=4cm,
  arrow style=<-,
  additions={
    additional item offset=1cm,
    additional item fill color=colours!!+!20,
    additional item border color=colours!!,
    additional arrow color=red,
    additional item width=4cm,
    additional item height=4cm,
    additional item text width=4cm,
    additional item bottom color=red!50,
    additional item shadow=drop shadow,
  }
}
\vspace*{50mm}
\newsavebox\outputbox
\sbox\outputbox{%
  \begin{tabular}{ll}
    Name & Unit\\ \hline
    accelerationX & g\\
    accelerationY & g\\
    accelerationZ & g\\
  \end{tabular}%
}
\smartdiagramadd[flow diagram:horizontal]{
  accelerometer
  \begin{tabular}{ll}
    Name & Unit\\ \hline
    accelerationX & g\\
    accelerationY & g\\
    accelerationZ & g\\
  \end{tabular}, Block
}{%
  below of module2/Output \usebox\outputbox,
  right of module2/gyroscope, above of module2/magnetometer
}
\smartdiagramconnect{->}{module2/additional-module1}        \smartdiagramconnect{->}{additional-module2/module2}
\smartdiagramconnect{->}{additional-module3/module2}

Off-topic:

• \label must come after \caption.

• \captionof is only required outside the relevant float kind. Within a figure environment, use \caption.

• Don't load packages you don't need; don't load redundant packages; don't load packages with different options. color can go. So can graphicx.

• Don't use the H specifier for figure. It is problematic and should better be avoided in 99% of cases.

• Use \centering within figure, table etc. and the center environment outside.

• halfparskip,headsepline are not valid options for this class.

• a4paper will give strange results when using a standard class without geometry.
