Placing a figure inside a multirow table cell

A workaround I've just seen possible, without modifying the graphics, is this:

• Include package bigstrut
• Use the other parameters of multirow:
  • bigstruts: value 2.
  • fixup: value 2mm
• Add a call of \bigstrut for each row being spanned.
• Increasing \arraystretch to 3.

The code for the main tex file is this:

\documentclass[]{article}
\usepackage{amsmath}

\usepackage{graphicx}

\usepackage{booktabs}
\usepackage{multirow,bigstrut}
\usepackage{tabu}

\begin{document}
\begin{table}
\centering
\renewcommand{\arraystretch}{3}
\begin{tabu}{ccc}
    \toprule
    Sections & Axis & Imperfections\\
    \midrule
    \multirow{2}[2]{*}[2mm]{\includegraphics[width=3cm]{circular_hollow.pdf}} & $y-y$ & $\dfrac{L}{200}$ \bigstrut \\
                                                                              & $z-z$ & $\dfrac{L}{150}$ \bigstrut \\
    \bottomrule
\end{tabu}
\end{table}

\end{document}

For those wondering how to put images in tables in general, the salient point is the bracketed fixup after the {*} in \multirow:

\multirow{2}{*}[fixup]{\includegraphics[width=2in]{...}}

For example:

\multirow{2}{*}[0.5in]{\includegraphics[width=2in]{...}}

By adjusting the fixup you can avoid Latex's default behavior of putting the image way too low in the table.
