None of my efforts to vertically center the second column are working.
First trying the tabular environment:
\documentclass[]{book}
\usepackage[paperheight=3.0in,paperwidth=4.0in,margin=0.65in,
heightrounded,showframe]{geometry}
\usepackage{tabularx, array}
\usepackage{multirow}
\usepackage{graphicx}
\def\myBioLoss{Biodiversity_Loss_CutTree.png}
\def\myPollution{Pollute_Smokestack.png}
\begin{document}
\begin{center}
\begin{tabular}{l m{2cm}}
\multicolumn{2}{l}{Ecological Ceiling} \
\includegraphics[width=.10\textwidth]{\myBioLoss} & Biodiversity \
\includegraphics[width=.10\textwidth]{\myPollution} & Pollution \
\end{tabular}
\end{center}
\end{document}
I've tried adjustbox from: Centering a column vertically with longtable and pictures in rows
which compiled but did not center.
I've tried tabularx and \def\tabularxcolumn#1{m{#1}} from Vertically center text in tabularx table, which compiled with the environment: \begin{tabularx}{\textwidth}{l m{2cm}} but did not center.
I've tried tabular* from Right-centered columns in tabular*, but this also compiled but did not center.
Lastly, this is for beamer: Problem with centering Images in a column (beamer) which does not help me.
Yes, I need the book class.
