# Formatting of a \longtable containing a picture

I have a large table (spanning several pages) where also images are inserted (example is only part of the table). I've been looking for a solution how to vertically adjust the position of the images in the table but so far without success. Now the text is aligned with the bottom of the figure and that's not pretty. Would someone have a suggestion how to get the figures drop down by half their height in the column so that the text in the adjacent columns would be in the middle of the figure?

Another solution: use a m-column, as this aligns the cell contents vertically in the middle.

I added a newcolumntype "C", which takes the width of the column, you'll have to define. I replaced your 3rd "c"-column by my new "C"-column, making it 7.5cm wide.

You should also insert the images with \includegraphics[width=linewidth]{filename} commands. Please notice: a) I scaled the image with width=\linewidth as \linewidth automatically reflects the actual width of your column. If you change my (guessed) 7.5cm to 5 cm, \linewidth will be decreased accordingly. b) You do not need to add the file name extension ".jpg". PDFLaTeX will search for the existance of ".jpg" ".png" and ".pdf" for itself. (And if you happen to use classical LaTeX, it will search for ".ps", ".eps", ".ps.gz" and finally ".eps.gz".)

Here is the (no so minimal) example:

\documentclass[11pt,a4paper,twoside]{report}
\usepackage[utf8x]{inputenc}
\usepackage{ucs}
\usepackage{amsmath}
\usepackage{amsfonts}

\usepackage{latexsym}
\usepackage{caption}
\usepackage[table]{xcolor}
\usepackage{pgfplots}
\usepackage{booktabs}
\usepackage{pdflscape}
\usepackage{afterpage}
\usepackage{threeparttable}
\usepackage{longtable}

%% New column, define the width as #1, the m-column will align all
%% content in ther vertical middle, \centering will align it in the
%% horizontal middle.
\newcolumntype{C}[1]{%
>{\centering\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}

\begin{document}
\afterpage{
\clearpage
\thispagestyle{empty}
\begin{landscape}

And this is a cutout of the result.

• The [c] (more exactly [cc]) optional argument is the default. Dec 22 '16 at 11:32
• Yes, it is if you don't redefine \cellalign. Dec 22 '16 at 11:42

A simple \raisebox{-0.5\height}{\includegraphics{...}} usually does the trick.
