PsPicture inside tabular

Question

When using PsPicture inside a tabular, aligning the picture to the top works fine using \raisebox{} as shown in tabular no. 1. I archieved additional space under the picture using \vspace. (Is there a better way to do it???)

Now, I would like to align a formula inside the left cell at the bottom while a PsPicture is located in the right cell. As shown in tabular no. 2, row no. 1, it works fine. But I intend to add a small space above the PsPicture using \vspace again. Unfortunately, the aligning of the text at the bottom works no more. How can I get the required space above the picture and align the formula to the bottom?

Answer 1

Two solutions:

• use booktabs and no vertical rules: the rules of booktabs have some vertical (adjustable) padding around them. The table xwill look more professional;
• use \raisebox{0pt}[\dimexpr\height+some length] to fool LaTeX and make it believe the figure height is slightly larger than its natural height.

Here is an example of both solutions:

\documentclass[a4paper,DIV=15,oneside,12pt]{scrartcl}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{booktabs} 
\usepackage{ragged2e}
\usepackage{graphicx}
\usepackage{array}
\usepackage{setspace}
\usepackage{pst-all}
\usepackage{auto-pst-pdf}

\newcolumntype{D}[1]{>{\Centering}p{#1}}

\begin{document}

\onehalfspacing

\begin{tabular}{b{0.47\textwidth}D{0.47\textwidth}}
\toprule
Formula &
\raisebox{0pt}[\dimexpr\height+5pt]{\begin{pspicture}
\psframe(0,0,)(6,5)
\end{pspicture}}\\\midrule
Formula &
\raisebox{0pt}[\dimexpr\height+5pt]{\begin{pspicture}
\psframe(0,0,)(6,5)
\end{pspicture}}\\\bottomrule
\end{tabular}

\vspace{\baselineskip}

\begin{tabular}{|b{0.47\textwidth}|D{0.47\textwidth}|}
\hline
Formula &
\raisebox{0pt}[\dimexpr\height+5pt]{\begin{pspicture}
\psframe(0,0,)(6,5)
\end{pspicture}}\\\hline
Formula &
\raisebox{0pt}[\dimexpr\height+5pt]{\begin{pspicture}
\psframe(0,0,)(6,5)
\end{pspicture}}\\\hline
\end{tabular}

\end{document} 

Answer 2

Use coordinates for pspicture! And if you need negative coordinates, then use the option shift for moving it up.

\documentclass[a4paper,DIV=15,oneside,12pt]{scrartcl}
\usepackage{booktabs} 
\usepackage{ragged2e}
\usepackage{array}
\usepackage{pst-all}    
\newcolumntype{D}[1]{>{\Centering}p{#1}}    
\begin{document}

\begin{tabular}{b{0.47\textwidth}D{0.47\textwidth}}\toprule
Formula & \begin{pspicture}(6,5.1) \psframe(6,5)\end{pspicture}\\\midrule
Formula & \begin{pspicture}(6,5.1) \psframe(6,5)\end{pspicture}\\\bottomrule
\end{tabular}

\bigskip
\begin{tabular}{|b{0.47\textwidth}|D{0.47\textwidth}|}\hline
Formula & \begin{pspicture}(6,5.2)\psframe(6,5)\end{pspicture}\\\hline
Formula & \begin{pspicture}(6,5.2)\psframe(6,5)\end{pspicture}\\\hline
\end{tabular}

\end{document}
