Tabular, make a column or a row emphasized

Question

I want to create a table and to make all cells of a column emphasized. Is there a simple way to do it, or do I have to emphasize every single cell?

Answer 1

>{..} defines what to do before the cell

\documentclass{article}
\usepackage{array}

\begin{document}

\begin{tabular}{c >{\em}c c}
foo & bar & baz
\end{tabular}

\end{document}
