# longtabu: Fine tuning row separation

Consider this use of the longtabu environment from the tabu package:

\documentclass{memoir}
\usepackage{tabu}
\usepackage{longtable}

\begin{document}

\begin{longtabu}{lX}
\toprule
\textbf{Letter} & \textbf{Description}\\
\midrule

\bottomrule
\endlastfoot

Alpha & The first Greek letter.\\
Beta & The second Greek letter.\\
Gamma & The third Greek letter.
\end{longtabu}

\end{document}


This gives me the following table:

However, I would like to have a greater distance between the rows of the table. If I insert \tabulinesep=^2mm_2mm before the table, I get this:

Here the row spacing is fine, but the spacing also affects the distance between the rules and the text in the heading.

What I really want is headings and rules as in the first example, and row spacing as in the second example. It can be achieved by adding \addlinespace after each row in the first example, but this is tedious. Is there a simpler way to achieve what I want?

You could add a negative \addlinespace in your header. This is less tedious, I guess.

\endlastfoot
Alpha & The first Greek letter.\\
Beta & The second Greek letter.\\

\end{longtabu}
\tabulinesep=^2mm_2mm
\begin{longtabu}{lX}

• Negative \addlinespace! Of course. Much better. Thank you. – oz1cz Mar 12 '15 at 9:57
