I basically want to list attribute names and a attribute description in a table. The attributes belong to a certain category. The idea is to list all attributes in one table to avoid creating multiple tables for each category. At the moment I am simply subdividing the table by using midrules for each category. The result looks ok, but I wonder if there is a more beautiful way to do this (e.g. indenting the rows below each category).
\documentclass{article} \usepackage{booktabs} \begin{document} \begin{table}[h] \centering \begin{tabular}{ll} \toprule \textbf{Attribute} & \textbf{Description} \\ \midrule \multicolumn{2}{l}{{Category 1}} \\ \midrule A1 & D1 \\ A2 & D2 \\ \midrule \multicolumn{2}{l}{{Category 2}} \\ \midrule A3 & D3 \\ A4 & D4 \\ \bottomrule \end{tabular} \end{table} \end{document} 

\documentclass{...}and ending with\end{document}.
