Fancy tables with TikZ

Today I wanted to create a table for a presentation and I remembered a suggestion made by Kjell Magne Fauske in comp.text.tex in August 2008, to use TikZ to create tables with rounded corners. I’ve investigated this idea further to achieve a colorful table layout in a shape that’s unusual for LaTeX. Here’s the result, displaying a ranking of Linux distributions produced by DistroWatch.com:
fancy tables with TikZ

The table has been put into a TikZ node, both at the top and at the bottom of the table I’ve used rectangles with rounded corners and some shading. A third rectangle is used to overlay parts of the other two rectangles.

The complete source code:

\documentclass{beamer}
\usetheme{default}
\usepackage{amsmath}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{colortbl}
\usepackage{tikz}
\usetikzlibrary{calc}
\pgfdeclarelayer{background}
\pgfdeclarelayer{foreground}
\pgfsetlayers{background,main,foreground}
\setbeamertemplate{background canvas}[vertical shading]%
[top=blue!1,bottom=blue!30]
\setbeamertemplate{navigation symbols}{}
\newcommand*\up{\textcolor{green}{%
\ensuremath{\blacktriangle}}}
\newcommand*\down{\textcolor{red}{%
\ensuremath{\blacktriangledown}}}
\newcommand*\const{\textcolor{darkgray}%
{\textbf{--}}}
