Graphics, Figures & Tables ⇒ Tightly fitting a frame around table with TikZ

[karlisrepsons]

The following example illustrates a couple of problems, the worst of which is the fact that TikZ is drawing the subsequent layer on the background layer with a space in between... Any idea how to control the distance between red and green lines?

make red closer to green and center..?

Got help in comp.text.tex; here I post a partial solution:

Code: Select all

\documentclass{article}

\usepackage[papersize={2.5cm, 2.5cm}]{geometry}
\usepackage{fontspec}
\usepackage{xcolor}
\usepackage{tabu}
\usepackage{tikz}

\geometry{
   showframe,
   inner=4mm,
   outer=4mm,
   top=4mm,
   bottom=4mm
}
\usetikzlibrary{
   backgrounds,
   calc
}

\tabulinesep=0pt
\tabcolsep=0pt
\tabulinestyle{1pt}

\newcommand{\textmode} {%
   \fontsize{24}{0}%
   \selectfont%
}

\begin{document}
\vspace*{\fill}
\noindent%
\begin{center}
   \taburulecolor{yellow}%
   \begin{tabu} spread 0pt
   {|X[-1, c, m]|}
      \tabucline-
      \begin{tikzpicture}[inner sep = 0pt, outer sep = 0pt]
         \node (tbl) {%
            \taburulecolor{green}%
            \begin{tabu} spread 0pt
            {|X[-1, c, m]|}
              \tabucline-
               \textmode%
               A
             \\
              \tabucline-
            \end{tabu}%
         };
         \begin{pgfonlayer}{background}
            \draw[line width=4pt, draw=red]
                 ($(tbl.north east) - (0,0)$)
                 rectangle ($(tbl.south west) + (0,0)$);
         \end{pgfonlayer}
      \end{tikzpicture}
     \\
      \tabucline-
   \end{tabu}
\end{center}
\vspace*{\fill}
\end{document}

Anyone can explain why the two

Code: Select all

\vspace*{\fill}

lines can't make the result be really in the middle? Note that documentclass got changed for "article", because with "minimal" it didn't work...

Here I'd like to share another example where I solved the original problem with excessive spacing. It looks like this:
