Background color for complete table

Question

I would like to have an entire table (including the caption) with a background color. I already found solution for cells and rows (which also did not work perfectly), but not for the whole table.

Can I build an whole environment around it? If yes, how?

Thank you very much in advance

Answer 1

You can use simply \colorbox{your color}{your table}

MWE:

\documentclass{article}
\usepackage{booktabs,xcolor}
\begin{document}
\begin{table}
\caption{Foo}\centering 
\colorbox{green!20}{\begin{tabular}{cc}
foo & baz\\
\midrule
11 & 12 \\
13 & 14 \\
\end{tabular}}
\end{table}
\end{document}

It could look better with some settings before of the table (but inside the float if you want limit the setting to this table only). For instance:

\setlength\fboxsep{1ex}
\setlength\belowcaptionskip{1ex}
\setlength\tabcolsep{1ex}

Answer 2

The following MWE based on tcolorbox might serve as a starting point:

\documentclass{article}
\usepackage[most]{tcolorbox}
\usepackage{booktabs}

\newtcolorbox[blend into=tables]{mytable}[2][]{float=htb, 
                                               halign=center,  
                                               title={#2}, 
                                               every float=\centering, 
                                               sharp corners,
                                               coltitle=black,
                                               colback=yellow,
                                               colbacktitle=yellow,
                                               boxrule=0pt,
                                               frame hidden,
                                               #1}

\begin{document}

\begin{mytable}[float=t, label=mykey]{This is a floating box}
\begin{tabular}{cc}
\toprule
column header 1 & column header 2\\
\midrule
1 & 2 \\
3 & 4 \\
\bottomrule
\end{tabular}
\end{mytable}

\end{document}
