Graphics, Figures & Tables ⇒ A better table ?

[Cham]

I'm doing my first "standard" table, and I'm wondering about the quality output. How can I improve it ?

Here's a compilable sample :

Code: Select all

\documentclass[12pt,letterpaper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\usepackage{tensor}

\begin{document}

\begin{tabular}{|c|l|c|c|c|c|}
	\hline
	\multicolumn{6}{|c|}{\bf Title (white on black ?)} \\
	\hline\hline
	Model & & $\tensor{\Omega}{_{\text\it mat}}$ & $\tensor{\Omega}{_{\text\it rad}}$ & $\tensor{\Omega}{_{\Lambda}}$ & $k$ \\
	\hline
	\hline
	1 & A description & 0 & 0 & 0 & -1 \\
	\hline
	2 & Another small text & 1 & 0 & 0 & 0 \\
	\hline
	3 & Small text & 4 & 0 & 0 & 1 \\
	\hline
\end{tabular}

\end{document}

There's a preview below.

I would like to have its title in white on a black background (I already have tuned ON the xcolor package), and the column's width should be the same for the last four columns. How ?

Also, how can I make the horizontal lines (\hline) medium gray ?

[Cham]

I just discovered the colortbl package. But I'm wondering if there are other simple ways to do this.

This table is now pretty nice ! (compilable example)

Code: Select all

\documentclass[12pt,letterpaper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\usepackage{tensor}
\usepackage{xcolor}
\usepackage{colortbl}

\begin{document}

\begin{table}[H]
	\centering
\begin{tabular}{|c|l|c|c|c|c|}
	\hline
	\multicolumn{6}{|>{\columncolor[gray]{0.0} \color{white}} c|}{\bf A white on black title} \\
	\hline
	\rowcolor[gray]{0.9} Curve & & $\tensor{\Omega}{_{\text\it mat}}$ & $\tensor{\Omega}{_{\text\it rad}}$ & $\tensor{\Omega}{_{\Lambda}}$ & $k$ \\
	\hline
	\hline
	1 & Univers vide & 0 & 0 & 0 & $-1$ \\
	%\hline
	\rowcolor[gray]{0.96} 2 & Univers de poussières & 1 & 0 & 0 & $0$ \\
	%\hline
	3 & Univers clos & 4 & 0 & 0 & $1$ \\
	%\hline
	\rowcolor[gray]{0.96} 4 & Univers de radiation & 0 & 1 & 0 & $0$ \\
	%\hline
	5 & Univers de deSitter & 0 & 0 & 1 & $0$ \\
	%\hline
	\rowcolor[gray]{0.96} 6 & $\Lambda$CDM & 0.3 & 0 & 0.7 & $0$ \\
	\hline
\end{tabular}
	\caption{A caption.}
\end{table}

\end{document}

However, how can I tell LaTeX to give the last four columns the same width ?

Hi Cham,

However, how can I tell LaTeX to give the last four columns the same width?

you could use p columns with a fixed width. If you also load the array package, this would work well:

Code: Select all

\begin{tabular}{|c|l|*4{>{\centering\arraybackslash}p{1cm}|}}

Do you expect the table to be read column for column, from top to bottom? I guess I would read such a table from left to right. In this case, vertical lines blocking the way between cells would not be so good.

you could use p columns with a fixed width. If you also load the array package, this would work well:

Works very well. Thanks Stefan.

About the column separations, I'm not sure yet. Yes, the table is to be read from left to right. You suggest to remove the vertical lines ?

Maybe alternate gray cells ?

EDIT : Now what about gray vertical lines ? How can I do that ?

[cgnieder]

This might be a matter of taste, but I'd prefer as few horizontal lines as possible and no vertical lines and colors at all:

Code: Select all

\documentclass[12pt,letterpaper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath,tensor,booktabs,array}

\begin{document}

\begin{tabular}{cl*4{>{\centering\arraybackslash$}p{1cm}<{$}}}\toprule
\multicolumn{6}{c}{\bfseries Title (white on black ?)} \\ \midrule
Model & & \tensor{\Omega}{_{\text{\itshape mat}}} & \tensor{\Omega}{_{\text{\itshape rad}}} & \tensor{\Omega}{_{\Lambda}} & k \\
    1 & A description      & 0 & 0 & 0 & -1 \\
    2 & Another small text & 1 & 0 & 0 &  0 \\
    3 & Small text         & 4 & 0 & 0 &  1 \\
\bottomrule
\end{tabular}

Hmm, I think this table is too simple.

How can I improve this one ? I'm not sure about the gray vertical lines.

Very nice! Perhaps some additional @{} for removing space on the left and on the right, and if you need separation of subtitles, partial mid lines, with \cmidrule of booktabs.

Code: Select all

\begin{tabular}{@{}cl*4{>{\centering\arraybackslash$}p{1cm}<{$}}@{}}\toprule
  \multicolumn{6}{c}{\bfseries Title (white on black ?)} \\ \midrule
  Model & & \tensor{\Omega}{_{\text{\itshape mat}}} & \tensor{\Omega}{_{\text{\itshape rad}}} & \tensor{\Omega}{_{\Lambda}} & k \\
  \cmidrule(r){1-1}\cmidrule(lr){3-3}\cmidrule(lr){4-4}\cmidrule(lr){5-5}\cmidrule(l){6-6}
  1 & A description      & 0 & 0 & 0 & -1 \\
  2 & Another small text & 1 & 0 & 0 &  0 \\
  3 & Small text         & 4 & 0 & 0 &  1 \\
  \bottomrule
\end{tabular}

Funny, the aesthetical choice may be much harder than what I though.

I think the first table from this code may be a good one. However, how about alternate gray/white columns, instead of gray/white lines ?

Hmm, what about this version ?

table4.jpg (35.57 KiB) Viewed 7047 times

I'm not sure about the title bar, however. It's a bit too close to the second line. Any suggestion ?

[Cham]

I'm getting closer ! It's better without the heavy title bar, especially since there's already a caption below the table.

I'm not sure about the double rulers yet. Maybe I should add an extra vertical space below the first line...
