Latex Table without vertical bars

Question

I am really under pressure, as I have to adjust a table to make it look like on the picture attached. Unfortunately, I am only used to create the standard table with vertical lines. Does anyone know, how to create something like that? Especially with the space in between the bars (hence abline does not seem to work).

Answer 1

The booktab package is what you need. It fixes some spacing problems, adds different rules depending on the position (\toprule,\bottomrule, etc). And it has a \cmidrule command, that is similar to \cline, but can be shortened on the left and/or right to give a column-like feeling.

To have centered and right aligned numbers, I use 4 groups of 3 columns. The first and third ones of each group have the same width and are used for centering and the second one holds the right aligned number. There are other possibilities, like the siunitx package, but the overall centering is slightly worse.

\documentclass{article}
\usepackage{booktabs}

\begin{document}
\begin{tabular}{*{4}{p{.8cm}rp{1cm}}}
  \multicolumn{3}{c}{(1)}&  \multicolumn{3}{c}{(2)}&  \multicolumn{3}{c}{(3)}&  \multicolumn{3}{c}{(4)}\\
  \multicolumn{3}{c}{IHS}&\multicolumn{3}{c}{Automotive}&\multicolumn{3}{c}{Transmission}&\multicolumn{3}{c}{Aggregates}\\
  \cmidrule(rl){1-3}\cmidrule(rl){4-6}\cmidrule(rl){7-9}\cmidrule(rl){10-12}
  &24&&&27&&&6&&&11&\\
  &127&&&5&&&10&&&19&\\
  \cmidrule(rl){1-3}\cmidrule(rl){4-6}\cmidrule(rl){7-9}\cmidrule(rl){10-12}
  &24&&&27&&&6&&&11&\\
  &127&&&5&&&10&&&19&\\
  \bottomrule
\end{tabular}
\end{document}

Answer 2

One last question regarding this topic: Do you know whether it is possible to vary the gap between the single columns? Meaning in case column 1 and 2 form the first group and column 3 and 4 the second one. How can I manipulate the code such that the gap between column 2 and 3 appears larger?

Thanks a lot!
