[Tex/LaTex] Making a space between table headings

tables

I want to replicate the table in this image but without the second column:

enter image description here

However the problem is that I'm unable to find out how to make a horizontal space between each two columns (N=2, N=3 … etc). Also I'm not able to find out how to make a vertical space between the first row and the second row (N=2 and Avg. Pos … etc) because the text is too close to the upperline.

Here is my version and code:

\begin{table}[h]
    \begin{tabular}{@{}lrrrrrr@{}}
        \toprule
        & \multicolumn{2}{c}{N = 2}                                     & \multicolumn{2}{c}{N = 3}                                     & \multicolumn{2}{c}{N = 4}                                      \\  \cline{2-3} \cline{4-5} \cline{6-7} 
        Network Name       & \multicolumn{1}{c}{Avg. Pos.} & \multicolumn{1}{c}{Avg. Neg.} & \multicolumn{1}{c}{Avg. Pos.} & \multicolumn{1}{c}{Avg. Neg.} & \multicolumn{1}{c}{Avg. Pos.} & \multicolumn{1}{c}{Avg. Neg.} \\ \midrule
        X            & 4895                          & 135639                        & 77                            & 109622                        & 5                             & 16360                         \\ 
        Y               & 5426                          & 183685                        & 196                           & 204801                        & 9                             & 39977                         \\ 
        Z & 8959                          & 80669                         & 38                            & 109362                        & 4                             & 43329                         \\ \bottomrule
    \end{tabular}
\end{table}

For first, use \cmidrule(lr){2-3}, note (lr). For details, consult the booktabs manual. For second, use some strut like

\newcommand*{\mystrut}{\rule{0pt}{2.5ex}}

Change 2.5ex as you want.

\documentclass{article}
\usepackage{booktabs}
\newcommand*{\mystrut}{\rule{0pt}{2.5ex}}
\begin{document}
  \begin{table}[h]
    \begin{tabular}{@{}lrrrrrr@{}}
        \toprule
        & \multicolumn{2}{c}{N = 2}                                     & \multicolumn{2}{c}{N = 3}                                     & \multicolumn{2}{c}{N = 4}                                      \\  \cmidrule(lr){2-3} \cmidrule(lr){4-5} \cmidrule(lr){6-7}
     \mystrut   Network Name       & \multicolumn{1}{c}{Avg. Pos.} & \multicolumn{1}{c}{Avg. Neg.} & \multicolumn{1}{c}{Avg. Pos.} & \multicolumn{1}{c}{Avg. Neg.} & \multicolumn{1}{c}{Avg. Pos.} & \multicolumn{1}{c}{Avg. Neg.} \\ \midrule
        X            & 4895                          & 135639                        & 77                            & 109622                        & 5                             & 16360                         \\
        Y               & 5426                          & 183685                        & 196                           & 204801                        & 9                             & 39977                         \\
        Z & 8959                          & 80669                         & 38                            & 109362                        & 4                             & 43329                         \\ \bottomrule
    \end{tabular}
\end{table}
\end{document}

[Tex/LaTex] Table with gap between cmidrule’s (extra space between two columns)

The only way to break the horizontal rule would be to insert a separate column (as you suggest), or to marginally trim the \cmidrules using the optional (..) specification:

enter image description here

\documentclass{article}

\usepackage{booktabs}

\begin{document}

\begin{tabular}{l c c c c}
  \toprule
  & \multicolumn{2}{c}{Text1} & \multicolumn{2}{c}{Text2} \\
  \cmidrule{2-3} \cmidrule{4-5}
  & A & B & A & B \\
  \midrule
  Foo & 1 & 2 & 3 & 4 \\
  \bottomrule
\end{tabular}

\bigskip

\begin{tabular}{l c c c c}
  \toprule
  & \multicolumn{2}{c}{Text1} & \multicolumn{2}{c}{Text2} \\
  \cmidrule(lr){2-3} \cmidrule(lr){4-5}
  & A & B & A & B \\
  \midrule
  Foo & 1 & 2 & 3 & 4 \\
  \bottomrule
\end{tabular}

\bigskip

\begin{tabular}{l c c c c c}
  \toprule
  & \multicolumn{2}{c}{Text1} & & \multicolumn{2}{c}{Text2} \\
  \cmidrule{2-3} \cmidrule{5-6}
  & A & B & & A & B \\
  \midrule
  Foo & 1 & 2 & & 3 & 4 \\
  \bottomrule
\end{tabular}

\end{document}

Adding space in the column specification using

\begin{tabular}{l c c@{\hspace{1cm}} c c}

inserts 1cm between columns 3 and 4, but would require you to correct alignment when using \multicolumn without providing the gap.

I don't think inserting an empty column is that bad. You could actually control the width of the column to provide a finely-tuned spacing of the \cmidrule separation. Something like

\begin{tabular}{l c c c@{\hspace{1cm}} c c}

Would give a gap of exactly 1cm between columns 3 and (now) 5.

[Tex/LaTex] Giving spaces between rows in a (multicolumn) table

Of course, remove vertical lines. For spacing properly the headers, as others stated, use booktabs, no doubt. For the multirow cell "Min width" is better use a \parbox or a minipage sice there are only a column of single digits. Also it is better add some space to the caption, that without additional packages can be done tuning \belowcaptionskip.

On the other hand, make the table simple as possible. If all your data are percentages, you can show information in the headers of each column, but it is better if you simply use the caption for that.

With respect to the columns, may be is better add some spacing between columns 3 and 4 to distinguish the two groups of data. A simple way is add an empty column or play with the column separators (@{}).

Finally, in this example I prefer do not follow decimal alignment because the uneven decimal columns in this case do not help too munch to distinguish numbers above or below 1 (waiting opposing views in 3, 2 ...) :)

enter image description here

\documentclass[11pt, twocolumn]{article}
\usepackage{booktabs,multirow}
\setlength{\belowcaptionskip}{5pt} 

\begin{document}


\begin{table}[ht]
\caption{String (\%)} 
\centering 
\begin{tabular}{cccccc} %  
\toprule
\multirow{2}{*}{
\parbox[c]{.2\linewidth}{\centering Min width}}
  & \multicolumn{2}{c}{$fp_{c}$} &&
\multicolumn{2}{c}{$fp_{bf}$} \\ 
\cmidrule{2-3} \cmidrule{5-6}

 & {\centering theory} & {exp.} && {theory} & {exp.}  \\
\midrule
1 & 0.23  & 0.21  && 0.04               & 0.065 \\
2 & 0.085 & 0.087 && 0.0015             & 0.0020 \\
3 & 0.032 & 0.026 && $5.5\times10^{-4}$ & 0 \\
4 & 0.012 & 0.011 && $5.5\times10^{-4}$ & 0 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}
