\midrule dashed and colored in booktabs -- two kinds of midrules in one booktab

Question

Is it possible to make two \midrules in one booktab? The first one should be colored, the second one colored and dashed, as it is shown in the picture. Before each entry is a horizontal space - how to include such space in my table?

Answer 1

You can use the tabu package instead:

\documentclass{beamer}          
\usepackage{tabu}

\begin{document}

\begin{frame}
\begin{table}
\tabulinesep =_4pt^4pt
\begin{tabu}to \textwidth{@{}cX[m]ccc@{}}
  \tabucline[1pt blue!40 off 0pt]{-}
  \multicolumn{2}{@{}l}{procesy} & Min & Max  &Dalkia\\
  \tabucline[0.7pt blue!40 off 0pt]{-}
  & Junior         & 1 700 & 2 800 & 3 200\\
  \tabucline[0.4pt blue!40 off 2pt]{-}
  & Senior         &  & ? &\\
  \tabucline[0.4pt blue!40 off 2pt]{-}
  & Specjalist     &  & ? &\\
  \tabucline[0.4pt blue!40 off 2pt]{-}
  & Team Leader    &  & ? &\\
  \tabucline[1pt blue!40 off 0pt]{-}
\end{tabu}
\caption{1. Wynagrodzenia: Procesy HR}
\label{tabela1}
\end{table}
\end{frame}

\end{document}

Answer 2

Here is an option that compares the tabu output of Gonzalo's answer with that of booktabs. It's workable in comparison with tabu, but it's not always pretty.

\documentclass{article}          
\usepackage{tabu}% http://ctan.org/pkg/tabu
\usepackage{xcolor}% http://ctan.org/pkg/xcolor
\usepackage{tabularx}% http://ctan.org/pkg/tabularx
\usepackage{booktabs}% http://ctan.org/pkg/booktabs
\makeatletter
\newcommand{\dashrule}[1][black]{%
  \color{#1}\rule[\dimexpr.5ex-.2pt]{4pt}{.4pt}\xleaders\hbox{\rule{4pt}{0pt}\rule[\dimexpr.5ex-.2pt]{4pt}{.4pt}}\hfill\kern0pt%
}
\newcommand{\rulecolor}[1]{%
  \def\CT@arc@{\color{#1}}%
}
\makeatother
\begin{document}

\begin{table}[t]
\tabulinesep =_4pt^4pt
\begin{tabu}to \textwidth{@{}cX[m]X[c]X[c]X[c]@{}}
  \tabucline[1pt blue!40 off 0pt]{-}
  \multicolumn{2}{@{}l}{procesy} & Min & Max  &Dalkia\\
  \tabucline[0.7pt blue!40 off 0pt]{-}
  & Junior         & 1 700 & 2 800 & 3 200\\
  \tabucline[0.4pt blue!40 off 2pt]{-}
  & Senior         &  & ? &\\
  \tabucline[0.4pt blue!40 off 2pt]{-}
  & Specjalist     &  & ? &\\
  \tabucline[0.4pt blue!40 off 2pt]{-}
  & Team Leader    &  & ? &\\
  \tabucline[1pt blue!40 off 0pt]{-}
\end{tabu}

\bigskip

\rulecolor{blue!40}
\begin{tabularx}{\linewidth}{X>{\centering}X>{\centering}X>{\centering\arraybackslash}X@{}}
  \toprule
  procesy & Min & Max & Delta \\
  \midrule
  Junior & 1\,700 & 2\,800 & 3\,200 \\[-\jot]
  \multicolumn{4}{@{}c@{}}{\makebox[\linewidth]{\dashrule[blue!40]}} \\[-\jot]
  Senior         &  & ? &\\
  \multicolumn{4}{@{}c@{}}{\makebox[\linewidth]{\dashrule[blue!40]}} \\[-\jot]
  Specjalist     &  & ? &\\
  \multicolumn{4}{@{}c@{}}{\makebox[\linewidth]{\dashrule[blue!40]}} \\[-\jot]
  Team Leader    &  & ? &\\
  \bottomrule
\end{tabularx}
\caption{1. Wynagrodzenia: Procesy HR}
\end{table}

\end{document}

The use of tabularx makes it convenient to specify the tabular width. Rule colour is specified using \rulecolor{<color>} and that of the dashed rule is done using \dashrule[<color>].

Answer 3

You can do that with NiceTabular} of nicematrix (≥ 6.6 of 2022-02-16).

\documentclass{beamer}          
\usepackage{nicematrix,tikz,booktabs}

\begin{document}

\begin{frame}
\begin{table}
\NiceMatrixOptions
  {
    custom-line = 
     {
       command = dashedmidrule ,
       tikz = { dashed , color = blue!40 } ,
       width = \pgflinewidth + \aboverulesep + \belowrulesep ,
     }
  }

\begin{NiceTabular}{@{}cX[m]ccc@{}}[rules/color=blue!40]
  \toprule
  \Block[l]{1-2}{procesy} && Min & Max  &Dalkia\\
  \midrule
  & Junior         & 1 700 & 2 800 & 3 200\\
  \dashedmidrule
  & Senior         &  & ? &\\
  \dashedmidrule
  & Specjalist     &  & ? &\\
  \dashedmidrule
  & Team Leader    &  & ? &\\
  \bottomrule
\end{NiceTabular}
\caption{1. Wynagrodzenia: Procesy HR}
\label{tabela1}
\end{table}
\end{frame}

\end{document}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).
