[Tex/LaTex] How to add vertical space after \hline without breaking vertical lines in a table

rulestables

I have seen similar questions on the matter (Question 1, Question 2) of adding vertical space and not breaking vertical lines, the solutions suggested are to add space after the \\ using \\[0.1cm] for example or changing the \arraystretch which I do not want to do. Using \\[0.1cm] allows me to add space just before a \hline but not after as well.

How can I add vertical space after a \hline without breaking vertical lines in a table?

Please find my MWE below:

\documentclass{scrreprt}
\usepackage{setspace}
\usepackage[left=2.5cm,right=2.5cm,top=3cm,bottom=3cm]{geometry}
\usepackage{array,tabularx}
\doublespacing

\begin{document}
\begin{table}[htb]
  \centering
  \onehalfspacing
  \caption{Table of info.}

    \begin{tabular}{c | c c}
 & C/S Analyser & O/N/H Analyser \\
 & EMIA 320 V2 & EMGA 830 \\[0.1cm]
   \hline
   \noalign{\vskip 0.1cm}
Sensitivity (ppm) & 0.1 & 0.001 \\
Furnace type & Induction & Impulse \\
Carrier gas & Pure O2 & Pure He \\[0.1cm]
   \hline
    \end{tabular}

  \doublespacing
  \label{tab:chem}
\end{table}
\end{document}

Best Answer

You can do that with the cellspace package: define a minimal vertical padding of rows, and prefix the relevant column specifier with the letter S (or C if you use siunitx):

\documentclass{scrreprt}
\usepackage{setspace}
\usepackage[left=2.5cm,right=2.5cm,top=3cm,bottom=3cm]{geometry}
\usepackage{array,tabularx}
\doublespacing
\usepackage{cellspace}
\setlength\cellspacetoplimit{5pt}
\setlength\cellspacebottomlimit{5pt}
\begin{document}

\begin{table}[htb]
  \centering
  \onehalfspacing
  \caption{Table of info.}
  \begin{tabular}{c | Sc c}
    \hline
                      & C/S Analyser & O/N/H Analyser \\
                      & EMIA 320 V2 & EMGA 830 \\
    \hline
    Sensitivity (ppm) & 0.1 & 0.001 \\
    Furnace type & Induction & Impulse \\
    Carrier gas & Pure O2 & Pure He \\
    \hline
  \end{tabular}

  \doublespacing
  \label{tab:chem}
\end{table}
\end{document}
