Vertical lines only in certain columns

Question

For a table in my thesis I want to show a verti cal line only spanning 3 out of 5 columns.

My current table is:

\begin{table}[h]
\centering
\captionsetup{singlelinecheck=false}
\caption[Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen]{\textbf{Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen}}
\label{t:praeppcrcycler}
\centering
\begin{tabular}{lll}
\midrule
Temperatur & Zeit & \\
\midrule
98 \si{\degreeCelsius} & 3 min &  \\
& & \\

98 \si{\degreeCelsius} & 30 s &    \\
58 \si{\degreeCelsius} & 20-30 s & 30-35x \\
72 \si{\degreeCelsius} & 20-60 s &  \\

& & \\
72 \si{\degreeCelsius} & 3 min & \\
4 \si{\degreeCelsius} & $\infty$ & \\
\end{tabular}
\end{table}

which gives me this table

I do however want to add a vertical line spanning column 3, row 3 to 5 as in this picture

Any help is appreciated!

Answer 1

Here it is. I slightly simplified and improved your code:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{booktabs, caption, multirow, siunitx}

\begin{document}

\begin{table}[!htb]
  \captionsetup{singlelinecheck=false, justification=RaggedRight}
  \sisetup{range-phrase=--, range-units=single}
  \caption[Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen]{\textbf{Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen}}
  \label{t:praeppcrcycler}
  \centering
  \begin{tabular}{lll}
    \midrule
    Temperatur & Zeit & \\
    \midrule
    \SI {98}{\celsius} & \phantom{0}\SI{3}{min} & \\
                                     & & \\
    \SI{98}{\celsius} & \SI{30}{s} & \multicolumn{1}{|c}{} \\
    \SI{58}{\celsius} & \SIrange{20}{30}{s} & \multicolumn{1}|c}{30–35$\times$} \\
    \SI{72}{\celsius} & \SIrange{20}{60}{s} & \multicolumn{1}{|c}{} \\
                                     & & \\
    \SI{72}{\celsius}& \phantom{0}\SI{3}{min} & \\
    \phantom{0}\SI{4}{\celsius} & \phantom{0}$\infty$ & \\
    \midrule
  \end{tabular}
\end{table}

\end{document}

The following may be what you're looking for.

\documentclass[ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel,booktabs,siunitx}
\usepackage[skip=0.333\baselineskip,textfont=bf,
            singlelinecheck=false]{caption}
\begin{document}

\begin{table}[h]
\centering
\caption{Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen}
\label{t:praeppcrcycler}
\centering
\begin{tabular}{@{}lll@{}}
\midrule
Temperatur & Zeit & \\
\midrule
\SI{98}{\degreeCelsius} & 3\,min &  \\[2ex]
\SI{98}{\degreeCelsius} & 30\,s  &  
  \smash{\begin{tabular}[t]{|l@{}} 
            \\ 30--35$\times$ \\ \\
         \end{tabular}} \\
\SI{58}{\degreeCelsius} & 20--30\,s & \\
\SI{72}{\degreeCelsius} & 20--60\,s & \\[2ex]
\SI{72}{\degreeCelsius} & 3\,min    & \\
\SI{4}{\degreeCelsius}  & $\infty$  & \\
\bottomrule
\end{tabular}
\end{table}

\end{document}

Answer 3

Here is a solution with {NiceTabular} of nicematrix. That environment is similar to the classical environment {tabular} (of array) but creates PGF/Tikz nodes under the row, columns and cells. So it's possible to use Tikz to draw whatever rule you want after the main array by putting an instruction in the \CodeAfter (\tikz \draw (4-|3) -- (7-|3) ;).

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{ragged2e}
\usepackage{booktabs, caption, siunitx}
\usepackage{nicematrix}
\usepackage{tikz}


\begin{document}

\begin{table}[!htb]
  \captionsetup{singlelinecheck=false, justification=RaggedRight}
  \sisetup{range-phrase=--, range-units=single}
  \caption[Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen]{\textbf{Temperatur-Zyklus-Konditionen für präperative PCR-Reaktionen}}
  \label{t:praeppcrcycler}
  \centering
  \begin{NiceTabular}{lll}
    \midrule
    Temperatur & Zeit & \\
    \midrule
    \qty{98}{\celsius} & \phantom{0}\qty{3}{min} \\
                                     & & \\
    \qty{98}{\celsius} & \qty{30}{s} \\
    \qty{58}{\celsius} & \qtyrange{20}{30}{s} & 30–35$\times$ \\
    \qty{72}{\celsius} & \qtyrange{20}{60}{s} \\
                                     & & \\
    \qty{72}{\celsius}& \phantom{0}\qty{3}{min} \\
    \phantom{0}\qty{4}{\celsius} & \phantom{0}$\infty$ \\
    \midrule
  \CodeAfter \tikz \draw (4-|3) -- (7-|3) ;
  \end{NiceTabular}
\end{table}
