[Tex/LaTex] How to increase row height while using booktabs

booktabsfractionsspacingtables

I'm making a table using booktabs. One of the columns contains a series of fractions.

\documentclass[12pt, letterpaper]{article}
    \usepackage{nag}
    \usepackage[margin=1.0in]{geometry}

    \usepackage{amsmath}

    \usepackage{booktabs}
    \usepackage[tableposition=top]{caption}

\begin{document}

\begin{table}[htbp]
\centering
\caption{Test}
\begin{tabular}{llll}
    \toprule
    A & B & C & D \\
    \midrule
    A: $\frac{6}{16}$ B: $\frac{5}{16}$ C: $\frac{3}{16}$ D: $\frac{2}{16}$ & 1.9375919592 & 1.88285606369 & 0.0547358955059 \\
    A: $\frac{6}{16}$ B: $\frac{5}{16}$ C: $\frac{4}{16}$ D: $\frac{1}{16}$ & 1.94014431443 & 1.80503653258 & 0.135107781856 \\
    A: $\frac{6}{16}$ B: $\frac{6}{16}$ C: $\frac{2}{16}$ D: $\frac{2}{16}$ & 1.87649654966 & 1.81127812446 & 0.0652184251977 \\
    A: $\frac{6}{16}$ B: $\frac{6}{16}$ C: $\frac{3}{16}$ D: $\frac{1}{16}$ & 1.87992559246 & 1.76409765557 & 0.115827936888 \\
    A: $\frac{7}{16}$ B: $\frac{3}{16}$ C: $\frac{3}{16}$ D: $\frac{3}{16}$ & 1.93245604561 & 1.88024081494 & 0.0522152306624 \\
    A: $\frac{7}{16}$ B: $\frac{4}{16}$ C: $\frac{3}{16}$ D: $\frac{2}{16}$ & 1.86806360636 & 1.84960175271 & 0.0184618536479 \\
    A: $\frac{7}{16}$ B: $\frac{4}{16}$ C: $\frac{4}{16}$ D: $\frac{1}{16}$ & 1.87194209421 & 1.7717822216 & 0.100159872612 \\
    A: $\frac{7}{16}$ B: $\frac{5}{16}$ C: $\frac{2}{16}$ D: $\frac{2}{16}$ & 1.81500630063 & 1.79617969195 & 0.0188266086843 \\
    A: $\frac{7}{16}$ B: $\frac{5}{16}$ C: $\frac{3}{16}$ D: $\frac{1}{16}$ & 1.81178637864 & 1.74899922306 & 0.0627871555774 \\
    \bottomrule
\end{tabular}
\end{table}

\end{document}

This is what is looks like:

table

The height of each row is just a tad too small — the fractions are uncomfortably squished. Is there any way I can increase the row height so the fractions fit more comfortably?

If possible, I'd also like to avoid making any changes to other tables that I might add to my document.

For single lines booktabs provides \addlinespace:

\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{table}\centering
\begin{tabular}{lrc} 
\toprule[2pt]
a & b & c \\ 
\cmidrule[1pt](rl){1-3}
d & e & f \\ 
j & k & l \\ 
\addlinespace[0.5em]
g & h & i \\ 
\bottomrule[2pt] 
\end{tabular}\caption{abcde}
\end{table}
\end{document}

[Tex/LaTex] Formatting table using booktabs

Since the whole outer cell, which contains \specialcell should be bold, \bfseries can be specified in the outer cell, right before \specialcell:

... & \bfseries\specialcell{...} & ...

This can also be put into a macro \specialcellbold, see the following example:

\documentclass{report}
\usepackage{booktabs}
\usepackage{array}
\newcommand*\rotbf[1]{\rotatebox{90}{\textbf{#1}}}
\newcommand{\specialcell}[2][c]{\begin{tabular}[#1]{@{}l@{}}#2\end{tabular}}
\newcommand{\specialcellbold}[2][c]{%
  \bfseries
  \begin{tabular}[#1]{@{}l@{}}#2\end{tabular}%
}

\begin{document}
\begin{table}[hbr]
\centering
\label{tbl:heatwheel_res}
\begin{tabular}{llll}
\toprule
\textbf{Parameter} &
\specialcellbold{Exhaust\\air} &
\specialcellbold{Exhaust and\\ outdoor air} &
\specialcellbold{Heat wheel\\(80~\%)} \\
\midrule
Heat recovery [\%] & 89,6 \% & 89,6 \% & 77,4 \% \\
Real heat recovery [\%] & 50,5 \% & 52,1 \% & - \\
Net energy need for VH and SH & 27,7 & 27,0 & 15,8 \\
\specialcell{Delivered energy for\\DHW, VH and SH} & 31,1 & 27,6 & 45,6 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}

The table formatted a little different:

\documentclass{report}
\usepackage{booktabs}
% \usepackage{array}% It can also be loaded explicitly, implicitly it is
%                     loaded by siunitx
\usepackage{siunitx}
% \sisetup{output-decimal-marker={,}}% OP now wants to have the default dot
\sisetup{detect-weight, mode=text}
\newcommand*\rotbf[1]{\rotatebox{90}{\textbf{#1}}}
\newcommand{\specialcell}[2][b]{\begin{tabular}[#1]{@{}c@{}}#2\end{tabular}}
\newcommand{\specialcellbold}[2][b]{%
  \bfseries
  \sisetup{text-rm=\bfseries}%
  \begin{tabular}[#1]{@{}c@{}}#2\end{tabular}%
}
\newcommand*{\leftspecialcell}[2][b]{%
  \begin{tabular}[#1]{@{}l@{}}#2\end{tabular}%
}

\begin{document}
\begin{table}[hbr]
\centering
\label{tbl:heatwheel_res}
\begin{tabular}{l*{3}{S[table-format=2.1]}}
\toprule
\textbf{Parameter} &
{\specialcellbold{Exhaust\\air}} &
{\specialcellbold{Exhaust and\\ outdoor air}} &
{\specialcellbold{Heat wheel\\(\SI{80}{\percent})}} \\
\midrule
Heat recovery [\si{\percent}] & 89,6 & 89,6 & 77,4 \\
Real heat recovery [\si{\percent}] & 50,5 & 52,1 & {---} \\
Net energy need for VH and SH & 27,7 & 27,0 & 15,8 \\
\leftspecialcell{Delivered energy for\\
  \quad DHW, VH and SH} & 31,1 & 27,6 & 45,6 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}

Remarks:

Bottom aligned header row.
Columns 2 to 4 are centered.
Use of package siunitx for aligning at the decimal marker and for setting the percent signs.
The lines after the first line in a left cell is indented. and the alignment follows the bottom line instead of vertical centering.
Use of em dash instead of the hyphen for the missing entry.
Redundant percent signs removed.
Changed the output decimal marker to the default dot (see comment of ROLF).
A little crude is \siunit{text-rm=\bfseries}. Option detect-weight did not work inside an S-column.

Update

I, Svend Tveskæg, found the code not very easy to read to I cleaned it up a bit (I hope it's okay):

\documentclass{report}

\usepackage{booktabs}
\usepackage{siunitx}

\sisetup{
%  output-decimal-marker = {,},
  detect-weight,
  mode = text
}
\newcommand*{\specialcell}[2][b]{%
  \begin{tabular}[#1]{@{}c@{}}#2\end{tabular}%
}
\newcommand*{\specialcellbold}[2][b]{%
  \bfseries
  \sisetup{text-rm = \bfseries}%
  \begin{tabular}[#1]{@{}c@{}}#2\end{tabular}%
}
\newcommand*{\leftspecialcell}[2][b]{%
  \begin{tabular}[#1]{@{}l@{}}#2\end{tabular}%
}

\begin{document}

\begin{table}[htbp]
 \centering
 \label{tbl:heatwheel-res}
  \begin{tabular}{l *{3}{S[table-format = 2.1]}}
   \toprule
    \textbf{Parameter}                                    &
    {\specialcellbold{Exhaust    \\ air}}                 &
    {\specialcellbold{Exhaust and\\ outdoor air}}         &
    {\specialcellbold{Heat wheel \\ (\SI{80}{\percent})}}       \\
   \midrule
    Heat recovery [\si{\percent}]         & 89,6 & 89,6 & 77,4  \\
    Real heat recovery [\si{\percent}]    & 50,5 & 52,1 & {---} \\
    Net energy need for VH and SH         & 27,7 & 27,0 & 15,8  \\
    \leftspecialcell{Delivered energy for                       \\
    \quad DHW, VH and SH}                 & 31,1 & 27,6 & 45,6  \\
   \bottomrule
  \end{tabular}
\end{table}
