Formatting table border and text alignment in LaTeX table

Question

I have the following table in the .tex file:

\documentclass{article}
\usepackage{booktabs}
\begin{document}

\begin{table}[htbp]
  \centering
  \caption{Distribution of Number of Injured Non-Motorists by Injury Severity Level}
    \begin{tabular}{rcccccc}
    \toprule
    \textbf{Injury Severity } & \multicolumn{2}{c}{\textbf{Pedestrian}} & \multicolumn{2}{c}{\textbf{Bicyclist}} & \multicolumn{2}{c}{\textbf{All Non-Motorists}} \\
    \midrule
    Possible injury & 1700  & 67.70\% & 502   & 59.40\% & 2202  & 65.60\% \\
    Non-Incapacitating injury & 523   & 20.80\% & 259   & 30.70\% & 782   & 23.30\% \\
    Incapacitating injury & 250   & 10.00\% & 84    & 9.90\% & 334   & 9.90\% \\
    Fatal injury & 39    & 1.50\% & 0     & 0.00\% & 39    & 1.20\% \\
    \textbf{Total} & \textbf{2512} & \textbf{100.00\%} & \textbf{845} & \textbf{100.00\%} & \textbf{3357} & \textbf{100.00\%} \\
    \bottomrule
    \end{tabular}%
  \label{tab:dvar}%
\end{table}%

\end{document}

This gives me the following table: Table using Latex code

However, I want it in this specific format for my thesis:

Required formatting

Please note that the outer borders are 2 lines while the inner borders are single line. Also, the numbers are to be aligned along the decimal point.

Can anyone please help me out here?

You can use the tabu package which offers you ready to use features to control the attributes (thickness, color) of the rules; alignment at the decimal separator can be achieved using the dcolumn package:

\documentclass{article}
\usepackage{xcolor}
\usepackage{dcolumn}
\usepackage{tabu}

\newcolumntype{A}{D{.}{.}{2.3}}

\begin{document}

\begin{table}[htbp]
  \centering
  \caption{Distribution of Number of Injured Non-Motorists by Injury Severity Level}
    \extrarowsep=_3pt^3pt
     \begin{tabu}to\linewidth{|[2pt gray]r|c|A|c|A|c|A|[1.5pt gray]}
    \tabucline[1.5pt gray]-
    \bfseries Injury Severity  & \multicolumn{2}{c|}{\textbf{Pedestrian}} & \multicolumn{2}{c|}{\textbf{Bicyclist}} & \multicolumn{2}{c|[1.5pt gray]}{\textbf{All Non-Motorists}} \\
    \tabucline[1.5pt gray]-
    Possible injury & 1700  & 67.70\% & 502   & 59.40\% & 2202  & 65.60\% \\
    Non-Incapacitating injury & 523   & 20.80\% & 259   & 30.70\% & 782   & 23.30\% \\\hline
    Incapacitating injury & 250   & 10.00\% & 84    & 9.90\% & 334   & 9.90\% \\\hline
    Fatal injury & 39    & 1.50\% & 0     & 0.00\% & 39    & 1.20\% \\
    \tabucline[1.5pt gray]-
    \bfseries Total & \bfseries 2512 & \multicolumn{1}{c|}{\bfseries 100.00\%} & \bfseries 845 & \multicolumn{1}{c|}{\bfseries 100.00\%} & \bfseries 3357 & \multicolumn{1}{c|[1.5pt gray]}{\bfseries 100.00\%} \\
    \tabucline[1.5pt gray]-
    \end{tabu}%
 \label{tab:dvar}%
\end{table}%

\end{document}

enter image description here

Just for comparison purposes, the same table without the vertical rules and some of the horizontal ones:

\documentclass{article}
\usepackage{xcolor}
\usepackage{dcolumn}
\usepackage{tabu}

\newcolumntype{A}{D{.}{.}{2.3}}

\begin{document}

\begin{table}[htbp]
  \centering
  \caption{Distribution of Number of Injured Non-Motorists by Injury Severity Level}
    \extrarowsep=_3pt^3pt
     \begin{tabu}to\linewidth{rcAcAcA}
    \tabucline[1.5pt gray]-
    \bfseries Injury Severity  & \multicolumn{2}{c}{\textbf{Pedestrian}} & \multicolumn{2}{c}{\textbf{Bicyclist}} & \multicolumn{2}{c}{\textbf{All Non-Motorists}} \\
    \tabucline[1.5pt gray]-
    Possible injury & 1700  & 67.70\% & 502   & 59.40\% & 2202  & 65.60\% \\
    Non-Incapacitating injury & 523   & 20.80\% & 259   & 30.70\% & 782   & 23.30\% \\
    Incapacitating injury & 250   & 10.00\% & 84    & 9.90\% & 334   & 9.90\% \\
    Fatal injury & 39    & 1.50\% & 0     & 0.00\% & 39    & 1.20\% \\
    \tabucline[1.5pt gray]-
    \bfseries Total & \bfseries 2512 & \multicolumn{1}{c}{\bfseries 100.00\%} & \bfseries 845 & \multicolumn{1}{c}{\bfseries 100.00\%} & \bfseries 3357 & \multicolumn{1}{c}{\bfseries 100.00\%} \\
    \tabucline[1.5pt gray]-
    \end{tabu}%
 \label{tab:dvar}%
\end{table}%

\end{document}

In my opinion, this second version looks much better, but I understand the original requirement for the thesis.

Yo can use the solution from How can I reproduce this table with thick lines? to obtain the thick lines.

Code:

Hi @peter... I think the image is a bit fuzzy but I want double lined border, not thick lines. — sriramn, Oct 28 '12 at 02:46
Damm, other solutions already so no point in me providing the same thing.. But I think that you have gone from a good table, to a, well... not so good... Just my opinion... — Peter Grill, Oct 28 '12 at 02:55

hhline provides the means to achieve a double-line border, at the loss of eye-candy. Here's a start for your table:

enter image description here

\documentclass{article}
\usepackage{tabularx,hhline}% http://ctan.org/pkg/{tabularx,hhline}
\begin{document}

\begin{table}[htbp]
  \centering
  \caption{Distribution of Number of Injured Non-Motorists by Injury Severity Level}
  \begin{tabularx}{\linewidth}{||l*{6}{|r}||}
    \hhline{|t:=======:t|}
    \textbf{Injury Severity } & \multicolumn{2}{c|}{\textbf{Pedestrian}} & \multicolumn{2}{c|}{\textbf{Bicyclist}} & \multicolumn{2}{c||}{\textbf{All Non-Motorists}} \\
    \hhline{|:=|==|==|==:|}
    Possible injury & 1700  & 67.70\% & 502   & 59.40\% & 2202  & 65.60\% \\
    Non-Incapacitating injury & 523   & 20.80\% & 259   & 30.70\% & 782   & 23.30\% \\
    Incapacitating injury & 250   & 10.00\% & 84    & 9.90\% & 334   & 9.90\% \\
    Fatal injury & 39    & 1.50\% & 0     & 0.00\% & 39    & 1.20\% \\
    \hhline{||-------||}
    \textbf{Total} & \textbf{2512} & \textbf{100.00\%} & \textbf{845} & \textbf{100.00\%} & \textbf{3357} & \textbf{100.00\%} \\
    \hhline{|b:=======:b|}
  \end{tabularx}
  \label{tab:dvar}
\end{table}

\end{document}

See the hhline documentation for the format used increating double lines and their intersections. The following is taken directly from the documentation (p 2):

Centred decimal alignment is achievable using some boxing techniques (provided by \padfour, \padthree and \padtwo) and dcolumn's D-column specification:

enter image description here

\documentclass{article}
\usepackage{tabularx,dcolumn,hhline}% http://ctan.org/pkg/{tabularx,dcolumn,hhline}
\newcommand{\padfour}[1]{\setbox0=\hbox{0000}\makebox[\wd0][r]{#1}}%
\newcommand{\padthree}[1]{\setbox0=\hbox{000}\makebox[\wd0][r]{#1}}%
\newcommand{\padtwo}[1]{\setbox0=\hbox{00}\makebox[\wd0][r]{#1}}%
\begin{document}

\begin{table}[htbp]
  \centering
  \caption{Distribution of Number of Injured Non-Motorists by Injury Severity Level}
  \begin{tabularx}{\linewidth}{||l*{3}{|c|D{.}{.}{2.3}}||}
    \hhline{|t:=======:t|}
    \textbf{Injury Severity } & \multicolumn{2}{c|}{\textbf{Pedestrian}} & \multicolumn{2}{c|}{\textbf{Bicyclist}} & \multicolumn{2}{c||}{\textbf{All Non-Motorists}} \\
    \hhline{|:=|==|==|==:|}
    Possible injury           & \padfour{1700} & 67.70\% & \padthree{502} & 59.40\% & \padfour{2202} & 65.60\% \\
    Non-Incapacitating injury & \padfour {523} & 20.80\% & \padthree{259} & 30.70\% & \padfour {782} & 23.30\% \\
    Incapacitating injury     & \padfour {250} & 10.00\% & \padthree {84} &  9.90\% & \padfour {334} &  9.90\% \\
    Fatal injury              & \padfour  {39} &  1.50\% & \padthree  {0} &  0.00\% & \padfour  {39} &  1.20\% \\
    \hhline{||-------||}
    \textbf{Total} & \textbf{2512} & \multicolumn{1}{c|}{\bfseries 100.00\%} & \textbf{845} & \multicolumn{1}{c|}{\bfseries 100.00\%} & \textbf{3357} & \multicolumn{1}{c||}{\bfseries 100.00\%} \\
    \hhline{|b:=======:b|}
  \end{tabularx}
  \label{tab:dvar}

dcolumn does not enjoy the use of \textbf in the final row, so you have to use a \bfseries approach.

How did you achieve the decimal alignment? Excellent response.. But as you noted - it is a bit of a sore sight :( — sriramn, Oct 28 '12 at 03:01
@RazorXsr: A traditional r column specification. However, I've added some more alignment option by using boxes of fixed width. Gonzalo's answer with tabu is most likely the way to go. — Werner, Oct 28 '12 at 03:05
@GonzaloMedina: Right. dcolumn doesn't enjoy \textbf{<stuff>}, but is fine with \multicolumn{1}{c|}{\bfseries <stuff>} - thanks. I'm beginning to like tabu more and more... :) — Werner, Oct 28 '12 at 03:50
