# Using dcolumn assignment with datatool

I seem unable to use columns defined with dcolumn with datatool. For example if my table is

table1.csv
events,100,10

\usepackage{dcolumn}
\usepackage{datatool}

\newcolumntype{d}{D{,}{\pm}{-1}}

\begin{table}[h]
\begin{tabular}{l d}%
{\bf Events} & {Number with Error} %
\DTLforeach*{table1}{%
\events=events,\num=num,\err=err}{%
\\
\events & \num , \err}%
\end{tabular}
\end{table}


If datatool was working with dcolumn, I'd expect a plus-or-minus sign between 100 and 10 when printed, but it returns a comma, "100 , 10"

Does anyone have any suggestions? I'd like to use datatool to automate a lot of the table making but I also really like the formatting afforded by dcolumn.

Your posted code wasn't complete, but when I filled in what I assumed were the missing bits, I do see a plus/minus sign?

\documentclass{article}
\usepackage{dcolumn}
\usepackage{datatool}

\newcolumntype{d}{D{,}{\pm}{-1}}

\begin{document}

\begin{table}[h]
\begin{tabular}{l d}%
{\bf Events} &\multicolumn{1}{c}{Number with Error}
\DTLforeach*{table1}{%
\events=events,\num=num,\err=err}{%
\\
\events & \num , \err}%
\end{tabular}
\end{table}

\end{document}

You're right, sorry about that. In fact I found the error when I looked for the difference in what I posted and what I was running over. My table1.csv actually looked like: events,$100$,$10$ (not: events,100,10). When I remove the \$s from the numbers in the csv file, it works fine. Thanks much! – Eric Jan 30 '12 at 13:43
