table spanning only one column width in a multicol document

Question

I have a two-column document and what to inset a table. My problem is that the some of the columns in the table overlaps into the other side column. I have found a question which deals with generating a column spanning two columns. But I want to make the table fit within a column width. Any suggestions would be great? Does one have to resize the text or manually specify the column width?

Here is one option, where you could just decrease the inter-column spacing; Instead of a regular \tabcolsep, I've reduced that to 35% of \tabcolsep:

\documentclass[10pt]{scrartcl}
\usepackage[margin=25mm,paper=a4paper]{geometry}
\usepackage{booktabs}
\usepackage[colaction]{multicol}
\usepackage{setspace}
\usepackage{lipsum}
\title{Table formatting}
\author{The geniuses at SE}

\begin{document}
\maketitle
\doublespacing

\begin{multicols}{2}

\section{Introduction}      
\lipsum[1-1]

%\addvspace{\intextsep}% You may want to add this...

\noindent
\begin{minipage}{\columnwidth}
  \centering
  \captionaboveof{table}{Distribution of XXX}
  \setlength{\tabcolsep}{.35\tabcolsep}
  \begin{tabular}{ *{7}{c} }
    \toprule
    \textbf{Sex} &  \textbf{[0-1]} & \textbf{[1--5)} & \textbf{[5--10)} & \textbf{[10--25)} & \textbf{[25-50)} & \textbf{[50+]} \\
    \midrule
    M & 61\% & 28\% & 4\% & -\% & 6\% & x\% \\
    F & 60\% & 25\% & 5\% & 3\% & 7\% & x\% \\
    \bottomrule
  \end{tabular}
\end{minipage}

\addvspace{\intextsep}

\lipsum[1-2]

\end{multicols}

\end{document}

Since you included booktabs, I've used its rules.
