I'm trying to put a table placed in the two columns of an article. This I can do. The problem is it won't stay in the middle of the text.
Here is my code,
\documentclass[11pt, twocolumn]{article}
\usepackage{lipsum}
\usepackage{float}
\usepackage{placeins}
\begin{document}
\section{Before you start}
\lipsum[1]
\begin{table*}[h!]
\begin{center}
\begin{tabular}{rccc|ccc}\\
\multicolumn{4}{c}{Model 1} &\multicolumn{3}{c}{Model2} \\
\hline
\hline
$SE(\%)$ & $60$ & $60$ & $60$ & $60$ & $60$ & $60$ \\
$SP(\%)$ & $70$ & $70$ & $70$& $70$ & $70$ & $70$ \\
$Gmean(\%)$ & $80$ & $80$ & $80$ & $80$ & $80$ & $80$
\label{tab:fO}
\end{tabular}
\end{center}
\end{table*}
\FloatBarrier
\lipsum[1]
\end{document}
and this is the result,


I would like the table to be in the middle of the text.
