I'm writing a paper to submit to Statistics and computing, I use the svjour3 class and the twocolumn environment. I want to set a table between the text occupying two columns and I am not getting, does anyone know how to proceed? Here is an example code:
\documentclass[twocolumn]{svjour3}
\usepackage{lipsum,array}
\begin{document}
\title{foo}
\author{I}
\maketitle
\lipsum[1-10]
\begin{table*}
\centering
\caption{Empirical mean of the maximum likelihood}

I want, like the example below:


cute, however it also change a text flow. see @Bernard answer on https://tex.stackexchange.com/questions/368080/ – Zarko Jul 22 '18 at 15:10tableenvironment. You simply have to use thetabularenvironment, and\captionof{table}{mycaption}\label{some label}– Bernard Jul 22 '18 at 15:38
