I have a table that is too broad for a two-column page. Therefore, I have broken it into two parts:

\documentclass{eusflat2021}

\begin{table}[ht]
\begin{center}
\vspace{1ex}
\begin{tabular}{|c|c|c|c|c|c|} \hline
    {\bf GTW} & {\bf 10} & {\bf 15} & {\bf 20} & {\bf 25} & {\bf 30}  \\\hline
    Entropy &  & &&& \\
    IDF & 0.4301& 0.4552&0.4627&\textbf{0.4648}&0.4610 \\
    Normal & \textbf{0.4856} & 0.4802 &0.4769&0.4266&0.4181\\
    ProbIDF &0.3333&0.3628&0.3717&\textbf{0.3831}&0.3697\\
    LDA &\textbf{0.4668}&0.4587&0.4582&0.4482&0.4378 \\
    Norm-alt & \textbf{0.5598}&0.5066&0.5077&0.4685&0.4876\\
    \hline
\end{tabular}

\begin{tabular}{|c|c|c|c|c|} \hline
    {\bf GTW} & {\bf 35} & {\bf 40} & {\bf 45} & {\bf 50}  \\\hline
    Entropy &  & && \\
    IDF & 0.4523&0.4270&0.4349&0.4337 \\
    Normal &0.4176&0.3877&0.3724&0.3555\\
    ProbIDF &0.3773&0.3712&0.3608&0.3705\\
    LDA &0.4634&0.4518&0.4489&0.4481 \\
    Normal-alt &0.4784&0.4493&0.4515&0.4420\\
    \hline
\end{tabular}

enter image description here

However, by doing so, the top part is still too broad and the tables don’t align. Is there a way to make the top narrower and align the lines?

  • You should provide a code that we should compile (where can we find the class eusflat2021?). – F. Pantigny Mar 31 at 15:24
  • You can leave the twocolumn mode using \begin{table*} if this is an option. – NBur Mar 31 at 15:29

A solution is to transpose the tabular and reduce the space between columns. I also use booktabs to have a prettier table.

\usepackage{booktabs}
\usepackage{array}
\usepackage{multirow}
\usepackage{lipsum}

Use three table instead of only two.

I inserted them in the template they provide with Instructions for Authors.

\section{Figures}

All figures must be centered like Figure~\ref{figure1}.

You will be very lucky if all the tables end up in the same column or even on the same page!

For that possible contingency, this second code is better.

All tables must be centered and clear (See Table \ref{table}).

There's no way to get those tables to fit at the normal size.

You can either reduce the size, I found that 7.5pt fits, or use three tables.

Please note that, notwithstanding what the people at EUSFLAT think, the command \bf has been deprecated for 25 years.

I used \? (a command local to the table environment to ease input but, above all, its readability.
