Capitalize the caption in IEEEeqnarraybox environment

Question

I have a problem with using \subcaption and IEEEeqnarraybox in IEEEtran class.

The caption should look like below along with using \subcaption(as it does without using \subcaption)

but it looks like below with using \subcaption

Following is MWE:

\documentclass[twoside]{IEEEtran}
\usepackage[utf8]{inputenc}
\usepackage{newunicodechar}
\usepackage{booktabs}
\usepackage{lipsum}
\usepackage{subcaption}

\begin{document}

\lipsum[2]

\begin{table}[!t]
    \centering
    \caption{This is a Caption. \label{mylabel}}
    \centering
    \begin{IEEEeqnarraybox}[
        \IEEEeqnarraystrutmode
        \IEEEeqnarraystrutsizeadd{3pt}
        {1pt}
        ]{c'c'c/v/c'c'c}
    a & b& c && d & e
        \\\hline
        1 & 3 & 3 && +1 & +1 \\
        3 & 5 & 4 && +1 & -1 \\
        2& 2& 3  && -1 & +1 \\
        4& 44& 24 && -1 & -1 \\
        4& 5 & 10 && -1 & +1 
    \end{IEEEeqnarraybox}
\end{table}

\lipsum[1-40]

\end{document}

Answer 1

Please note that the caption package regards the IEEEtran class as being not supported and gives a clear warning to refrain from using caption here...

However, it works with

\captionsetup[table]{name=TABLE,labelsep=newline,justification=centering,textfont=sc}

The \label has to be put outside.

\documentclass[twoside]{IEEEtran}
\usepackage[utf8]{inputenc}
\usepackage{newunicodechar}
\usepackage{booktabs}
\usepackage{lipsum}
\usepackage{subcaption}

\begin{document}

\lipsum[2]


\captionsetup[table]{name=TABLE,labelsep=newline,textfont=sc}



\begin{table}[!t]
    \centering
    \caption{This is a Caption.}
    \centering
    \begin{IEEEeqnarraybox}[
        \IEEEeqnarraystrutmode
        \IEEEeqnarraystrutsizeadd{3pt}
        {1pt}
        ]{c'c'c/v/c'c'c}
    a & b& c && d & e
        \\\hline
        1 & 3 & 3 && +1 & +1 \\
        3 & 5 & 4 && +1 & -1 \\
        2& 2& 3  && -1 & +1 \\
        4& 44& 24 && -1 & -1 \\
        4& 5 & 10 && -1 & +1 
    \end{IEEEeqnarraybox}
\end{table}

\lipsum[1-40]

\end{document}

Answer 2

The caption package is incompatible with IEEEtran.cls, as the warning

Package caption Warning: Unsupported document class (or package) detected,
(caption)                usage of the caption package is not recommended.
See the caption package documentation for explanation.

hints at. Copy editors at IEEE will be very annoyed by contributors trying to break the class.

If you need subfloats, you can do

\usepackage[caption=false]{subfig}

and use \subfloat instead of subfigure (syntax change is necessary).
