Table title in uppercase ieeetran class

Question

I'm using the \documentclass[journal]{IEEEtran} and the table title appears in lower case letters as: (Table I.) But, it is supossed that whitin this class the table title should go in uppercase, I'm just wondering what my problem is about.

here is a basic example:

\documentclass[journal]{IEEEtran}
\usepackage{cite}
\usepackage[cmex10]{amsmath}
\usepackage{url}
\usepackage[english]{babel}
\usepackage[utf8x]{inputenc}
\usepackage{graphicx}

\begin{document}

\begin{table}[!h]
\renewcommand{\arraystretch}{1.3}
\caption{Comparison}
\label{tab:1}
\centering
\begin{tabular}{*7c}
\hline
{} & \begin{tabular}[c]{@{}c@{}}Medium \\Reflectivity \% \end{tabular}& \multicolumn{3}{c}{\begin{tabular}[c]{@{}c@{}}Sub-bands' \\FWHM [pm]\end{tabular}} & \multicolumn{2}{c}{\begin{tabular}[c]{@{}c@{}}Sub-bands' \\Distance [pm]\end{tabular}}\\
\hline
Design S1 & 30 & 40 & 40 & 40 & 100 & 300 \\
S1 & 31.5 & 40.8 & 42.8 & 37.76 & 104 & 294 \\
Design S2 & 30 & 40 & 40 & 40 & 200 & 500 \\
S2 & 30.7 & 40.3 & 39.8 & 39.3 & 194 & 490 \\
\hline
\end{tabular}
\end{table}

\end{document}

Answer 1

While the class IEEEtran defines

\def\tablename{TABLE}

the package babel (rather, the language-specific file english.ldf) re-defines it back to

\def\tablename{Table}

Adding (thanks to egreg for the suggestion)

\addto\captionsenglish{\renewcommand*{\tablename}{TABLE}}

in the preamble after \usepackage{babel} should fix it.
