I write latex with IEEEtrans with TexLive version 2022.
I would like to have the header in the middle (red arrow) but the content on the left (purple arrow) as follows.
This is the code.
\documentclass[journal]{IEEEtran}
\begin{document}
\begin{table}[ht]
\renewcommand{\arraystretch}{1.25}
\label{tab:abbreviation}
\noindent\begin{tabularx}{\linewidth} { |
c |
>{\raggedright\arraybackslash}X |}
\hline
\textbf{Abbreviation} & \textbf{Explanation} \
\hline
ASAP & As soon as possible \
\hline
FIFO & First in first out \
\hline
TBA & To be announced\
\hline
\end{tabularx}
\end{table}
\end{document}
However, the result is as follows.
What needs to be revised from the code? Thank you.


\multicolumn{1}{c|}{\textbf{Explanation}}in the header. – campa Feb 08 '24 at 13:24
