How to sort tabularx enteries in Latex? - sorting

Question

I have a tabularx in my file like this:
\begin{tabularx}{\linewidth}{c p{0.5cm} Y}
RFID & & Radio Frequency ID\cr
WSN & & Wireless Sensor Network\cr
IoT & & Internet of Things\cr
SN & & Sensor Network\cr
IEEE & & Institute of Electrical and Electronics Engineers
\end{tabularx}
I would like to know if there is any command that sorts the output of the tabularx in pdf, alphabetically, to get an output like:
List of Acronyms:
IEEE Institute of Electrical and Electronics Engineers
IoT Internet of Things
RFID Radio Frequency ID
SN Sensor Network
WSN Wireless Sensor Network

Answer 1

Instead if reinventing the wheel, I suggest to use one of the existing package to create lists of acronyms. One example:
\documentclass{book}
\usepackage[]{glossaries}
\makeglossaries
\newacronym{RFID}{RFID}{Radio Frequency ID}
\newacronym{WSN}{WSN}{Wireless Sensor Network}
\newacronym{IoT}{IoT}{Internet of Things}
\newacronym{SN}{SN}{Sensor Network}
\newacronym{IEEE}{IEEE}{Institute of Electrical and Electronics Engineers}
\begin{document}
\glsaddall
\printglossary[title={List of Acronyms},nonumberlist]
\end{document}
(to be compiled with pdflatex filename ; makeglossaries filename ; pdflatex filename)
