Na verdade, gostaria de escrever o conteúdo das duas últimas colunas no meio das duas linhas da primeira coluna. Aqui está o código:
\documentclass[review]{elsarticle}
\usepackage{lineno}
\modulolinenumbers[5]
\usepackage{cclicenses}
\usepackage{makecell}
\newcolumntype{C}[1]{>{\centering\arraybackslash}p{#1}} % centered 'p' col.
\usepackage{caption}
\usepackage{framed} % Framing content
\usepackage{nomencl} % Nomenclature package
\usepackage[font=small,skip=0pt]{caption}
\setlength{\nomitemsep}{-\parskip}\usepackage{booktabs,multirow}
\begin{document}
\begin{center}
\begin{tabular}{ c c c c }
\toprule
\makecell{Case of each letter} & first signification & second
singnification \\
\midrule
S with T\\ T with U& L & A & \\
Q with X\\ X with W & V & B & \\
Z with W\\ W with Y& M & C & \\
\bottomrule
\end{tabular}
\vspace{0.5\baselineskip}\vspace{-\parskip}
\captionof{table}{example}
\label{tab:SC}
\end{center}
\end{document}
por exemplo: L e A devem estar no meio de S com T e T com U e também quero um espaço entre as linhas 1 e 2 e entre as linhas 2 e 3
