Good night,
I'm using the Elsevier journal template, I need to set up a table like Image 1. I'm a beginner in TeX and I still have not understood how to merge cells into a table. Ideally, the table should be in the format of Image 2. The code I have in the template is:
\begin{table}[h]
\centering
\begin{tabular}{l l l l l}
\hline
\textbf{Author} & \textbf{Year} & \textbf{Blockchain} & \textbf{Implementation}\\
\hline
{[31]} & 2018 & Ethereum & None \\
{[33]} & 2018 & Ethereum & Simulation \\
{[34]} & 2017 & Ethereum & Simulation \\
{[36]} & 2018 & Ethereum & Complete \\
{[37]} & 2017 & Ethereum & Simulation \\
\hline
\end{tabular}
\caption{Related Work.}
\end{table}
Table from template:
Table I need:
The second image I did in Word, but it must be in the format of the template I'm using.
