I'm a beginner user of Latex , i wana drow a table but i got this

i wana add the lines between the rows, also the caption in the center and expand the cells.

\documentclass{article}
\usepackage{multirow}
\usepackage{array}
\begin{document}
\begin{table}
\centering
\begin{tabular}{|>{\bfseries}c|*{4}{c|}}\hline
\multirow{2}{*}{\bfseries Algorithme} &
\multicolumn{2}{c|}{\bfseries 2-hop} \\\cline{2-5} & \textbf{node}       & \textbf{true?} \\ \hline
R-ELM         & Normal              & No             \\ \hline
Q-ELM         & Normal              & No             \\ \hline
\end{tabular}
\caption{some table}
\end{table}
\end{document}

• please, extend your code snipped to small but complete document beginning with ˙\documentclass{...} and ending with \end{document}. In preamble load only necessary packages. – Zarko Jun 29 '17 at 12:04
• What you want is not clear. You declare 5 columns but write 3. Further, the caption is centred by default, so there must be something in the ret of your code which does that. – Bernard Jun 29 '17 at 12:09
• see, if \documentclass{article} \usepackage{array, multirow} \begin{document} \begin{table} \centering \begin{tabular}{|>{\bfseries}c| *{2}{c|} } \hline \multirow{2}{*}{Algorithme} & \multicolumn{2}{c|}{\textbf{2-hop}} \\ \cline{2-3} & \textbf{node} & \textbf{true?} \\ \hline R-ELM & Normal & No \\ \hline Q-ELM & Normal & No \\ \hline \end{tabular} \caption{some table} \end{table} \end{document}  gives what you want. – Zarko Jun 29 '17 at 12:17
• @Zarko thank you so mush , i wana also expand the cells width , Can you help? – Hala Elomrani Jun 29 '17 at 12:22
• how to expand cells? cells' widths are (now) determined with their content, however You can increase columns separation. See my answer below. – Zarko Jun 29 '17 at 13:34

\documentclass{article}
\usepackage{array, multirow}

\begin{document}
\begin{table}
\setlength\tabcolsep{18pt}% default value is 6pt
\centering
\begin{tabular}{|>{\bfseries}c| *{2}{c|} }
\hline
\multirow{2}{*}{Algorithme} & \multicolumn{2}{c|}{\textbf{2-hop}}   \\
\cline{2-3}
& \textbf{node} & \textbf{true?}        \\
\hline
R-ELM               & Normal    & No                        \\
\hline Q-ELM            & Normal    & No                        \\
\hline
\end{tabular}
\caption{some table}
\end{table}
\end{document}
