I have code for creating a table but I came up with a problem:
\documentclass[11pt, a4paper, twoside]{Thesis} % Paper size, default font size and one-sided paper
\graphicspath{{./Pictures/}} % Specifies the directory where pictures are stored
\usepackage[square, numbers,rotating, comma, fancyhdr,here,longtable ,sort&compress,caption, booktabs,pifont,epsfig,subfig ,enumitem,array,subcaption, cleveref,subfigure ,tabularx, textcomp, placeins,graphicx, url, blindtext,verbose{placeins}]
\begin{document}
\begin{table}[htp]
\caption{The correlation between wireless sensor nodes [25--28--29--31--32] }
\label{tab: cor}
\centering
\footnotesize\setlength{\tabcolsep}{2.5pt}
\begin{tabular}{l@{\hspace{6pt}} *{5}{c}}
\toprule
\bfseries Node Name & \multicolumn{5}{c}{\bfseries Node name} \\
\cmidrule(l){3-5}
& 25 & 28 & 29 & 31 & 32 \\
\midrule
\bfseries Node 25
& 1.00 & 0.96 & 0.92 & 0.97 & 0.97 \\
\bfseries Node 28
& 0.96& 1.00 & 0.93 & 0.97 & 0.96 \\
\bfseries Node 29
& 0.92 & 0.93 & 1.00 & 0.92 & 0.94 \\
\bfseries Node 31
& 0.97 & 0.97 & 0.92 & 1.00 & 0.96 \\
\bfseries Node 32 \\
& 0.97 & 0.96 & 0.94 & 0.96 & 1.00 \\
\bottomrule
\addlinespace
\end{tabular}
\end{table}
\end{document}
The problem is highlited where the row doesn't placed in a proper place.

Node 32. Delete it and everything will go back to its place. – Ignasi Feb 6 at 9:52
