# Multicolumn alignment

I am writing an article, but I have a problem when I write this table

\begin{table}[H]
\centering
\caption{atomic composition of the different points analyzed by the DES probe}
\label{DES probe}
\begin{tabular}{
c
*{13}S[table-format=2.1]
}
\toprule
& \multicolumn{2}{c}{\bfseries{Weight\%}}\\
\cmidrule(lr){2-14}
{\bfseries{Point}} & {\boldmath{C}}    & {\boldmath{O}}    &
{\boldmath{Mg}}    & {\boldmath{Al}}    & {\boldmath{Si}}    & {\boldmath{S}}     & {\boldmath{K}}     & {\boldmath{Ca}} & {\boldmath{Ti}} & {\boldmath{Fe}} & {\boldmath{Zn}} & {\boldmath{Cu}} & {\boldmath{Pd}}  \\
\midrule

A & 0.0 & 50.5 & 1.6 & 7.4 & 24.3 & 7.9 & 0.0 & 0.0 & 0.0 & 6.2 & 0.6 & 0.0 & 1.5 \\

B & 32.1 & 46.2 & 0.2 & 1.9 & 5.9 & 1.9 & 0.7 & 0.7 & 0.3 & 9.6 & 0.0 & 0.5 & 0.0\\

C & 0.0 & 43.0 & 0.0 & 3.6 & 10.8 & 6.7 & 1.1 & 3.2 & 0.4 & 31.1 & 0.0 & 0.0 & 0.0 \\
\bottomrule
\end{tabular}
\end{table}


The title "weight %" don't appear centered in the multicolumn arrangement.

Could anybody help me to fix it?

Thank you very much!

• welcome to tex.se! please. extend your table code to small, but complete document beginning with \documentclass{...} and ending with \end{document}. help us to help you! – Zarko Nov 6 '17 at 23:10
• if you like to have "weight" on the middle of columns with numbers, than you should write: \multicolumn{13}{c}{\bfseries{Weight (\%)}}\ – Zarko Nov 6 '17 at 23:14
• {\boldmath{C}} is the same as C as \boldmath is a declaration that makes any later math be bold but there is no math in the scope of the cell. – David Carlisle Nov 6 '17 at 23:26

let me elaborate my comment above:

\documentclass{article}
\usepackage{geometry}
\usepackage{siunitx}
\usepackage{booktabs, makecell}
\usepackage[skip=1ex, labelfont=bf]{caption}

\begin{document}
\begin{table}
\centering
\caption{atomic composition of the different points analyzed by the DES probe}
\label{DES probe}
\begin{tabular}{@{} c
*{13}S[table-format=2.1]
@{} }
\toprule
\cmidrule(lr){2-14}
\midrule
A & 0.0  & 50.5 & 1.6 & 7.4 & 24.3 & 7.9 & 0.0 & 0.0 & 0.0 &  6.2 & 0.6 & 0.0 & 1.5\\
B & 32.1 & 46.2 & 0.2 & 1.9 &  5.9 & 1.9 & 0.7 & 0.7 & 0.3 &  9.6 & 0.0 & 0.5 & 0.0\\
C & 0.0  & 43.0 & 0.0 & 3.6 & 10.8 & 6.7 & 1.1 & 3.2 & 0.4 & 31.1 & 0.0 & 0.0 & 0.0\\
\bottomrule
\end{tabular}
\end{table}
\end{document}
