I tried using the following code, with an unexpected outcome shown below (I've also attached the outcome I am expecting):
\documentclass{article}\usepackage{siunitx}\usepackage{array,booktabs}\begin{document}\begin{table} \begin{tabular*}{\textwidth}{@{\extracolsep{\fill}}lSS@{}} \\\toprule&{\textit{Score}}\\\midrule \textbf{class 1} & 0 \\ \midrule&\multicolumn{2}{cc}{\textbf{Model A}\textbf{Model B}}\\ \midrule \textbf{class A} 0 & 0\\ \textbf{class B} 0 & 0\\ \textbf{class C} 0 & 0\\ \textbf{class D} 0 & 0\\ \midrule \textbf{class X} 0 & 0\\ \textbf{class Y} 0 & 0\\ \textbf{class Z} 0 & 0\\ \bottomrule \end{tabular*} \caption{caption here} \label{table:results}\end{table}\end{document}This has three major issues shown below: (1) the alignment of "Score" should be centered, (2) Model A Model B are repeating, and (3) the 0 values are shifted towards the left
I am trying to get an output which looks like:
