Answer 1

正如评论中提到的那样：S列中的文本应该放在花括号内。由于最后一行的文本中没有包含花括号，所以你得到了上述错误。

顺便说一句，您的表格太宽了，无法放入文本区域（这是未知的，因为您没有提供 MWE，而只是提供代码片段），所以我建议在表格设计上做一些微小的改动：

\documentclass{article}
\usepackage{geometry}
\usepackage{booktabs, makecell}
\renewcommand\theadfont{\small\bfseries}
\renewcommand\theadgape{}
\newlength\colwidth
\usepackage[skip=1ex,labelfont=bf,font=small]{caption}
\usepackage{siunitx}

\begin{document}
\begin{table}[ht]
\centering
\caption{Proposed and benchmark forecasting frameworks}
\label{tab:Comput}
    \setlength{\tabcolsep}{0pt}
    \sisetup{round-mode=places,
             round-precision=2,
             table-format=1.2,
             }
    \settowidth\colwidth{complexity (level)}
\begin{tabular*}{\columnwidth}{ @{\extracolsep{\fill}}  
                                p{\colwidth}  *{5}{S} }
    \toprule
 & \multicolumn{5}{c}{\thead{Computational efficiency}} \\
    \cmidrule{2-6}
\thead{Months}
    & {\thead{FS-ANN}}
        & {\thead{Bi-level}}
            & {\thead{AFC-STLF}}
                & {\thead{MI-mEDE-ANN}}
                     & {\thead{FS-FCRBM-GWDO}} \\
\midrule
    Computational complexity (level) & {Low} & {High} & {Moderate} & {High} & {Moderate} \\

\midrule
Avg.& 2.12 & 1.79 & 1.44 & 0.410\\
\bottomrule
\end{tabular*}
\end{table} 
\end{document}

Answer 2

这应该有帮助

\begin{table}[ht]
    \centering
    \caption{Evaluation of the proposed }
    \label{tab:Comput}
    \setlength{\tabcolsep}{0pt}
    \sisetup{round-mode=places,
        round-precision=2,
        table-format=1.2,
    }
    \begin{tabular}{l*{5}{S}}                                                \toprule
                 & \multicolumn{5}{c}{Proposed and benchmark forecasting frameworks} \\                       \cmidrule{2-6}
        {Months} & {FS-ANN} & {Bi-level} & {AFC-STLF} & {MI-mEDE-ANN} & {FS-FCRBM-GWDO} \\         \cmidrule{1-6}
        {Computational complexity (level)} & {Low} & {High} & {Moderate} & {High} & {Moderate} \\   \cmidrule{1-6}
        Avg.& 2.12 & 1.79 & 1.44 & 0.410&\\                                                           \bottomrule
    \end{tabular}
\end{table}
