设置表格的正确尺寸时出错

Question

这是我生成此表的努力。我想知道为什么我会出错？错误是“未定义序列”。或者，欢迎使用任何更好的格式来制表以下示例数据。

\begin{table}
  \centering
  \captionsetup{width=10cm}
  \caption{Initial, post-etch and post SPM treatment heights.}
  \label{tab:2}
  \begin{tabular}{l *{3}{S[table-format=4.0]}}
    \toprule
           {Wafer \#} & {Initial height} & {Post-etch height}&{Post SPM treatment} &{SPM treatment}$ \\
            & \si{\mu m} & \si{\mu m} &\si{nm}\\
    \midrule
     $Length (mm)$  &       1.4725 &        1.5875 &        142.5 & 112\\
     $Width (mm)$     &      1.4725 &        1.575&        142.5& 113 \\
     $Thickness (mm)$   &       1.495 &        1.5925&        132.5& 145 \\
     $Young modulus (GPa))$  &       1.492 &        1.66 &        190& 456\\
     $Young modulus (GPa)$    &       1.465 &        1.63&        197.5& 5454 \\
     $TYoung modulus (GPa)$    &       1.2525 &        1.4625&        192.5 & 543\\
      $Young modulus (GPa)$    &       1.2525 &        1.4625&        192.5& 903 \\
       $Boundary conditions$    &       1.2525 &        1.4625&        192.5& 5353 \\
        $Applied load$    &       1.2525 &        1.4625&        192.5& 434 \\
         $Young modulus (GPa)$    &       1.2525 &        1.4625&        192.5& 5345 \\
    \bottomrule
  \end{tabular}
\end{table}

这是有效的，请注意已加载的包和表的更改。

\documentclass{article}
\usepackage{siunitx,booktabs,caption}

\begin{document}

\begin{table}
\centering
\captionsetup{width=10cm}
\caption{Initial, post-etch and post SPM treatment heights.}
\label{tab:2}

\begin{tabular}{
  l 
  S[table-format=1.4]
  S[table-format=1.4]
  S[table-format=3.1]
  S[table-format=4.0]
}
\toprule
{Wafer \#} & {Initial} & {Post-etch} & {Post SPM}  & {SPM} \\
           & {height}  & {height}    & {treatment} & {treatment} \\
  & \si{\micro\meter}
  & \si{\micro\meter}
  & \si{\nano\meter} \\
\midrule
Length (\si{mm})          & 1.4725 & 1.5875 & 142.5 &  112 \\

我建议这样做，另外使用makecell：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[showframe]{geometry}
\usepackage{siunitx, booktabs, caption, makecell}
\DeclareSIUnit\micron{\micro\metre}
\renewcommand\theadfont{\normalsize\upshape}

\begin{document}

\begin{table}
  \centering
  \captionsetup{width=10cm}\setlength\extrarowheight{3pt}
  \caption{Initial, post-etch and post SPM treatment heights.}
  \label{tab:2}
  \begin{tabular}{ @{}>{\itshape}l *{2}{S[table-format=1.4]}S[table-format=3.1]S[table-format=4.0]}
    \toprule
           {\thead{Wafer \#\\ (\si{\micron})}} & {\thead{Initial height\\ (\si{\micron})}} & {\thead{Post-etch \\ height  (\si{\micron})}}
            & {\thead{Post SPM\\ treatment  (\si{\nm})}} & {\thead{SPM\\ treatment}} \\
    \midrule
     Length (mm) & 1.4725 & 1.5875 & 142.5 & 112\\
     Width (mm) & 1.4725 & 1.575& 142.5& 113 \\
     Thickness (mm) & 1.495 & 1.5925& 132.5& 145 \\
     Young modulus (GPa) & 1.492 & 1.66 & 190& 456\\
     Young modulus (GPa) & 1.465 & 1.63& 197.5& 5454 \\
    TYoung modulus (GPa) & 1.2525 & 1.4625& 192.5 & 543\\
     Young modulus (GPa) & 1.2525 & 1.4625& 192.5& 903 \\
     Boundary conditions & 1.2525 & 1.4625& 192.5& 5353 \\
     Applied load & 1.2525 & 1.4625& 192.5& 434 \\
     Young modulus (GPa) & 1.2525 & 1.4625& 192.5& 5345 \\
    \bottomrule
  \end{tabular}
