将文本/标题置于列中央

Question

我想将标题“Normal”、“Student-t”和“GED”置于两列的中心，使它们直接位于栏的正上方。

\documentclass{article}
\usepackage{booktabs,siunitx}
\sisetup{table-format=1.3} % default numerical column spec
\begin{document}

\begin{table}
\sisetup{table-format=1.3}
\centering
\begin{tabular}{
  l
  S[table-format=2]
  S[table-format=1.3]
  SS
  l
  S[table-format=1.3]
  S[table-format=1.3]
  S
  l
  l
  S[table-format=2]
  S[table-format=1.3]
  SS
}

\bottomrule
\addlinespace
 &  & {Normal}  &  &  & {Student-t} &  &  & {GED} \\
\cmidrule(lr){3-4} \cmidrule(lr){6-7}  \cmidrule(lr){9-10} % center non-numerical info (A, B, ...) by placing them in braces
 & {s}  & {KLIC} & {CSL} &   & {KLIC} & {CSL} &  & {KLIC} & {CSL} \\

Answer 1

您可以使用\multicolumn将两列居中：

\documentclass{article}
\usepackage{booktabs,siunitx}
\sisetup{table-format=1.3} % default numerical column spec
\begin{document}

\begin{table}
\sisetup{table-format=1.3}
\centering
\begin{tabular}{
  l
  S[table-format=2]
  S[table-format=1.3]
  SS
  l
  S[table-format=1.3]
  S[table-format=1.3]
  S
  l
  l
  S[table-format=2]
  S[table-format=1.3]
  SS
}
