我怎麼能讓這張桌子像我所包含的圖片一樣更大更寬？我的看起來又小巧又小
答案1
您可能會使用siunitx：
\documentclass{article}
\usepackage{siunitx}
\sisetup{uncertainty-mode=separate}
\begin{document}
\begin{table}[htp!]
\centering
\begin{tabular}{
|>{\vphantom{$\bigg|$}}r|
S[table-format=1.1] |
S[table-format=2.4(1)] |
S[table-format=1.3(1)] |
r|
S[table-format=-1.1] |
S[table-format=1.0] |
S[table-format=-1.4(1)] |
}
\hline

不過，我建議採用不同的外觀。
