我怎样才能在 A4 纸上制作这个表格

Question

我目前拥有的代码是：

\documentclass{article}
\usepackage{geometry}
  \geometry{a4paper,   % note: 'a4paper', not 'a3paper'
            showframe, % omit 'showframe' option in real document
            %total={170mm,300mm},
            %left=20mm, top=20mm,
            margin=20mm
  }
\usepackage{siunitx,booktabs}
\newcolumntype{T}[1]{S[table-format=#1]}

\begin{document}
\begin{center}
\sisetup{round-mode=places,round-precision=2}
\begin{tabular}{ @{} 
                 T{1.2} 
                 *{5}{T{2.2}} 
                 S[table-format=2.3,round-precision=3] 
                 S[table-format=1.3,round-precision=2] X @{}}

但这只会产生

我怎样才能实现这个目标？

Answer 1

• 对于最后一列X，您使用未定义的列（您未加载tabularx包。
• 定义表列的数量（9）和使用的列数（10）不匹配，补救措施是在其定义中添加一列。
• 为了更好地间隔文本块中的表格，请在多行单元格中写入合理的正弦列标题（第一个和最后一个三个）：

附录：

• 使用 `tabular* 表格可以更好地在文本中留出空间，
• 由于某些列中的所有数字都具有相同的格式，因此它们也可以在c列中很好地对齐（就像现在已经在最后两列中一样），MWE 可以简化为：

            margin=20mm,
            showframe,
            }
\usepackage{booktabs, multirow, siunitx}

\begin{document}
