（如何）将 CSV 数据转置以在表格中显示

Question

我可以使用 csvsimple 包在表格环境中自动显示来自 CSV 文件的数据。是否可以以转置形式（行转为列，反之亦然）实现相同的功能，如第二个手工编码的示例所示？

\begin{filecontents*}{transpose.csv}
course,J,Js,F,Fs,G,Gs,T,Ts
1,4,4,4,4,3,3,5,5
2,3,7,2,6,2,5,4,9
3,4,11,3,9,5,10,2,11
4,2,13,7,16,3,13,7,18
5,7,20,3,19,7,20,7,25
6,5,25,3,23,7,27,2,27
7,3,28,5,28,2,29,3,30
8,6,34,4,32,7,36,3,33
9,4,38,2,34,3,39,7,40
10,4,42,2,36,6,45,2,42
\end{filecontents*}

\documentclass{article}
\usepackage{booktabs}
\usepackage{csvsimple}

\begin{document}
\centering

\begin{tabular}{rcccc}
  \toprule
  \# & Subj J & Subj F & Subj G & Subj T \\
  \midrule
    \csvreader[head to column names,late after line=\\]{transpose.csv}{}%
    {\course & \J & \F & \G & \T}
  \bottomrule
\end{tabular}

\vspace{2em}

\begin{tabular}{lcccccccccc}
  \toprule
  \# & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\
  \midrule
  Subj J & 4 & . & . & . & & &  &  &  & 4 \\
  Subj F & 4 & . & . &  & & &  &  & . & 2 \\
  Subj G & 3 & . &  &  & & &  & . & . & 6 \\
  Subj T & 5 &  &  &  & & & . & . & . & 2 \\
  \bottomrule
\end{tabular}

\end{document}

Answer 1

我的第一个想法是使用pgfplotstablecolumns。您可以通过宏中的键选择要绘制哪些列（原始表的列）\pgfplotstabletranspose。colnames from键表示我希望转置表的列根据course原始表列中的值命名。该行在每个课程主题之前postproc cell content添加。Subj

begin{filecontents*}{transpose.csv}
course,J,Js,F,Fs,G,Gs,T,Ts
1,4,4,4,4,3,3,5,5
2,3,7,2,6,2,5,4,9
3,4,11,3,9,5,10,2,11
4,2,13,7,16,3,13,7,18
5,7,20,3,19,7,20,7,25
6,5,25,3,23,7,27,2,27
7,3,28,5,28,2,29,3,30
8,6,34,4,32,7,36,3,33
9,4,38,2,34,3,39,7,40
10,4,42,2,36,6,45,2,42
\end{filecontents*}

\documentclass{article}
\usepackage{booktabs}
\usepackage{pgfplotstable}
\pgfplotsset{compat=1.10}

\begin{document}

\pgfplotstableread[
    col sep=comma,
]{transpose.csv}\normal

\pgfplotstabletranspose[
    colnames from=course,
    columns={course,J,F,G,T},
]\transpose\normal

\begin{center}
\pgfplotstabletypeset[
    string type,
    every head row/.style={before row=\toprule, after row=\midrule},
    every last row/.style={after row=\bottomrule},
    every col no 0/.style={
        column type={l},
        column name={\#},
        postproc cell content/.append style={/pgfplots/table/@cell content/.add={Subj }{}},
    },
]\transpose
\end{center}

\end{document}

Answer 2

我的想法是逐步建立每条数据行的转置行。之后，生成表格：

\begin{filecontents*}{transpose.csv}
course,J,Js,F,Fs,G,Gs,T,Ts
1,4,4,4,4,3,3,5,5
2,3,7,2,6,2,5,4,9
3,4,11,3,9,5,10,2,11
4,2,13,7,16,3,13,7,18
5,7,20,3,19,7,20,7,25
6,5,25,3,23,7,27,2,27
7,3,28,5,28,2,29,3,30
8,6,34,4,32,7,36,3,33
9,4,38,2,34,3,39,7,40
10,4,42,2,36,6,45,2,42
\end{filecontents*}

\documentclass{article}
\usepackage{booktabs,etoolbox}
\usepackage{csvsimple}

\begin{document}
\centering

\begin{tabular}{rcccc}
  \toprule
  \# & Subj J & Subj F & Subj G & Subj T \\
  \midrule
    \csvreader[head to column names,late after line=\\]{transpose.csv}{}%
    {\course & \J & \F & \G & \T}
  \bottomrule
\end{tabular}

\vspace{2em}

% These macros save the data
\def\columnAll{}
\def\courseAll{}
\def\JAll{}
\def\FAll{}
\def\GAll{}
\def\TAll{}

% Reading data and store into the auxiliary macros
\csvreader[head to column names]{transpose.csv}{}%
  {\edef\columnAll{\columnAll c}
   \edef\courseAll{\courseAll&\course}%
   \edef\JAll{\JAll&\J}%
   \edef\FAll{\FAll&\F}%
   \edef\GAll{\GAll&\G}%
   \edef\TAll{\TAll&\T}}%

% Finally: output as table
\begin{tabular}{l\columnAll}
  \toprule
  \# \courseAll\\
  \midrule
  Subj J \JAll\\
  Subj F \FAll\\
  Subj G \GAll\\
  Subj T \TAll\\
  \bottomrule
\end{tabular}

\end{document}
