长表文件内容未编译

Question

我正在尝试获取如下简单的表格：

我正在使用，longtable因为我在文件中有数据.dat。

您能帮助我通过从文件导入数据成功生成表格吗？

以下是我目前所掌握的信息：

\documentclass{book}
\usepackage{calc}
\usepackage[left=1.5cm, right=1.5cm, bindingoffset=1.5cm, headheight=30pt, top={120pt+10mm}]{geometry}
\usepackage{pgfplotstable}
\usepackage{longtable}
\usepackage{filecontents}

\begin{filecontents}{data133.dat}
X   2,7 3,6 2,5 3,5 3,3 2,2 5,1 6,2 8,1 6,4 4,8 5,8 9,5 9,9 9,4 8,9 8,8 6,9 7,4 4,4
Y   +1  +1  +1  +1  +1  +1  +1  +1  +1  +1  -1  -1  -1  -1  -1  -1  -1  -1  -1  -1
\end{filecontents}%

\begin{document}

    \pgfplotstableset{

        }
    }
}{
    % versions up to and including 1.5.1 need this:

            typeset cell/.append code={%
                \ifnum\pgfplotstablerow=-1 %
                    \pgfkeyssetvalue{/pgfplots/table/@cell content}{}%
                \fi
            }
        }
    }
}

\pgfplotstableset{
begin table=\bgroup\small\setlength{\tabcolsep}{10pt}\begin{longtable}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|},
end table=\end{longtable}\egroup,
}

\pgfplotstabletypeset[col sep=space,empty header, rows = {X,Y},
]{data133.dat}

\end{document} 

Answer 1

一个要求是，字段宽度包含的\specialtable列数大于或等于数据文件中预期的最大列数。

我擅自以数学模式设置了表格内容。

已编辑（2016 年 12 月），删除了每个文件记录末尾的空格要求。已升级为 2016-11-07readarray版本的首选语法。

\documentclass{book}
\usepackage[left=1.5cm, right=1.5cm, bindingoffset=1.5cm, headheight=30pt, 
  top={\dimexpr120pt+10mm}]{geometry}
\usepackage{readarray}[2016-11-07]
\usepackage{filecontents}
\begin{filecontents*}{data133.dat}
X   2,7 3,6 2,5 3,5 3,3 2,2 5,1 6,2 8,1 6,4 4,8 5,8 9,5 9,9 9,4 8,9 8,8 6,9 7,4 4,4
Y   +1  +1  +1  +1  +1  +1  +1  +1  +1  +1  -1  -1  -1  -1  -1  -1  -1  -1  -1  -1
\end{filecontents*}%
\newcommand\digest[1]{%
  \edef\tmp{\mydata[#1]}%
  \expandafter\digestaux\tmp{} \relax%
}
\def\digestaux#1 #2\relax{$#1$\ifx\relax#2\relax\else\digestauxB#2\relax\fi}
\def\digestauxB#1\relax{&\digestaux#1\relax}
\newcommand\specialtable[1]{%
  \noindent
  \tabcolsep=4pt\relax%
  \readrecordarray{#1}\mydata%
% THE FOLLOWING LINE MUST ALLOW FOR THE MAX. NUMBER OF COLUMNS EXPECTED
  \begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}
  \hline\digest{1}\\\hline\digest{2}\\\hline
  \end{tabular}%
}
\begin{document}
\specialtable{data133.dat}
\end{document}

如果您可以添加虚拟标头，则以下内容似乎有效。

\documentclass{standalone}
\usepackage{calc}
% \usepackage[left=1.5cm, right=1.5cm, bindingoffset=1.5cm, headheight=30pt,
% top={120pt+10mm}]{geometry}
\usepackage{pgfplotstable}
\usepackage{longtable}
\usepackage{filecontents}

\begin{filecontents*}{data133.dat}
Z   x  x  x  x  x  x  x  x  x  x  x  x  x  x  x  x  x  x  x  x
X   2,7 3,6 2,5 3,5 3,3 2,2 5,1 6,2 8,1 6,4 4,8 5,8 9,5 9,9 9,4 8,9 8,8 6,9 7,4 4,4
Y   +1  +1  +1  +1  +1  +1  +1  +1  +1  +1  -1  -1  -1  -1  -1  -1  -1  -1  -1  -1
\end{filecontents*}%

\begin{document}

    }
}{
    % versions up to and including 1.5.1 need this:

                \fi
            }
        }
    }
}

% \pgfplotstableset{
