pfgplotstable 和 siunitx，.csv 文件中的单位列

pfgplotstable 和 siunitx，.csv 文件中的单位列

我在文件中有一些数据.csv，我想用pgfplotstable和的组合来排版siunitx。考虑以下（不是那么极简的）MWE，它会抛出错误

Undefined control sequence. \micro ->\ERROR l.49 ]{mytable.csv}\par

为什么会出错呢？

\documentclass[norsk,10pt,a4paper]{article}
\usepackage{babel}
\usepackage[utf8]{inputenc}
\usepackage{graphicx,parskip,url,xcolor,tabularx,array,adjustbox,booktabs}
\usepackage[showframe]{geometry}
\usepackage[hang,bf,small]{caption}
\usepackage{capt-of,pgfplotstable}
\usepackage{siunitx}
\sisetup{exponent-product = {\cdot},output-decimal-marker={,}, per-mode=symbol}

\begin{filecontents*}{mytable.csv}
Chem.;         Avg. Conc.;    Avg. Conc. Norm.;   Conc. Unit;                   Mass sum;      Mass unit

\end{filecontents*}

您的 MWE 有很多错误，我成功消除了其中的大部分，因此 MWE 现在至少可以编译......

编辑（1）： 同时，我翻遍了pgfplotstable手册和 SE，寻找答案中未解决的问题。这很有成效；我找到了我在纠正 MWE 中的错误时引入的错误……生成的新代码和所获表格的图像如下所示。

\documentclass[margin=5mm,preview]{standalone}

\sisetup{                           % setup siunitx ...

        round-precision = 2,        % to 3 places
        per-mode        = symbol,   % kg/dm^3 instead kgm^{-3}
      group-four-digits = true,     %   for 1 234,567       
        }
    \usepackage{booktabs}           % for table rules

如您所见，在表中我介绍了S列的类型并使用siunitx引擎对列进行数字格式化。

警告：由于列标题过长，该表比文档类\textwidth中的通常表更宽。article

编辑（2）： 同时，Stefan Pinnow 在他的评论中描述了替代解决方案（由于未知原因，该解决方案之前不起作用，现在我记不清是什么问题了 :-( ）。但是，下面给出了更正后的代码。

\documentclass[margin=5mm,preview]{standalone}
    \usepackage{siunitx} % Formats the units and values
\sisetup{                           % setup siunitx ...

        round-precision = 2,        % to 3 places
        per-mode        = symbol,   % kg/dm^3 instead kgm^{-3}
      group-four-digits = true,     %   for 1 234,567       
        }
    \usepackage{booktabs}           % for table rules

    \usepackage{pgfplotstable}      % Generates table from .csv
    \usepackage{filecontents}       % <--- important: enable table 
                                    % refreshing at each compilation

结果和以前一样！
