使用 pgfplotstables 合并表格排版中的列标题

我有一张表格，其中的列很窄，除了列标题之外。我正在使用 pgfplots 排版表格，我需要一种方法来指定应合并某些标题列。

\documentclass[twocolumn]{article} 

\usepackage{pgfplotstable}
\usepackage{booktabs}


% set column separator for our csv loading package
\pgfplotstableset{col sep=comma}

\begin{document}

\begin{table*}
\centering
\scriptsize
\caption{caption}
\label{tab:hierarchical_vs_soa}
\pgfplotstabletypeset[
    begin table=\begin{tabular},
    header=true,
    every head row/.style={before row=\toprule, after row=\midrule},
    every last row/.style={after row=\bottomrule},
    every first row/.style={after row=\midrule},
    string type,
    columns/1/.style={column name=},
    columns/3/.style={column name=},
    columns/4/.style={column name=},
    columns/6/.style={column name=},
    columns/7/.style={column name=},
    columns/9/.style={column name=},
    end table=\end{tabular}
    ]{data.csv}
\end{table*}


\end{document}

使用示例 CSV 文件

header,,WIDETEXT,,,WIDETEXT MORE,,,WIDESTTEXTHERE, 
,A,B,C,A,B,C,A,B,C
A,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1
B,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1
C,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1

我怎样才能简单地实现这一目标？

我不知道如何自动执行此操作，但可以在选项\multicolumn中声明一个标题。before row

如您所见，第一行（宽文本标题）已被注释，第二行用作标题。

\documentclass{article}
\usepackage{booktabs}
\usepackage{pgfplotstable}

\begin{document}
\begin{table}
\centering
\pgfplotstabletypeset[
    every head row/.style={
        before row={%
            \toprule
            & \multicolumn{3}{c}{Widetext} & \multicolumn{3}{c}{Widetext more} & \multicolumn{3}{c}{Widetext here}\\
        },
        after row=\midrule,
    },
    every last row/.style={
        after row=\bottomrule},
    columns/0/.style ={column name={}},
    col sep=comma, row sep=\\,
    string type,
]{
%header,,WIDETEXT,,,WIDETEXT MORE,,,WIDESTTEXTHERE,\\ 
,A,B,C,D,E,F,G,H,I\\
A,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
B,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
C,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
}

\end{table}

这个解决方案存在一个问题（由@Ignasi 提供）：

\documentclass[twocolumn]{article} 

\usepackage{pgfplotstable}
\usepackage{booktabs}


\begin{document}
\begin{table}
\centering
\pgfplotstabletypeset[
    every head row/.style={
        before row={%
            \toprule
            & \multicolumn{3}{c}{Widetext} & \multicolumn{3}{c}{Widetext more} & \multicolumn{3}{c}{Widetext here}\\
        },
        after row=\midrule,
    },
    every last row/.style={
        after row=\bottomrule},
    columns/0/.style ={column name={}},
    col sep=comma, row sep=\\,
    string type,
]{
%header,,WIDETEXT,,,WIDETEXT MORE,,,WIDESTTEXTHERE,\\ 
,A,B,C,A,B,C,A,B,C\\
A,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
B,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
C,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
}
\caption{A very nice table}
\end{table}
\end{document}

“header”行被附加了“-index*”以保证唯一性。我是这样解决的：

\documentclass[twocolumn]{article} 

\usepackage{pgfplotstable}
\usepackage{booktabs}

\begin{document}
\begin{table}
\centering
\caption{A very nice table}
\pgfplotstabletypeset[
    header=false,
    every head row/.style={after row={\toprule header & \multicolumn{3}{c}{Widetext} & \multicolumn{3}{c}{Widetext more} & \multicolumn{3}{c}{Widetext here}\\ \midrule}},
    every first row/.style={after row=\midrule},
    every last row/.style={after row=\bottomrule},
    string type,
    columns/0/.style={column name=},
    columns/1/.style={column name=},
    columns/2/.style={column name=},
    columns/3/.style={column name=},
    columns/4/.style={column name=},
    columns/5/.style={column name=},
    columns/6/.style={column name=},
    columns/7/.style={column name=},
    columns/8/.style={column name=},
    columns/9/.style={column name=},
    col sep=comma, row sep=\\,
    string type,
]{
%header,,WIDETEXT,,,WIDETEXT MORE,,,WIDESTTEXTHERE,\\ 
,A,B,C,A,B,C,A,B,C\\
A,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
B,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
C,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1\\
}
\end{table}
\end{document}

但我不喜欢这个解决方案，因为由于不可见的空白标题以及必须指定每个列名，表格顶部会留下额外的空间。
