我如何才能使 PGFPlots 表居中和小数对齐？

Question

以下是我正在使用的代码：

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{measurements.dat}
sample num-bugs num-part other-measure another
   5       80      190        200        210
  15      520      410        430        350
  25      650      640        630        900
  35     1100     1200       1150       1020
\end{filecontents}

\usepackage{pgfplots, pgfplotstable, booktabs, colortbl}
\pgfplotsset{compat=1.7}
\pgfplotstableset{
  every head row/.style=
    {before row={\toprule},
     after row={\midrule}},
  every last row/.style=
    {after row={\bottomrule}},
  every even row/.style=
    {before row={\rowcolor[gray]{0.9}}},
  columns/.style=
    {dec sep align,
    %column type=c
    }
  }

\begin{document}
\pgfplotstabletypeset[
  columns={sample, another, num-part},
  columns/sample/.style={
    column name={Sample},
  }
  ]{measurements.dat}
\end{document}

这会导致数据按预期在小数点处对齐。但是，数据也在 处对齐l。我需要它在 处对齐c，因此我添加了选项

columns/.style={column type=c}

（如上文注释所示）。

这会产生错误：

ERROR: Extra alignment tab has been changed to \cr.

<template> \endtemplate 

l.31   ]{measurements.dat}

--- HELP ---
There are too many separate items (column entries) in a single row of
an array or tabular environment. In other words, there were too many &
's before the end of the row. You probably forgot the \\ at the end of
the preceding row.

我怎样才能实现居中和对齐列？

当前左对齐结果

这对你有用吗？它用于格式化列。和siunitx之间似乎存在一些问题，因此必须单独格式化每列，并且必须在括号中提供列名。如果不行，siunitx 会抱怨每个siunitxpgfplotstable埃在列名中。也许这里的一些巫师知道如何解决这个问题。
