使用表中的值更新文本中的值

我正在使用 latex 进行研究，但确实遇到了一个问题。我希望能够使用表中的值自动更新我在文本中提到的值，这样当表中的值发生变化时，我在文本中提到的值也会发生变化。我偶然发现了这篇有用的帖子：通过“网格搜索”访问表中的值 但我仍然很难将它应用于下表

如果表的结构相同，可以执行以下操作：

\documentclass{article}
\usepackage{xparse,siunitx,booktabs}

\newcommand{\specialcell}[2][c]{\begin{tabular}[#1]{@{}c@{}}#2\end{tabular}}

\ExplSyntaxOn

\NewDocumentCommand{\definedata}{mm}

  \clist_map_inline:nn { #2 }

 }

\end{table}

We can retrieve the data: in Alberta, N1 is \retrievedata{first}{AB}{N1}.

数据被打包在属性列表中，您可以根据需要拥有任意数量的数据。

一个选项可能是使用pgfplotstable。这样您可以先使用 读取表格数据\pgfplotstableread，然后使用 排版该表格\pgfplotstabletypeset。可以使用 访问特定单元格\pgfplotstablegetelem（在下面的示例中放入一个新宏）。

可能需要一些时间去适应并弄清楚如何按照您喜欢的方式制作桌子。

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

\pgfplotstableread[
  col sep=semicolon,
]{

\textbf{Total};20781;100.0;32690;100.0
}\FirstDataset

\pgfplotstableset{
  ints/.style={
    dec sep align,
    column name=#1,
    1000 sep=\,
  },
  ints/.default={},
  1dec/.style={
    dec sep align,
    fixed,
    fixed zerofill,
    precision=1,
    column name=#1
  },
  1dec/.default={}
}

\newcommand\getvaluefromtable[4][]{%
  \pgfplotstablegetelem{#3}{#4}\of#2%
  \pgfmathprintnumber[1000 sep=\,,#1]{\pgfplotsretval}%
}

\begin{document}

\pgfplotstabletypeset[
  every head row/.style={
    before row={
      \toprule
     & \multicolumn{4}{c}{Built dataset} & \multicolumn{4}{c}{Scott's database} \\ \cmidrule(lr){2-5} \cmidrule(lr){6-9}
    },
   after row={\midrule}
  },
  every last row/.style={after row=\bottomrule},
  columns/Province/.style={
    string type,
    column type=l,
    column name=\textbf{Province}
  },
  columns/N1/.style={ints=\textbf{N}},
  columns/S1/.style={1dec=\textbf{Sum}},
  columns/N2/.style={ints=\textbf{N}},
  columns/S2/.style={1dec=\textbf{Sum}}
]{\FirstDataset}

\bigskip

Access values by table name, row number and column name, \textit{e.g.}  \getvaluefromtable{\FirstDataset}{10}{N2}

You can use a numeric index for the column as well: \getvaluefromtable{\FirstDataset}{1}{[index]2}.
Indices are zero-based, hence 14.3 for row 1, column 2.
