如何交叉引用不同計數器的標題？

Question

我不提供解決方案，因為您還沒有弄清楚您是將其用作學習練習還是實際用途，所以我不知道該給出哪種答案。

這是「為什麼？」的回答。而不是“如何？”

每次您在環境\caption中使用時figure，figure計數器都會增加。資訊寫入.aux文件以供交叉引用等使用。

您已經更改了標題標籤格式的外觀，但尚未觸及所使用的計數器。您的格式不使用所使用的計數器。也就是說，它不使用figure.所以你看不到figure環境本身所使用的價值。您只能看到您的自訂計數器。但這些並沒有用於交叉引用。因此，當您稍後引用它時，您將獲得寫入的信息.aux，它使用figure.並且您指定的格式此處未激活，因此這次使用計數器的值。

要了解發生了什麼，請查看.aux：

\relax
\@writefile{toc}{\contentsline {chapter}{\numberline {1}Chapter One}{1}{}\protected@file@percent }
\@writefile{lof}{\addvspace {10\p@ }}
\@writefile{lot}{\addvspace {10\p@ }}
\@writefile{lol}{\contentsline {lstlisting}{indentfirst.sty}{1}{}\protected@file@percent }
\providecommand*\caption@xref[2]{\@setref\relax\@undefined{#1}}
\newlabel{the-first-text}{{1.1b}{1}{}{}{}}
\newlabel{sub@the-first-text}{{b}{1}{}{}{}}

請注意，這些使用的是我們所期望的。

\@writefile{lof}{\contentsline {figure}{\numberline {1.1}{\ignorespaces This is a figure with some text, use the Figure counter.}}{1}{}\protected@file@percent }
\newlabel{group1}{{1.1}{1}{}{}{}}

這是我們的第一個數字。

\@writefile{lol}{\contentsline {lstlisting}{indentfirst.sty}{2}{}\protected@file@percent }
\@writefile{lof}{\contentsline {figure}{\numberline {1.2}{\ignorespaces This is just text B, so use the Listing counter.}}{2}{}\protected@file@percent }
\newlabel{group2}{{1.2}{2}{}{}{}}

在這裡我們看到為第二個浮點數寫入的資訊。請注意，寫入的值.aux正在使用figure計數器，即使在標題格式的任何地方都沒有使用它。

\@writefile{lof}{\contentsline {figure}{\numberline {1.3}{\ignorespaces This is just a figure, so use the Figure counter.}}{2}{}\protected@file@percent }
\newlabel{group3}{{1.3}{2}{}{}{}}
\@writefile{lol}{\contentsline {lstlisting}{indentfirst.sty}{3}{}\protected@file@percent }

現在我們得到3第三個浮點數。同樣，的值figure不用於排版標題。

\newlabel{text-c}{{1.4a}{3}{}{}{}}
\newlabel{sub@text-c}{{a}{3}{}{}{}}

再次，我們讓figure計數器遞增，儘管這並不意味著是，figure因為它發生在figure環境內部。

\@writefile{lol}{\contentsline {lstlisting}{indentfirst.sty}{3}{}\protected@file@percent }
\@writefile{lof}{\contentsline {figure}{\numberline {1.4}{\ignorespaces These are texts C and D, so use the Listing counter.}}{3}{}\protected@file@percent }
\newlabel{group4}{{1.4}{3}{}{}{}}
\gdef \@abspage@last{3}

如果您希望查看已編譯文件中發生的情況，這裡的一些程式碼可能會有所幫助。你必須編譯它，因為我的圖像由於 Okular 錯誤而無法使用。請注意：實際輸出非常難看。

\textbf{Cross references:}

Figure~\ref{group1} has the figureA and textA. Listing~\ref{the-first-text} is within the same Figure~\ref{group1}.

Listing~\ref{group2} only has the textB.

Figure~\ref{group3} only has the figureB.

Listing~\ref{group4} has the texts C and D. And sub-listing~\ref{text-c} is textC.
