可以使用biblatex包来计算文档正文中使用引文的次数。这可以通过添加citecounter=true包选项来启用。即使使用此选项，默认情况下也会禁用浮点数内的引用计数，但它们也可以重新启用，因为回答经过莫威到Biblatex citecounter 不计算图片标题中的参考文献显示。下面的 MWE 采用了这种修改。
caption我还需要使用不幸篡改上述解决方案的软件包。现在，表格标题中的每个引用都是重复计算对于下面的 MWE，它显示了四个引用实例，而不是明显的两个。
我该如何解决这个问题？（可以对 MWE 进行简单的算术运算，但在我的实际文档中不可行）。
还有一些挥之不去的警告，例如
LaTeX Warning: There were undefined references.
Package biblatex Warning: Please (re)run Biber on the file:
(biblatex) VeaOtsing
(biblatex) and rerun LaTeX afterwards.
caption但无论是否存在这些似乎都存在，奇怪......

由于单行检查，字幕内容被处理两次。
您可以禁用检查：
\captionsetup{singlelinecheck=false}
或者在检查期间禁用 citetracker。caption 有一个（未记录的）钩子用于此：
\AtCaptionSingleLineCheck{\boolfalse{citetracker}}
