biblatex 反向编号

Question

我发现这个很好的答案。但是，我在引用数 >=10 时遇到了对齐问题。

例如：

请注意，>= 10 的项目比 <9 的项目缩进更多。我希望所有项目都遵循（默认）相同的对齐方式。

下列的答案我用了：

Answer 1

这里的问题是biblatex需要测量数字标签的宽度以进行正确对齐。这通常发生在从文件中读取条目时.bbl。由于编号会根据文件中的条目数而变化.bbl，因此在数据输入时获得的宽度测量是不正确的。

现代最快的解决方案biblatex可能是将选项传递locallabelwidth给printbibliography。这样，当所有编号都固定时，所需的宽度测量将在本地执行（仅适用于此特定书目）。

% Print the labelnumber as the total number of entries in the
% current refsection, minus the actual labelnumber, plus one
\DeclareFieldFormat{labelnumber}{\mkbibdesc{#1}}
