style=authoryear 在参考书目列表前面添加额外块

Question

这是我用来生成第一个参考书目的命令。但是我想要第二张图片的格式，即在参考文献前面有一个额外的块。文件可以在下面的 onedrive 链接中找到。

\documentclass{article}

\usepackage[citestyle=authoryear-comp,bibstyle=authortitle,sorting=nyt,dashed=false,%
    maxcitenames=1]{biblatex}

\newcounter{mymaxcitenames}
\AtBeginDocument{%
  \setcounter{mymaxcitenames}{\value{maxnames}}%
}

\renewbibmacro*{begentry}{%
  \printtext[brackets]{%
    \begingroup
    \defcounter{maxnames}{\value{mymaxcitenames}}%
    \printnames{labelname}%
    \setunit{\nameyeardelim}%
    \usebibmacro{cite:labelyear+extrayear}%
    \endgroup
    }%
  \quad% or \addspace
}

\DeclareNameAlias{sortname}{first-last}

\usepackage{filecontents}

\begin{filecontents}{biblatextest.bib}
@misc{A01,
  author = {Author, A. and Buthor, B.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}

\addbibresource{biblatextest.bib}

\begin{document}

Some text \autocite{A01}.

\printbibliography

\end{document}

现在命令以这种样式生成参考书目：

但我希望它像这样：

这个答案大量使用奥黛丽非常棒回答表格书目biblatex也锁住的在参考书目条目开头添加 [AuthorYear] 块的答案。

\printbibtabular除了我们只需要的定义

\newcounter{mymaxcitenames}
\AtBeginDocument{%
  \setcounter{mymaxcitenames}{\value{maxnames}}%
}

\newbibmacro*{bibcite}{%
  \defcounter{maxnames}{\value{mymaxcitenames}}%
    \iffieldundef{shorthand}
      {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
         {\usebibmacro{cite:label}%
          \setunit{\addspace}}
         {\printnames{labelname}%
          \setunit{\nameyeardelim}}%
       \usebibmacro{cite:labelyear+extrayear}}
      {\usebibmacro{cite:shorthand}}}

最后一段代码取自于authoryear.cbx，它将模拟这里的引用行为（我们没有从中获取代码，authoryear-comp以避免不必要的引用压缩，在某些情况下这会让我们只剩下年份）。

那么适当的bibtabular格式可以是

\defbibtabular{bibtabular}
  {\begin{tabular}{p{0.2\textwidth}p{0.8\textwidth}}}
  {\end{tabular}}
  {\usebibmacro{bibcite}}
  {}

\usepackage[citestyle=authoryear-comp, bibstyle=authortitle, sorting=nyt, dashed=false,%
    maxcitenames=1]{biblatex}


\DeclareNameAlias{sortname}{first-last}
