我怎样才能在日期下方加上“初步”?

我怎样才能在日期下方加上“初步”?

我想在我的文档中添加“初步”。我尝试了以下可接受的答案: 在标题页中添加“非常初步”的提及 但我想把它放在日期下面。我该怎么做?(顺便问一下,它的常规位置在哪里?)

非常感谢!

其中,关键的是下面这个部分:

\begin{filecontents}{preliminary.sty}
\ProvidesPackage{preliminary}
\DeclareOption{draft}{%
  \AtBeginDocument{%
    \renewcommand\maketitlehookc{%
      \begin{center} \Large \textbf{ \color{red}{Preliminary}}\end{center}}}}
\ProcessOptions
\RequirePackage{titling}
\endinput
\end{filecontents}
\documentclass[12pt, draft]{article}
\usepackage{preliminary}

titling包裹提供了许多钩子:\maketitlehookc适合于\affilliation 和 之间\date,而 则\maketitlehookd遵循\date。因此,将您的 更改preliminary.sty为 update\maketitlehookd而不是\miketitlehookc

\begin{filecontents}[overwrite]{preliminary.sty}
\ProvidesPackage{preliminary}
\DeclareOption{draft}{%
  \AtBeginDocument{%
    \renewcommand\maketitlehookd{%
      \begin{center}
        \Large\bfseries\color{red}%
        Preliminary
      \end{center}}}}
\ProcessOptions
\RequirePackage{titling}
\endinput
\end{filecontents}
