LaTeX でタイトル、日付、著者を左揃えにするにはどうすればいいですか?

LaTeX ドキュメントのタイトル、著者、日付を左揃えにしたいのですが、別のタイトル ページがありません。試してみました\author{\begin{flushleft}My name\end{flushleft}}が、うまくいきません。

パッケージを使用してそれを実行できますtitling:

\documentclass[11pt]{article}
\usepackage{titling}
\setlength{\droptitle}{-8ex}
\pretitle{\begin{flushleft}\Large\bfseries}
\posttitle{\par\end{flushleft}}
\preauthor{\begin{flushleft}\Large}
\postauthor{\end{flushleft}}
\predate{\begin{flushleft}}
\postdate{\end{flushleft}}
\title{What the Tortoise Said to Achilles}
\author{Charles Lutwige Dodgson}
\date{1895}

\begin{document}

\maketitle

Achilles had overtaken the Tortoise, and had seated himself comfortably on its back.

"So you've got to the end of our race-course?" said the Tortoise. "Even though it does consist of an infinite series of distances? I thought some wiseacre or other had proved that the thing couldn't be done?"

"It can be done," said Achilles. "It has been done! Solvitur ambulando. You see the distances were constantly diminishing; and so — "

"But if they had been constantly increasing?" the Tortoise interrupted. "How then?"

"Then I shouldn't be here," Achilles modestly replied; "and you would have got several times round the world, by this time!"

"You flatter me — flatten, I mean," said the Tortoise; "for you are a heavy weight, and no mistake! Well now, would you like to hear of a race-course, that most people fancy they can get to the end of in two or three steps, while it really consists of an infinite number of distances, each one longer than the previous one?"

"Very much indeed!" said the Grecian warrior, as he drew from his helmet (few Grecian warriors possessed pockets in those days) an enormous note-book and a pencil. "Proceed! And speak slowly, please! Short-hand isn't invented yet!"

"That beautiful First Proposition of Euclid!" the Tortoise murmured dreamily. "You admire Euclid?"

著者のデータに使用される で、の代わりにとの代わりに\@maketitleを使用するようにパッチを適用できます。著者が複数いる場合は、 にもパッチを適用する必要があります。flushleftcenter@{}l@{}ctabular\and

\documentclass{article}
\usepackage{xpatch}

\makeatletter
% title is flush left instead of centered
\xpatchcmd{\@maketitle}
  {center}
  {flushleft}
  {}{}
\xpatchcmd{\@maketitle}
  {center}
  {flushleft}
  {}{}
% author is flush left
\xpatchcmd{\@maketitle}
  {{c}}
  {{@{}l@{}}}
  {}{}
\xpatchcmd{\and}
  {{c}}
  {{@{}l@{}}}
  {}{}
\makeatother

\title{Title of the paper}
\author{Jenni \\ Some University \\ Somewhere}
\date{38 July, 2057}

\begin{document}

\maketitle

\section{Flush left title}

The title is flush left, isn't it?

\end{document}

\author複数の部分がある場合の出力は次のとおりです。

\author{Jenni \\ Some University \\ Somewhere \and Jinny \\ Other University \\ Otherplace}

これはうまくいくと思います:

\documentclass{article}
\usepackage[utf8]{inputenc}

\title{align title article}
\author{john doe}
\date{November 2020}

\makeatletter
\def\@maketitle{%
\begingroup
\setlength{\parindent}{0pt}
  \newpage
  \null
  \vskip 2em%
 % \begin{center}%
  \let \footnote \thanks
    {\LARGE \@title \par}%
    \vskip 1.5em%
    {\large
      \lineskip .5em%
      \begin{tabular}[t]{@{}c}%
    \@author
      \end{tabular}\par}%
    \vskip 1em%
    {\large \@date}%
  %\end{center}%
  \par
  \endgroup
  \vskip 1.5em}
  
\makeatother


\begin{document}
