如何在長表中強制將標題置於左側？

Question 1

像這樣？

\documentclass[12pt,a4paper]{article}
 \usepackage[left=2cm,right=2cm,top=2cm,bottom=4.5cm]{geometry}% simplified

\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[portuguese]{babel}
\usepackage[T1]{fontenc}
\usepackage{makecell,multirow,tabularx,booktabs}
\usepackage{longtable}
\usepackage{graphicx}
\usepackage{caption}
\captionsetup{labelfont=bf, singlelinecheck=false}% added, had to be here
\captionsetup[table]{singlelinecheck}% added for changing table caption

%this is for figure captions inside a multicolumn/longtable
\makeatletter
\def\figcaption{%
    \refstepcounter{figure}%
    \@dblarg{\@caption{figure}}
    }
\makeatother

\begin{document}
        %%%%%%%%%%%%%%%%%%START TABLE%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    \begin{longtable}{|p{2.5cm}p{2.5cm}p{2.5cm}p{2.5cm}p{2.5cm}p{2.5cm}|}

        \endfirsthead    
        \multicolumn{6}{r}{\textit{Continuação da página anterior}}\\ \hline
        \endhead    
        \hline
        \multicolumn{6}{r}{\textit{Continua na próxima página}}\\
        \endfoot
        \endlastfoot    
        \hline
        \multicolumn{6}{|l|}{\textbf{Resultado:}} \\
        %inicio da figura
        \multicolumn{6}{|l|}{
                \includegraphics[scale=0.4]{example-image-a}
               \figcaption{This caption should be on the flushleft and it is not}}
        \\ %fim da figura
        \multicolumn{6}{|l|}{} \\
        \hline
        \caption{Table A - test caption forced to the left}
    \end{longtable}
\end{document}

編輯： 對於標題，定義了兩種設置，一種用於所有標題，一種用於表格標題的寬度添加。 MWE的結果與之前相同。

Question 2

caption這個答案使用了和包的一些功能subcaption。由於可以進行一系列定制，因此它可以提供通用的解決方案。我也嘗試過使用該包的一些功能ltcaption，但最終這裡沒有實際實現。

為了簡單起見，我刪除了與格式化標題和副標題無關的程式碼。caption,ltcaption和包subcaption提供了各自的\captionsetup,\captionsetup[longtable]和\captionsetup[sub]宏，但正如已經提到的，最終我沒有使用\captionsetup[longtable].

這些人物被放置在subfigure實際的環境中minipages。使用subfigure環境是使用的要求\subcaption。然後，子標題將使用提供的格式\captionsetup[sub]。因為這指定了justification=raggedright子圖的標題設定在左邊距。使用該方法也將長表標題設置在左邊距captionsetup，但在這種情況下，更有可能要求標題與表格邊緣左對齊，因此我添加了這一點margin=1.75來實現這一點。最終的結果是它看起來接近要求。

也可以自訂標題的格式，以提供冒號作為標題和標題類型（在本例中為表格和子圖）之間的分隔符號。這些名稱也可以使用\DeclareCaptionLabelFormat巨集進行自訂。我為表格標題添加了標籤格式設置，用葡萄牙語編寫為 Tabela，對於子圖格式，我只使用了 Subfigure。發布的範例表明子圖具有阿拉伯編號，但我嘗試從阿拉伯字母重置編號的嘗試沒有成功。該範例還顯示了帶有 alpha 標籤的 longtable 標題，這是透過\renewcommand{\thetable}{\Alph{table}}.

結果是這樣的：

MWE如下：

\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[portuguese]{babel}
\usepackage[T1]{fontenc}
\usepackage{longtable,ltcaption,subcaption}

\captionsetup{labelformat=ltcapt,margin=1.75cm,labelsep=colon,justification=raggedright,singlelinecheck=off}
\renewcommand{\thetable}{\Alph{table}}
