Center a table's caption using apa6 with man mode

Question

There are several questions that are related, yet not quite the answer to this question:

1. Centering tables in document class apa6
2. How do force center-alignment in a caption in a figure?

The questions are only relevant when the apa6 document is in the doc mode.

This post is seeking advice on using centered caption in man mode.

For example, in doc mode, everything works fine:

\documentclass[apacite,noextraspace]{apa6} 

\usepackage[utf8x]{inputenc} 
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{amsmath} 
\usepackage{amscd} 
\usepackage{float} 
\usepackage{geometry}
\usepackage{paralist}
\usepackage{wrapfig}
\usepackage{framed}
\usepackage{amsfonts}
\usepackage{setspace}

\captionsetup{singlelinecheck=on,justification=centering}
\shorttitle{test}
\geometry{left=1.in,right=1.in,top=1.in,bottom=1.in} 
\begin{document}
\begin{table}[!ht]
\begin{center}
\caption{Matrix of Questions} 
\label{tab:one}
\begin{tabular}{cccc}
  \hline
  & \multicolumn{3}{c}{Header }\\
  \cline{2-4}
 Left Column & $\phi$ & $\rho$ & $\theta$ \\ 
  \hline
1 & 2 & 3 & 4 \\
5 & 6 & 7 & 8 \\
9 & 10 & 11 & 12 \\
13 & 14 & 15 & 16 \\
   \hline
\end{tabular}
\end{center}
\end{table}

\end{document}

However, the same code but in man mode, added only man to documentclass, the results are poor:

\documentclass[man,apacite,noextraspace]{apa6} 

\usepackage[utf8x]{inputenc} 
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{amsmath} 
\usepackage{amscd} 
\usepackage{float} 
\usepackage{geometry}
\usepackage{paralist}
\usepackage{wrapfig}
\usepackage{framed}
\usepackage{amsfonts}
\usepackage{setspace}

\captionsetup{singlelinecheck=on,justification=centering}
\shorttitle{test}
\geometry{left=1.in,right=1.in,top=1.in,bottom=1.in} 
\begin{document}
\begin{table}[!ht]
\begin{center}
\caption{Matrix of Questions} 
\label{tab:one}
\begin{tabular}{cccc}
  \hline
  & \multicolumn{3}{c}{Header }\\
  \cline{2-4}
 Left Column & $\phi$ & $\rho$ & $\theta$ \\ 
  \hline
1 & 2 & 3 & 4 \\
5 & 6 & 7 & 8 \\
9 & 10 & 11 & 12 \\
13 & 14 & 15 & 16 \\
   \hline
\end{tabular}
\end{center}
\end{table}

\end{document}

Is there a way to change this?

If not, is there a way to align the table label (e.g. "Table 1") to the left?

Answer 1

You also need the following line in your preamble

\DeclareCaptionTextFormat{tabletext}{\hspace{-\parindent}\textit{#1}}

This is the same definition used for doc mode.

MWE:

\documentclass[man,apacite,noextraspace]{apa6}

\usepackage[utf8x]{inputenc}
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{amsmath}
\usepackage{amscd}
\usepackage{float}
\usepackage{geometry}
\usepackage{paralist}
\usepackage{wrapfig}
\usepackage{framed}
\usepackage{amsfonts}
\usepackage{setspace}

\DeclareCaptionTextFormat{tabletext}{\hspace{-\parindent}\textit{#1}}
\captionsetup{singlelinecheck=on,justification=centering}

\shorttitle{test}
\geometry{left=1.in,right=1.in,top=1.in,bottom=1.in}
\begin{document}
\begin{table}[!ht]
\centering
\caption{Matrix of Questions}
\label{tab:one}
\begin{tabular}{cccc}
  \hline
  & \multicolumn{3}{c}{Header }\\
  \cline{2-4}
 Left Column & $\phi$ & $\rho$ & $\theta$ \\
  \hline
1 & 2 & 3 & 4 \\
5 & 6 & 7 & 8 \\
9 & 10 & 11 & 12 \\
13 & 14 & 15 & 16 \\
   \hline
\end{tabular}
\end{table}

\end{document}
