如何使用 threeparttable 更改表格注释

Question

请参阅下文，了解我使用的代码及其生成的表格。我如何更改表格下方的文本（即注释），使其不严格位于表格下方，而是延伸得更多？它最多可以是两行，而现在由于表格下方居中，它需要 4 行...

    \begin{table}
       \centering
        \begin{threeparttable}
        \caption{standardised factor loadings for the 5-item models for Motivation}
        \label{cross5items}
            \begin{tabular}{c c c c c}
            \toprule 
            & time 0  & time 1 & time 3 & time 4 \\
            \midrule
            $\lambda_1$     & 0.678 & 0.692 & 0.688 & 0.685  \\
            $\lambda_3$     & 0.499 & 0.516 & 0.610 & 0.573     \\
            $\lambda_4$     & 0.730 & 0.775 & 0.697 & 0.744     \\
            $\lambda_5$     & 0.442 & 0.510 & 0.506 & 0.655       \\
            $\lambda_6$     & 0.876 & 0.781 & 0.856 & 0.828\\
            \bottomrule  
            \end{tabular} 
                \begin{tablenotes}
                \small
            \item   $\lambda_k$ is the standardised factor loading of item $k$, with the standard error in brackets. All factor loadings were highly significant: $p_{MLR}$ and $p_{MLE}$ <.001.

                \end{tablenotes}

        \end{threeparttable}
    \end{table}

Answer 1

如果您不需要（或不想！）将tabular环境下方的图例限制在 的宽度内tabular，您可以将图例放在环境之外threeparttable，或者完全摆脱threeparttable机械。

\documentclass{article}
\usepackage{amsmath,booktabs,ragged2e}
\usepackage[flushleft]{threeparttable}
\begin{document}

%% first, the original table
\begin{table}
\centering
\begin{threeparttable}[ht]
\caption{with \texttt{threeparttable}}
\label{tab:a}
\begin{tabular}{@{} ccccc @{}}
    \toprule 
    & time 0  & time 1 & time 3 & time 4 \\
    \midrule
    $\lambda_1$ & 0.678 & 0.692 & 0.688 & 0.685  \\
    $\lambda_3$ & 0.499 & 0.516 & 0.610 & 0.573  \\
    $\lambda_4$ & 0.730 & 0.775 & 0.697 & 0.744  \\
    $\lambda_5$ & 0.442 & 0.510 & 0.506 & 0.655  \\
    $\lambda_6$ & 0.876 & 0.781 & 0.856 & 0.828  \\
    \bottomrule  
\end{tabular} 
\begin{tablenotes}
\small
\item[]$\lambda_k$ is the standardised factor loading of item $k$, 
with the standard error in brackets. All factor loadings were highly 
significant: $p_{\textrm{MLR}}$ and $p_{\textrm{MLE}} <.001$.
\end{tablenotes}
\end{threeparttable}
\end{table}

%% next, a solution without a 'tablenotes' environment.
\begin{table}
\centering
\begin{threeparttable}[ht]
\caption{without \texttt{tablenotes}}
\label{tab:b}
\begin{tabular}{@{} ccccc @{}}
    \toprule 
    & time 0  & time 1 & time 3 & time 4 \\
    \midrule
    $\lambda_1$ & 0.678 & 0.692 & 0.688 & 0.685  \\
    $\lambda_3$ & 0.499 & 0.516 & 0.610 & 0.573  \\
    $\lambda_4$ & 0.730 & 0.775 & 0.697 & 0.744  \\
    $\lambda_5$ & 0.442 & 0.510 & 0.506 & 0.655  \\
    $\lambda_6$ & 0.876 & 0.781 & 0.856 & 0.828  \\
    \bottomrule  
\end{tabular} 
\end{threeparttable}% important to leave a blank line next:

\noindent
$\lambda_k$ is the standardised factor loading of item $k$, with the 
standard error in brackets. All factor loadings were highly significant: 
$p_{\textrm{MLR}}$ and $p_{\textrm{MLE}} <.001$.
\end{table}

%% finally, a solution that doesn't employ any part of the `threeparttable` machinery
\begin{table}[h]
\centering
% \smallskip % optional
\caption{without \texttt{threeparttable}}
\label{tab:c}
\begin{tabular}{@{} ccccc @{}}
    \toprule 
    & time 0  & time 1 & time 3 & time 4 \\
    \midrule
    $\lambda_1$ & 0.678 & 0.692 & 0.688 & 0.685  \\
    $\lambda_3$ & 0.499 & 0.516 & 0.610 & 0.573  \\
    $\lambda_4$ & 0.730 & 0.775 & 0.697 & 0.744  \\
    $\lambda_5$ & 0.442 & 0.510 & 0.506 & 0.655  \\
    $\lambda_6$ & 0.876 & 0.781 & 0.856 & 0.828  \\
    \bottomrule  
\end{tabular} 

\smallskip
\justifying
\small
\noindent
$\lambda_k$ is the standardised factor loading of item $k$, with the 
standard error in brackets. All factor loadings were highly significant: 
$p_{\textrm{MLR}}$ and $p_{\textrm{MLE}}<.001$.
