图形内部 tabularx 环境的水平对齐

Question

我正在制作一些图形，这些图形必须在环境中带有一些描述tabularx。我想将其tabularx与左边距对齐，但它仍然出现在中心。

我正在使用该ltablex包执行文档中的其他任务（例如\keepXColumns），但这个包似乎是导致我沮丧的原因。tabularx在这种情况下，我该如何使用这些包将环境左对齐？还有其他替代包吗？

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx,graphics}
\usepackage{ltablex}%<---This package

\begin{document}
\begin{figure}
\centering
\includegraphics[width=\linewidth]{example-image-a}\par
\footnotesize
\raggedright
\begin{tabularx}{\linewidth}{>{\bfseries}rX}
Description 1:&Some text\\
Description 2:&Some text\\
\end{tabularx}
\caption{This is a figure example}
\end{figure}

Answer 1

你走在正确的轨道上 :-) 你如何使用\keepXColumns？对我来说它很好用：

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx,graphics}
\usepackage{ltablex}%<---This package
\keepXColumns % <--- added

\begin{document}
\begin{figure}
\centering
\includegraphics[width=\linewidth]{example-image-a}\par

\footnotesize
\begin{tabularx}{\linewidth}{>{\bfseries}rX}
Description 1:&Some text\\
Description 2:&Some text\\
\end{tabularx}
\caption{This is a figure example}
\end{figure}

\begin{tabularx}{\linewidth}{>{\bfseries}rX}
Description 5:&Some text\\
Description 6:&Some text\\
\end{tabularx}
\end{document}
