我尝试并排创建两个表格，但在 PDF 中它们似乎没有对齐。第二个表格比第一个表格略低，我不知道如何修复它。
如有任何建议，我们将不胜感激。

尝试这个：
\documentclass{article}
\usepackage{tabularx}
\usepackage{multicol}
\begin{document}
\begin{table}[ht]
\begin{minipage}[b]{0.5\linewidth}%\centering
\begin{tabular}{|c|c|c|c|}
\hline
& One & Twp & Three \\
\hline
1 & Subject A: & Subject A & Subject \\
2 & Subject B & Subject B& Subject \\
3 & Subject C & Subject C & Subject \\
4 & Subject D & Subject D & Subject \\
4 & Subject E & Subject E & Subject \\
5 &Subject F & Subject F & Subject \\
6 & Subject G & Subject G & Subject \\
7 &Subject H &Subject H &Subject \\
\hline
\end{tabular}
\caption{Table 1}
\end{minipage}
\hspace{0.5cm}
\begin{minipage}[b]{0.5\linewidth}
\centering
\begin{tabular}{|c|c|c|c|}
\hline
& One & Twp & Three \\
\hline
1 & Subject A: & Subject A & Subject \\
2 & Subject B & Subject B& Subject \\
3 & Subject C & Subject C & Subject \\
4 & Subject D & Subject D & Subject \\
4 & Subject E & Subject E & Subject \\

\end{table}
\end{document}
答案2
问题：
您的表格超出了文本宽度，因为您使用了 2 倍加
0.5\linewidth。\hspace{0.5cm}这可能会导致对齐问题，并且通常会带来问题。您使用 将小页面对齐到底部
[b]，而不是顶部。我猜是因为标题，但这样您就无法控制顶部了。
我建议：
始终注意行宽和文本宽度。注意：小页面之间的换行符或空白也算数，需要留出空间。
%在行尾前插入可防止这种情况发生。使用可选的高度参数 或
minipage。\parbox您可以使用固定高度、顶部对齐（下方pos、inner-pos），或许\vfill可以实现顶部和底部对齐（标题）。句法：
\begin{minipage}[pos][height][inner-pos]{width}进一步提示：垂直线确实会分散注意力。对我来说，一些水平线通常没问题。我强烈建议使用
booktabs包装。只要看看好书，你就会发现精美的表格不会用垂直线打断行。

这不是您问题的一部分，但我认为如果您遵循文档中给出的建议booktabs，您可以制作出更好看的表格。比较一下。
