我是 LaTeX 新手，目前正在撰写硕士论文。我正在尝试使用该包创建两个相互堆叠的子表subcaption。
以下是代码：
The file was read into a dataframe and pivoted longer, using month, day and hour as indices, the grid points as `column` and the values as the `values` column. This turned a 8760 x 185 dataframe into a 1594320 x 5 dataframe, as shown in Table \ref{tab:ill_preproc}.
\begin{table}[h!]
\caption{Global caption}
\centering
\begin{subtable}[t]{0.5\linewidth}
\begin{tabular}{|c|c|c|c|c|c|c|}
\hline
Month & Day & Hour & Point 0 & Point 1 & Point ... & Point 182 \\ [0.5ex]
\hline
01 & 01 & 0.5 & ... & ... & ... & ... \\
01 & 01 & 1.5 & ... & ... & ... & ... \\
01 & 01 & 2.5 & ... & ... & ... & ... \\
01 & 01 & 3.5 & ... & ... & ... & ... \\
... & ... & ... & ... & ... & ... & ... \\
12 & 31 & 23.5 & ... & ... & ... & ... \\
\hline
\end{tabular}
\caption{Before pre-processing}
\label{tab:before_preproc}
\end{subtable}
\begin{subtable}[t]{0.5\linewidth} \centering
\begin{tabular}{|c|c|c|c|c|}
\hline
Month & Day & Hour & Point & Values\\ [0.5ex]
\hline
01 & 01 & 0.5 & 0 & ... \\
01 & 01 & 1.5 & 1 & ... \\
01 & 01 & 2.5 & 2 & ... \\
01 & 01 & 3.5 & 3 & ... \\
... & ... & ... & ... & ... \\
12 & 31 & 23.5 & 182 & ... \\
\hline
\end{tabular}
\caption{After pre-processing}
\label{tab:after_preproc}
\end{subtable}
\label{tab:my_label}
\end{table}
以下是我得到的结果：
现在，对于这个结果，有两点我不喜欢，并且想做出改变，其中有一点是“值得了解的”：
- 我该如何对齐子表，使每个子表的第一列不垂直对齐，而是子表相对于页面的垂直中心对称？为了更清楚起见，我希望第一个子表的“小时”列与第二个子表的“月份”列大致垂直对齐。
- 如何减少表格与上方文本之间的距离？
值得注意的是：有没有办法指定子表格与子标题之间以及子表格之间的垂直距离？
答案1
对于垂直对齐，请参见下面的答案；对于标题，请参见上面的评论
