如何将表格后的文本与表格起始的列对齐？

在表格的标题之后，我有几行文字，我希望它们与表格的起始位置对齐。

表格是居中对齐的，我怎样才能找到表格的起始列以便将文本行放在那里？

我可以推荐这个软件包threeparttable吗？我认为这应该正是您想要实现的。这样，表格注释就会粘在表格上，并且语义上编码良好。如果您将标题放在顶部（就像我总是对表格所做的那样），它会看起来更好。

\begin{document}
\begin{table}%[] place some limitations here, if you want to stop the floating.

\caption{Pin name and description} % set this in front of \toprule in order to get the notes closer to the table
\begin{tablenotes}[flushleft] % you may leave the default (no options) if you like. Like this it is left aligned as you asked for.
\item AI Analog input
\item AO Analog output
\item DI Digital input
\item DO Digital output
\item P Power
\item Note: Pin names beginning with a \# character denotes that the single is active low.

您也可以将此解决方案用于您的表格。我只是改用了，booktabs因为我认为它更易于阅读并且具有更好的垂直间距。您可以轻松地将原始 MWE 包装在这样的 中threeparttable。
