Answer 1

以下内容可能有助于您入门。我已删除所有出现的\raisebox、\textbf和\hline。相反，我从包中添加了几条水平线booktabs。

附注：表格下三分之一处的上标数字看起来像表格注释。如果是这样，您可能对该threepattable软件包感兴趣。我还建议使用通常的\label \ref机制，而不是手动引用表 3.1。

\documentclass{article}
\usepackage{booktabs}
\begin{document}

\begin{table}
    \caption{Fundamental Options of the Channel Setup Screen}
    \label{tab:PPer}

                             & Impact Hammer & Accelerometer  \\
    \midrule
    Physical Channel ID      & Input1        & Input2,...,16 \\
    On/Off                   & On            & On \\
