\begin{center}
\begin{tabularx}{\textwidth}{|Y|Y|l|}
\hline
Name&Frequency Range&Interpretation and Appearance\\ \hline\hline
Delta \delta&0.1 - 3.5 Hz&Deep sleep or unconsciousness.\\
Theta \theta&4 - 7.5 Hz&Decreased consciousness or sleep.\\
Alpha \alpha&8 - 13 Hz&Awake, relaxed, (clinically: awake or eyes closed)\\
Beta \beta  &14 - 30 Hz&Consciously alert, agitated, or tense\\

Answer 1

我提出了两种实现方式，在这两种方式中我都使用了siunitx改善措施外观的设施。

\documentclass{article}
\usepackage{geometry} % wider text

\usepackage{siunitx}
\usepackage{tabularx} % for the first instance
\usepackage{booktabs} % for the second instance

\begin{document}

\begin{table}

\begin{tabularx}{\textwidth}{
  |>{\centering}X|
  >{\centering}X|
  l|
}
\hline
Name           & Frequency Range            & Interpretation and Appearance\\
\hline\hline
Delta $\delta$ & \SIrange{0.1}{3.5}{\hertz} & Deep sleep or unconsciousness.\\
Theta $\theta$ & \SIrange{4}{7.5}{\hertz}   & Decreased consciousness or sleep.\\
Alpha $\alpha$ & \SIrange{8}{13}{\hertz}    & Awake, relaxed, (clinically: awake or eyes closed)\\
Beta  $\beta$  & \SIrange{14}{30}{\hertz}   & Consciously alert, agitated, or tense\\
Gamma $\gamma$ & \SI{>30}{\hertz}           & Attention, sensory stimulation\\
\hline
\end{tabularx}

以下是表格的两个版本：

\documentclass{article}

\usepackage{tabularx}
\newcolumntype{Y}{>{\centering\arraybackslash}X}

%%%%% Only for the second example %%%%%
\usepackage{booktabs}
\usepackage{calc}
\usepackage{siunitx}
\newlength{\mycolwidth}
\setlength{\mycolwidth}{\widthof{Range in \si{\hertz}}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
