表格文本适合页面宽度（表格适合但文本不适合）

Question

我想这是一个常见问题，我可以使用 tabularx 包将表格调整到适合文本宽度。但表格内的文本却放不进去。我想我忽略了一个小细节？感谢您的帮助。

以下是 MWE：

\documentclass[11pt,a4paper]{article}
\usepackage{verbatim}
\usepackage{tabu}
\usepackage{booktabs}
\usepackage{caption}
\usepackage{tabularx}

\begin{document}

\begin{table}[h!]
\small
\captionsetup{font=small}
\centering
\caption{Description of the features employed in this project.}
\label{table:1}
\begin{tabularx}{1.0\textwidth}{l||l}
\toprule
\textbf{Feature} & \textbf{Description}\\ \hline
Zero Crossing Rate & The rate of sign-changes of the signal during the duration of a particular frame. \\ \hline
Energy & The sum of squares of the signal values, normalized by the respective frame length. \\ \hline
Entropy of Energy & The entropy of sub-frames' normalized energies. It can be interpreted as a measure of abrupt changes. \\ \hline
Spectral Centroid & The center of gravity of the spectrum.\\ \hline
Spectral Spread & The second central moment of the spectrum.\\ \hline
Spectral Entropy & Entropy of the normalized spectral energies for a set of sub-frames.\\ \hline
Spectral Flux & The squared difference between the normalized magnitudes of the spectra of the two successive frames.\\ \hline
Spectral Rolloff & The frequency below which 90\% of the magnitude distribution of the spectrum is concentrated.\\ \hline
Mel-frequency coefficients (1-13) & Mel Frequency Cepstral Coefficients form a cepstral representation where the frequency bands are not linear but distributed according to the mel-scale.\\
\bottomrule
\end{tabularx}
\end{table}
\end{document}

Answer 1

至少有一列必须是环境X中的类型tabularx。

此外：

• tabu尽量避免；
• booktabs如果您使用或想要美观的表格，请避免使用垂直规则；
• 始终如一地使用规则：例如，booktabs不要\hline与混合；\toprule
• 永远不要将h其用作浮动的唯一放置选项：它的意思是“如果有空间，就在这里”，那么如果没有空间，LaTeX 应该怎么做？

代码：

\documentclass[11pt,a4paper]{article}
\usepackage{verbatim}
% \usepackage{tabu}% avoid like the plague
\usepackage{booktabs}
\usepackage{caption}
\usepackage{tabularx}

\begin{document}
\begin{table}[ht!]% never use h as the sole specifier
  \small
  \captionsetup{font=small}
  \centering
  \caption{Description of the features employed in this project.}
  \label{table:1}
  \begin{tabularx}{1.0\textwidth}{lX}% avoid vertical rules with booktabs
    \toprule
    \textbf{Feature} & \textbf{Description}\\ \midrule
