具有固定寬度的兩列的表格

Question

我想建立一個具有固定寬度的兩個單元格，如下圖所示：

我使用了這段程式碼：

\begin{tabular}{c c}
\setlength\arraycolsep{10pt}

AVG & The average weight of a document is calculated as the sum of weights W(t,c) of its terms dithe document.  \\
STD & The standard deviation of the weighted as    of the snus the av\\
MIN & The minimum weight of a document is the l)  in the document.  \\
MAX & The  weight of a  term weight W(t,c) found  \\
PROB & The overall weight of a docuvided by the total number the docu \\
PROP & The between the number of vocabulary terms of the docume
\end{tabular}

但問題是，沒有邊框！

Answer 1

用這個：

\documentclass[twocolumn]{article}

\usepackage{tabularx, ragged2e, caption, lipsum}
\setlength{\extrarowheight}{2pt}

\begin{document}

\lipsum[1]
\begin{table}[!htb]
\caption{my caption} \label{some-label}% for cross references
\begin{tabularx}{\linewidth}{|l|>{\arraybackslash\RaggedRight}X|}
\hline

    MIN & The minimum weight of a document is the l) in the document. \\
