如何让两列之间的差异变得更大？

在此处输入图片描述

我想使两列之间选定框的宽度更大。

\begin{table}[H]
  \centering
  \begin{tabularx}{\columnwidth}{@{}XXX@{}}
  \toprule
  \textbf{Parameter} & Description & Unit\\
  \toprule
\textbf{Task} & Total number of task in the system & numeric count\\
\textbf{VM} & Total number of VM in the system & numeric count\\
\textbf{Time} & Average required time to complete a task & milisec\\
\textbf{Utilization} & Resource utilization & \%\\
\textbf{VM's BW} & Bandwidth allocated for each VM & MB\\
\textbf{VM's CPU} & Number of CPU in a VM & Numeric Count\\
\textbf{Utilization Model} & CloudSim utilization model & Stochastic\\
 \bottomrule
  \end{tabularx}
  \caption{Difference performance metrics \label{tab:difMetrics}}
 \end{table}

列间空间不匹配是由于您使用的X列应该是l。

您可以像下面这样增加第二列和第三列之间的间距，但这只能治标不治本。

在下表中，您可以看到如何增加单个表的列间距（在环境中）；如果您希望全局增加，请\tabcolsep在序言中设置所需的宽度。即使对于当前的表，您也可能需要这样做。

\documentclass{article}
\usepackage{tabularx,booktabs}

\begin{document}

\begin{table}[htp]
\centering

\begin{tabularx}{\columnwidth}{@{}XX@{\hspace{2em}}X@{}}
\toprule
\textbf{Parameter} & Description & Unit\\
\toprule
\textbf{Task} & Total number of task in the system & numeric count\\
\textbf{VM} & Total number of VM in the system & numeric count\\
\textbf{Time} & Average required time to complete a task & milisec\\
\textbf{Utilization} & Resource utilization & \%\\
\textbf{VM's BW} & Bandwidth allocated for each VM & MB\\
\textbf{VM's CPU} & Number of CPU in a VM & Numeric Count\\
\textbf{Utilization Model} & CloudSim utilization model & Stochastic\\
\bottomrule
\end{tabularx}
