让桌子看起来更美观

Question

我有一张包含以下代码的表格：

Table \ref{tab:2} lists all the variables in the model:
\begin{table}[htbp]
\caption{Variable Descriptions}
\label{tab:2}
\begin{center}
\begin{tabular}{|c|c|}\hline
Variables & Descriptions\\\hline
\textit{ln(wage)} & log of wage\\
\textit{educ} & years of education\\
\textit{black} & 1 if black and 0 if not\\
\textit{hisp} & 1 if hispanic and 0 if not\\
\textit{exper} & years of experience\\
\textit{exper$^{2}$} & years of experience squared\\
\textit{married} & 1 if married and 0 if not\\
\textit{union} & 1 if belongs to a union and 0 if not\\\hline
\end{tabular}
\end{center}
\end{table}

我想知道是否可以有一张更漂亮、更专业的桌子。

booktabs建议。请参阅手册以了解更多提示。

\documentclass{article}
\usepackage{array,booktabs}
\begin{document}
  Table \ref{tab:2} lists all the variables in the model.

  \begin{table}
    \caption{Variable Descriptions}
    \label{tab:2}
    \centering
      \begin{tabular}{>{\itshape}ll}
        \toprule
        \upshape Variables & Descriptions\\\midrule
        ln(wage) & log of wage\\
        educ & years of education\\
        black & 1 if black and 0 if not\\
        hisp & 1 if hispanic and 0 if not\\
        exper & years of experience\\
        exper$^{2$} & years of experience squared\\
        married & 1 if married and 0 if not\\
        union & 1 if belongs to a union and 0 if not\\\bottomrule
      \end{tabular}
  \end{table}
\end{document}

如果您希望表格内联，如其前面的冒号所示，则根本不要使用。您可以使用包或类似包table获取标题。caption
