我只想排版通配符运算符表位于页面下方约 2/3 处。

我一直在工作，甚至不需要看起来好看。我应该使用什么工具？

我正在进行的工作

\documentclass{article}
\begin{document}
\begin{tabular*}{\linewidth}[t]{|l|l| }
\hline
\multicolumn{2}{|c|}{Wild-card Operators} \\ \hline
Character & Function \\ \hline

\_ (underscore) & matches any single character \\ \hline

\multicolumn{2}{|l|}{ \_am Frenc\_ matches Sam French, Tam Frenck, and Lam Frencq}         \\     \hline

\% & matches a string of one or more characters \\ \hline

\multicolumn{1}{|l|}{WHERE FirstName LIKE J\% matches any name starting with J} \\ \hline

$[]$  and \^ & Matches any char in specified range, \^ is negation op \\ \hline

\multicolumn{2}{|l|}{[a-g],[\^a-g],[bcdrf]} \\ \hline
\end{tabular*}
\end{document}

有一种可能性是：我用的是booktabs包中有更好看的表格（没有垂直规则），并且tabularx包以避免手动计算第二列的宽度；我还对代码部分使用了等宽字体（至\ttfamily和）：\texttt{}

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

\begin{document}

\noindent\begin{tabularx}{\linewidth}[t]{>{\ttfamily}lX}
\toprule
\multicolumn{2}{c}{Wild-card Operators} \\ 
\midrule
\rmfamily Character & Function \\ 
\cmidrule(r){1-1}\cmidrule(l){2-2}
\_ \rmfamily(underscore) 
  & matches any single character  \texttt{_am Frenc_} matches \texttt{Sam French}, \texttt{Tam Frenck}, and \texttt{Lam Frencq}  \\     
\% 
  & matches a string of one or more characters WHERE FirstName LIKE \texttt{J\%} matches any name starting with \texttt{J} \\
{[]}  \textrm{and} \^ & Matches any char in specified range, \texttt{\^} is negation op \texttt{[a-g]},\texttt{[\^{}a-g]},\texttt{[bcdrf]} \\
\bottomrule
\end{tabularx}

\end{document}
