我有一张需要编辑的表格。首先，我想用一条粗竖线将第一列与其余四列分开。其次，我想将“生物体 DNA 中碱基的百分比”排版在两行上。第三，“生物体”应位于三行中间 - 两行用于“生物体 DNA 中碱基的百分比”，一行用于包含“腺嘌呤”、“鸟嘌呤”、“胞嘧啶”和“胸腺嘧啶”的行。
为什么表格的左边缘有三个垂直条？为什么右边缘第二行缺少“||”？如果我想让第一列中的数据（不包括单词“Organism”）在左边缘对齐，我该如何修改代码？

答案1
您可以使用V{...}更粗的垂直线。

不设置\oddsidemargin，\evensidemargin并\topmargin；使用\calclayout，与 AMS 类。
将长标题分成两行并删除“Organism”下方规则的替代代码。
\begin{tabular}{|| c V{3} c | c | c | c||} \hline
\multicolumn{5}{|| c ||}{\textbf{Base Composition of DNA}} \\ \hline
Organism & \multicolumn{4}{ c ||}{%
\begin{tabular}{@{}c@{}}
Percentage of base\\
in organism's DNA
\end{tabular}%
} \\ \cline{2-5}

Maize & 26.8\% & 22.8\% & 23.2\% & 27.2\% \\ \hline

{\em E. coli} & 24.7\% & 26.0\% & 25.7\% & 23.6\% \\ \hline
\end{tabular}
您可以通过省略所有垂直线来轻松制作更好的表格；双重线和较粗的线毫无用处。此外，%在每个单元格中重复也是一种浪费，因为列已经声明包含百分比。
