我正在编写一个程序来将 wikimarkup 解析为 LaTeX，在创建表格时遇到了一点问题。由于某种原因，表格的右侧垂直边缘被推到了右边距，并且一些中心边框也重复了。
我尝试从最右边的单元格中删除文本，看看文本是否以某种方式推过边框，但似乎没有什么区别。我还尝试\textwidth手动设置为正确的值，但仍然没有成功。
这是完整的 LaTeX 代码：

与您的表格相比，以下是我实施的更改的一些亮点：
tabularx实现一种X列类型，该列类型会根据其他列和给定的宽度进行拉伸以填充表格中的剩余空间tabularx。使用它。\noindent阻止表格被推到右侧，因为它是段落中的第一个元素，这通常需要缩进。当然，如果您设置\parindent为0pt，这并不重要，但这只是一般建议。手动设置宽度的每列都必须精确计算，以适应边距。因此，每列由 2 条规则（宽度
\arrayrulewidth）、2 条列分隔/间隙（宽度\tabcolsep）以及物理列宽组成。因此，为了跨度\multicolumn为 2 列且两侧各有一条规则，请使用\multicolumn{2}{|p{\dimexpr0.5\linewidth-2\tabcolsep-2\arrayrulewidth}|}{...}
将会起作用，因为物理宽度（从一条规则到下一条规则）是0.5\linewidth。
在我的例子中，第二个\multicolumn不仅仅使用单个\arrayrulewidth。这是因为第一个\arrayrulewidth构成了第一个列集的一部分。- 使用\footnotesize而不是环境；在这种情况下，这不是必需的。
这geometry包中加载了showframe突出显示文本块边界的选项。
