如何限制长表中 \multicolumn 单元格的大小？

我在 LaTeX 中有一个非常长的表格，跨越多个页面，并且（就像现在一样）对于页面来说也太宽了。

我正在使用 longtable 包，其中每个列的宽度都由p{width}命令。

问题是，大多数行包含多列调用，因此不遵守前导码p{width}命令，导致表格总宽度过大。

最小的例子：

\begin{longtable}{|p{1in}|p{0.75in}|p{0.5in}|p{0.5in}|>{p{1in}|p{1in}|}
\caption{some cap} \label{somelable}\\
\hline
\multicolumn{2}{|c|}{\textbf{Text Header One}} & \multicolumn{2}{|c|}{\textbf{Text Header Two}} & \multirow{2}{*}{\textbf{Three}} & \multirow{2}{*}{\textbf{Four}} \tabularnewline \cline{1-4}
\textbf{Five} & \textbf{Six} & \textbf{Seven} & \textbf{Eight} &  & \tabularnewline \hline
Some Text String & Longer Text String Here & More Text Here & Text Example & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hlineExample Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & \multicolumn{2}{|l|}{Multi-column Text String that doesn't fit column width} & Text & Text \tabularnewline \hline
Example Text String Two & Longer Text String Example Two & width of box & text & Text & Text  \tabularnewline \hline
\end{longtable} 

我在序言中加载 longtable，并运行 pdflatex 几次（如 longtable 文档中所述）。它编译时有 0 个警告和 0 个错误。

如何获得正常的“窄”细胞？

你有没有尝试过使用|p{<sum of widths>}|对于格式选项\multicolumn?

这里只是猜测。
