我想自动生成报告。我使用 python 替换 LaTeX 模板中的占位符。报告包含跨多页的大型复杂表格。我找到了一个数据包cals https://groups.google.com/forum/#!topic/comp.text.tex/gE80AAOQ83U稍加修改即可支持行间分页符。
我现在的问题是，如果一个单元格的内容跨越两页以上，就会出现一个分页符，但实际上应该有两个分页符。有什么办法可以解决这个问题吗？
这是我的示例代码：
\documentclass{article}
\usepackage{lipsum}
\usepackage{cals}
\usepackage[latin]{babel}
\usepackage{blindtext}
\showboxbreadth=100
\showboxdepth=100
\makeatletter
\let\oldDispatch=\cals@row@dispatch
\newbox\rowBefore
\newbox\rowAfter
\newbox\decorationCopy
\newdimen\splitHeight
\def\cals@row@dispatch{%
\cals@ifbreak\iftrue % detect that a break is required
\splitHeight=\pagegoal \advance\splitHeight -\pagetotal
\ifdim \splitHeight>50pt % break inrow only if at least 100pt left
\advance\splitHeight -5pt % avoid pagebreak due to overflows
%
% Split the current row on two: before and after the break
%
\setbox\rowBefore=\hbox{}
\setbox\rowAfter=\hbox{}
\def\next{%
\setbox0=\lastbox
\ifvoid0
\def\next{\global\setbox\rowBefore=\box\rowBefore
\global\setbox\rowAfter=\box\rowAfter }%
\else
\setbox2=\vsplit0 to\splitHeight
\ifvoid0
\setbox0=\copy2
\fi
\setbox\rowBefore=\hbox{\box2 \unhbox\rowBefore}%
\setbox\rowAfter=\hbox{\box0 \unhbox\rowAfter}%
\fi
\next}
\setbox0=\hbox{\unhbox\cals@current@row \next}
%
% Decoration backup, typeset the first row,
% restore context, typeset the second at the end of macro
%
\setbox\decorationCopy=\copy\cals@current@cs
\setbox\cals@current@row=\box\rowBefore
\ht\cals@current@cs=\ht\cals@current@row
\oldDispatch
\cals@issue@break
\cals@thead@tokens
\setbox\cals@current@row=\box\rowAfter
\cals@reheight@cells\cals@current@row
\setbox\cals@current@cs=\box\decorationCopy
\ht\cals@current@cs=\ht\cals@current@row
\let\cals@current@context=b
\fi
\fi
