页面末尾的 Paracols 内的颜色框

页面末尾的 Paracols 内的颜色框

我目前正在实现一个动态 PDF 创建器。因此我需要将 paracol 环境的最后两列始终放在页面的末尾（底部）。有什么方法可以实现这一点吗？

它看起来应该是这样的（带有黑色边框的灰色块是敏感信息）： 在此处输入图片描述

但灰色块应该位于页面末尾，并应从下到上“增长”。

目前状态（静态内容）：

您对如何使用 paracols 解决这个问题有什么想法吗？

编辑 主要问题：如何动态填充文本（“好处”之后）和灰色框之间的区域。这样，灰色框就会始终位于页面底部。\vfill所有类似的解决方案都不起作用。

答案1

最后我使用以下解决方案代替 paracol：

\newtcbox{\bottomBox}[1][]{%
  width=85mm,
  boxsep=0pt,
  top=3mm,left=3mm,right=3mm,bottom=3mm,
  arc=0pt,auto outer arc,
  colback=lightgray,colframe=lightgray,
  boxrule=0mm,box align=base,on line,
  #1, enhanced,attach boxed title to top left={xshift=-2mm},
  boxed title style={size=small,colframe=white!0,colback=white!0,},
  coltitle=red,fonttitle=\bfseries
}

\newcommand{\productBottom}[4]{
  \par\vbox{}\null\vfill\nopagebreak

  \begin{tcbraster}[raster columns=2,raster equal height,
                    nobeforeafter,raster column skip=6mm]
    \bottomBox[title={\fontsize{9,5}{14}\selectfont #1}]{
        \textbf{\fontsize{9,5}{14}\selectfont #2}
    }
    \bottomBox[title={\fontsize{9,5}{14}\selectfont #3}]{
        \textbf{\fontsize{9,5}{14}\selectfont #4}
    }
  \end{tcbraster}
}

并在文档中像这样使用它：

\productBottom
  {Test Title Left}
    {Test Text Left}
  {Test Title Right}
    {Test Text Right}
