使用 tcbposter 将页面分成独立的列

Question

我得到了一个非常好的答案这个问题（如何将页面分成 2 列）但新的障碍来了。现在我需要将其分成 1 列）和 3 列。到目前为止（感谢伊格纳西）我有以下文件：

使用以下代码：

\documentclass[a4paper]{article}
\usepackage[most]{tcolorbox}
\usepackage{lmodern}
\usepackage{lipsum}
\usepackage{geometry}
\usepackage{pdfpages}
\pagestyle{empty}
\begin{document}
\begin{tcbposter}[%
    coverage = spread,
    poster = {columns=5, rows=1, spacing=-.5mm},
    boxes={sharp corners, colback=white}
]
\posterbox[left=12mm, enhanced, 
          overlay={\fill[black!70] (frame.north west) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=90]{Lorem ipsum dolor sit amet} 
          ([xshift=9mm]frame.south west);} 
]{name=left, column=1, span=3, rowspan=1}{\lipsum[1-2]}
\posterbox[right=12mm, enhanced, 
          overlay={\fill[black!70] (frame.north east) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=270]{Lorem ipsum dolor sit amet} 
          ([xshift=-9mm]frame.south east);} 
]{name=right, column=4, span=2, rowspan=1}{\lipsum[1]}
\end{tcbposter}
\end{document}

我现在想做的是获得以下内容：

1）单列：

2）树形等列（在这张图片上它们看起来并不相等，但这是因为我只是在 Paint 上绘制它们）

我玩弄这段代码很长时间，但只得到了一个错误，没有得到预期的结果。有人能帮我吗？提前谢谢！

这是一个依靠奇怪的（手动计算的）值将海报移动到正确位置的尝试：

\documentclass[a4paper]{article}
\usepackage[most]{tcolorbox}
\usepackage{lmodern}
\usepackage{lipsum}
\usepackage{geometry}
\usepackage{pdfpages}
\pagestyle{empty}
\begin{document}
\begin{tcbposter}[%
    coverage = spread,
    poster = {columns=5, rows=1, spacing=-.5mm},
    boxes={sharp corners, colback=white}
]
\posterbox[left=12mm, enhanced, 
          overlay={\fill[black!70] (frame.north west) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=90]{Lorem ipsum dolor sit amet} 
          ([xshift=9mm]frame.south west);} 
]{name=left, column=1, span=3, rowspan=1}{\lipsum[1-2]}
\posterbox[right=12mm, enhanced, 
          overlay={\fill[black!70] (frame.north east) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=270]{Lorem ipsum dolor sit amet} 
          ([xshift=-9mm]frame.south east);} 
]{name=right, column=4, span=2, rowspan=1}{\lipsum[1]}
\end{tcbposter}
\begin{tcbposter}[%
    coverage = {spread, left=12.5mm},
    poster = {columns=3, rows=1, spacing=-.5mm, width=\dimexpr\linewidth-9.5mm},
    boxes={sharp corners, colback=white}
]
\posterbox[enhanced,
          overlay={\fill[black!70] (frame.north west) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=90]{Lorem ipsum dolor sit amet} 
          ([xshift=-9mm]frame.south west);} 
]{name=left, column=1, rowspan=1}{\lipsum[1-2]}
\posterbox{name=center, column=2, rowspan=1}{\lipsum[1]}
\posterbox[enhanced,
          overlay={\fill[black!70] (frame.north east) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=270]{Lorem ipsum dolor sit amet} 
          ([xshift=9mm]frame.south east);} 
]{name=right, column=3, rowspan=1}{\lipsum[1]}
\end{tcbposter}
\end{document}

更新：我以为你会通过摆弄选项键来获得单列的东西，但这里有一个代码示例：

\begin{tcbposter}[%
    coverage = spread,
    poster = {columns=1, rows=1, spacing=-.5mm},
    boxes={sharp corners, colback=white}
]
\posterbox[left=12mm, right=12mm, enhanced, 
          overlay={
          \fill[black!70] (frame.north west) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=90]{Lorem ipsum dolor sit amet} 
          ([xshift=9mm]frame.south west);
          \fill[black!70] (frame.north east) rectangle 
          node[font=\sffamily\bfseries,text=white,rotate=270]{Lorem ipsum dolor sit amet} 
          ([xshift=-9mm]frame.south east);} 
]{name=left, column=1, rowspan=1}{\lipsum[1-2]}
\end{tcbposter}
