我正在寻找一种允许两列的格式，并在页面中央有一个文本框；实际上是三个框。Wrapfig 无法完成这项工作，因为它只允许文本在一侧流动。

此解决方案使用 flowfram。flowfram 的优点是所有内容都相对于页面定位，而不是文本。
通常，当段落跨框架时，宽度不会改变。相反，您必须使用 手动拆分段落\nopar，并在需要时一次添加一个段落。
请注意，flowfram 与 twocolumn 不兼容，但可以使用更多流帧来伪造它。
\documentclass{article}
\usepackage[textwidth=6in]{geometry}
\usepackage{flowfram}
\usepackage{graphicx}
\usepackage{lipsum}% MWE only
\newcommand{\nopar}{\strut{\parfillskip=0pt\parskip=0pt\par}\framebreak\noindent}
\newflowframe[1,>2]{\dimexpr 0.5\textwidth-0.5\columnsep}{\textheight}%
{0pt}{0pt}% normal left column
\newflowframe[1,>2]{\dimexpr 0.5\textwidth-0.5\columnsep}{\textheight}%
{\dimexpr 0.5\textwidth+0.5\columnsep}{0pt}% normal right column
% the folowing wastes length registers, but is more easily read than using \dimen0 etc.
\newlength{\centerboxheight}
\newlength{\centerboxwidth}
\newlength{\boxsep}
\setlength{\centerboxheight}{2in}
\setlength{\centerboxwidth}{3in}
\setlength{\boxsep}{\intextsep}
\newflowframe[2]{\dimexpr 0.5\textwidth-0.5\columnsep}{\dimexpr 0.5\textheight-0.5\centerboxheight-\boxsep}%
{0pt}{\dimexpr 0.5\textheight+\centerboxheight/2+\boxsep}% upper left
\newflowframe[2]{\dimexpr 0.5\textwidth-0.5\centerboxwidth-\columnsep}{\dimexpr \centerboxheight+2\boxsep}%
{0pt}{\dimexpr 0.5\textheight-0.5\centerboxheight-\boxsep}% middle left
\newflowframe[2]{\dimexpr 0.5\textwidth-0.5\columnsep}{\dimexpr 0.5\textheight-0.5\centerboxheight-\boxsep}%
{0pt}{0pt}% lower left
\newflowframe[2]{\dimexpr 0.5\textwidth-0.5\columnsep}{\dimexpr 0.5\textheight-0.5\centerboxheight-\boxsep}%

{\dimexpr 0.5\textwidth+0.5\centerboxwidth+\columnsep}{\dimexpr 0.5\textheight-0.5\centerboxheight-\boxsep}% middle right
\newflowframe[2]{\dimexpr 0.5\textwidth-0.5\columnsep}{\dimexpr 0.5\textheight-0.5\centerboxheight-\boxsep}%
