Question

如何在轴背景预操作中绘制的另一个填充区域之上的区域之间绘制填充？

\documentclass{article}

\usepackage{pgfplots, pgfplotstable}
\usepgfplotslibrary{groupplots}
\usepgfplotslibrary{fillbetween}
\usetikzlibrary{calc}
\usetikzlibrary{shapes,arrows}
\pgfplotsset{grid style={dashed}}

\begin{document}

\begin{tikzpicture}
    \begin{groupplot}[group style={group size=1 by 2}]
        \nextgroupplot[
            grid,
            axis background/.style={%
                preaction={
                    path picture={
                        \fill [black!5] (axis cs:2,0) rectangle (rel axis cs:1,1);
                    }
                }
            }
        ]
        \addplot[name path=path1] table {
            0 0
            1 1
            2 2
            3 3
            4 5
        };
        \addplot[name path=path2] table {
            0 1
            1 2
            2 3
            3 4
            4 6
        };
        \addplot[fill=red, forget plot, fill opacity=0.25] fill between[of=path1 and path2];

        \nextgroupplot[
            grid,
            axis background/.style={%
                preaction={

                    }
                }
            }
        ]
   \end{groupplot}
\end{tikzpicture}
