當 tabuarray 有分頁符號時如何獲得關閉的框架？

Question

我用 tabularray 建立了一個框架表，如果整個表位於一頁上，它看起來很好。

當表格中有分頁符號時，就會出現開放角落。

當使用 rowhead 和 rowfoot 時，開放角會消失，但這會增加額外的行（或多或少是一個不同的表），在使用表的所有情況下我都不希望這樣做。

當 tabularray 有分頁符號時，如何獲得關閉的框架？

\documentclass[11pt, a4paper]{article}
\usepackage[top=5mm, bottom=15mm, includehead]{geometry}
\usepackage{tabularray}

\begin{document}

\vspace*{200mm}

\begin{longtblr}[]{
        width=0.8\textwidth,
        rows={3em, m, rowsep=2pt},
        colspec = {X[c] X[c] X[c] X[c]},
        hlines = {leftpos = 0, rightpos = 0},
        hline{1} = {1}{-}{leftpos = 1, rightpos = 1},
        hline{1} = {2}{-}{leftpos = 0, rightpos = 0},
        hline{Z} = {1}{-}{leftpos = 0, rightpos = 0},
        hline{Z} = {2}{-}{leftpos = 1, rightpos = 1},
        vlines,
        vline{1} = {1}{-}{ abovepos = 1, belowpos = 1},
        vline{1} = {2}{-}{ abovepos = 0, belowpos = 0},
        vline{Z} = {1}{-}{ abovepos = 0, belowpos = 0},
        vline{Z} = {2}{-}{ abovepos = 1, belowpos = 1},
        %rowhead = 1, rowfoot = 1
    }
    Alpha &      &       &       \\
          & Beta &       &       \\
          &      & Gamma &       \\
          &      &       & Delta \\
\end{longtblr}

\end{document}

解決方案並不遙遠。感謝邁克爾的幫助！

使用 rowhead 和 rowfoot 分配高度 0 + 拉伸 = 0。要開心。

    ...
    \begin{longtblr}[]{
        width=0.8\textwidth,
        rows={3em, m, rowsep=2pt},
        colspec = {X[c] X[c] X[c] X[c]},
        hlines = {leftpos = 0, rightpos = 0},
        hline{1} = {1}{-}{leftpos = 1, rightpos = 1},
        hline{1} = {2}{-}{leftpos = 0, rightpos = 0},
        hline{Z} = {1}{-}{leftpos = 0, rightpos = 0},
        hline{Z} = {2}{-}{leftpos = 1, rightpos = 1},
        vlines,
        vline{1} = {1}{-}{ abovepos = 1, belowpos = 1},
        vline{1} = {2}{-}{ abovepos = 0, belowpos = 0},
        vline{Z} = {1}{-}{ abovepos = 0, belowpos = 0},
        vline{Z} = {2}{-}{ abovepos = 1, belowpos = 1},
        row{1}={ht=0pt, rowsep=0pt},
        row{Z}={ht=0pt, rowsep=0pt},
        rowhead = 1,
        rowfoot = 1,
        stretch = 0,
      }
