使用 longtable 来显示图形：图形与水平线和垂直线重叠

我有大量的图表想要插入到 longtable 中来制作图表，可能长达几页。

但是，我无法缩放每个表格单元格内的图形，使它们不与表格中的水平线和垂直线重叠。如果我仅减小每个表格单元格的宽度，单元格和图形将缩小相同的倍数，而图形仍与线条重叠。

有人能帮助我更改代码以避免这种重叠吗？

此外，如何将“缺少图形”的文本水平和垂直地放置在单元格的中间？

提前致谢！

编辑：我无法在此窗口中正确格式化代码行。我使用 Ctr-K 和四个空格。如何正确执行此操作？

将此添加到您的序言中：

\usepackage{cellspace}
\setlength{\cellspacetoplimit}{3pt}
\setlength{\cellspacebottomlimit}{3pt}

并且 longtable 代码的第一行是

\begin{longtable}{|Sc|Sc|Sc|}

（如果您加载siunitx替换Sc为Cc）。
