我已经为下面的表格奋斗了 6 个小时，它慢慢地折磨着我。
几个问题：1）我不知道如何让线条垂直连续。2）我无法让它适合一页并且仍然可读（横向 A4）
任何帮助都太棒了！希望你们都很好！

我们可以看到，结果非常糟糕。您应该考虑将表分成两部分...
答案2
如果我正确理解了您的代码，您正在寻找排版一个 26 变量相关矩阵，或者至少是它的下对角线部分。对于每个非对角线元素，您愿意显示 3 位小数。这是直截了当的消息（您可能认为这很糟糕）：即使您设置了\tiny相对字体大小和非常小的列间空白（2*2pt 而不是默认的 2*6pt），您也需要（至少）纸张尺寸为“US Legal”（8.5"x14"）或 A3，以便在一张纸上排版整个矩阵。
不过，我们假设切换到 US-Legal 或 A3 纸张尺寸是不可行的。还能做什么呢？我建议只显示 2 位小数，而不是 3 位。（在下面的代码中S，siunitx以自动四舍五入到 2 位小数。）其次，列和行标题需要简化急剧地，只显示从 1 到 26 的数字。（当然，数字和变量名之间的对应关系应该在表格底部的图例中说明。）
通过这两项调整，可以通过设置来在单页上排版整个矩阵\scriptsize，字体大小线性减少30%。
