这张表有 3 个问题。经过多次试验，我可以解决其中 1 或 2 个，但永远无法同时解决所有 3 个。我有一个非常挑剔的客户（他们不是都这样吗），我必须把这件事做好。
以下是代码：

以下是它的结果：
问题 1：我无法让 \hline 与桌子的边缘完全对齐。
问题 2：我需要文本（绿色链轮、彩绘木兰等）准确地从替代阴影的开始点开始，并且没有任何填充。
问题 3：在 Acrobat 上以 100% 的比例查看时，或者在 iPad 或 Android 设备上查看时，主要行之间的 \hline 不可见。
这是其屏幕截图。
当然，作为 LaTeX 的初学者，我可能完全做错了，也许有更好的方法来实现我的目标。
答案1
您的\hlines 没有对齐，因为后面有虚假空格
Type One & \adjustbox{valign=t}{
和类似的，你用一个开放的 来结束一行。这可以通过在末尾{添加一个来消除，例如%
Type One & \adjustbox{valign=t}{%
至于填充，你必须将其减少tabcolsep到零，这是在
\newcolumntype{D}{>{\hspace{-\tabcolsep}}p{0.43\linewidth-2\tabcolsep}} %Description
Acrobat 中不可见的线条是阅读器的问题。（例如，在 Acrobat 中，放大 75% 后，它们仍部分可见）实际打印文档时，您应该能看到所有这些线条。

另一个选择是使用 booktabs包来获得比更优雅的规则\hline。booktabs你的表格变成：
