如何使用 pgfplotstable 修改 longtable 的布局

Question

为了编写一系列包含复杂长表的工业报告，我结合了在网站上找到的代码样本，这看起来很有希望。在我的领域，尽管通常推荐这种做法，但单元格需要用垂直线和水平线分隔。在 MWE（与实际需要相比非常简化）中，我仍然面临两个问题：数据行 1 和 2 之间没有水平线。此外，我无法在两列之间放置垂直线（以及其他要添加的垂直线）。我也欢迎任何改进代码（我不清楚在哪里最好地格式化列并定义每行之间的水平线）和/或视觉外观的提示。MWE 中的垂直线不是连续的。

Answer 1

让我们从问题的简单方面开始：

• 如果你喜欢使用垂直线，那么不要使用 中的规则\booktabs。相反，使用\hline

• 对于垂直线我建议执行以下操作：

  every odd column/.style ={% column type/.add={|}{} }, every even column/.style ={% column type/.add={|}{} }, every last column/.style ={% column type/.add={}{|} },

• 对我的口味来说，最好这样说every nth row={1}{before row=\hline}。表格下方的文字（下页继续）没有行。
