Question

我正在尝试使用 table 环境中的 threeparttable 环境创建一个并排有三个子表的表，因为我想内置表格注释，并且我需要一个调整大小框。但是表格注释在表格中间被截断了。有没有办法使用 threeparttable 并创建两个、三个或更多子表和适当的表格注释，而无需在表格下手动创建文本？这是我的代码：

非常感谢您的建议。由于我使用的是 kpfonts，它稍小一些，因此我做了一些小改动后，成功使用了 leandriis 的示例 1。

以下是我的一些回答：

我试图实现的是将三个表格并排放置，并有一个标题和相同的表格注释。由于我是从 stata 生成结果，所以我希望有一个创建表格的自动化过程。我想使用，threeparttable因为我认为这是最简单、最快捷的方式来获得一个结构化的表格，并在表格中内置正确格式的表格注释等，而不必尝试不同的字体大小和表格下文本的位置。而且因为它对于我使用的页面来说太大了resizebox。

什么时候适合使用threeparttable？什么是\tnote指令？

Answer 1

据我所知，您没有threeparttable正确使用软件包的机制。当然，使用软件包时threeparttable，tablenotes环境应放在环境内部，而不是外部threeparttable。没有例外。

一个更根本的问题是，为什么要threeparttable首先为手头的材料使用环境？所有tabular环境都不包含任何\tnote指令。如果没有要处理的表格注释，为什么要设置tablenotes环境threeparttable？

以下是一些建议。

• 完全放弃threeparttable相关代码，集中精力使三个tabular环境更具可读性。无论你做什么：不要使用\resizebox指令随意将材料塞进（旋转的）文本块的宽度中。

• 相反，要专注于改善材料的整体组织或展示。通常的视觉提示对你有利。在下面的例子中，我选择使用三个subtable环境，每个表格环境一个，来为材料提供结构。

• 下面显示的三个表格采用了三种不同的“外观”。我更喜欢左侧和右侧的表格，但您可能更喜欢中间的表格。请注意，与代码中所做的相比，即使是中间的表格也更加精简。

• 该代码还使用了tabular*而不是tabular环境，以帮助消除有关列间空格宽度的猜测。

• 如果您的文档的主字体大小是12pt，则您应该在下面的代码中更改\small为。\footnotesize

Answer 2

以下是表格的五种不同版本：

在表格的第一个版本中，我刚刚删除了环境threeparttable。这会导致tablenotes扩展到所有三个表格的宽度。但是，我不推荐这种解决方案，因为它会保留resizebox并为您提供不一致且难以辨认的小字体大小，如以下屏幕截图所示：

---

在第二个示例中，我删除了resizebox并手动将字体大小减小到tiny。为了使表格更窄，我还减小了相邻列之间的水平空白。从以下屏幕截图中可以看出，字体比第一个示例中的字体稍大，但仍然太小（至少在我看来是这样）：

---

为了能够使用更大的字体，我在第三个示例中允许第二个和第三个表格之间有换行符。表格注释的宽度仍然与前两个表格的总宽度一样宽：

---

这是一个略有不同的变体，它将表注释放在第三个表旁边。在此示例中，我还\hline用包中的规则替换了您的命令和空行booktabs：

---

最后，您的表格也可以放入纵向页面，如以下屏幕截图所示。这里我使用了字体scriptsize和booktabs包：

---
