长桌笔记

Question

有人能帮我在下面的长表格中添加表格注释吗？我希望表格注释位于表格底线下方，并将所有信息保存在一页上。注释想添加：报告与伴侣同居的人被归类为已婚。第三，就业状况由三类组成：就业、失业和非劳动力。学生和退休人员构成非劳动力类别。最后，家庭规模衡量受访者家庭中的家庭成员数量，其中包括受访者（及其配偶和/或子女）本人。

longtable我宁愿使用包longtblr。tabularray表代码更简单，您可以将注释（和备注）添加为表选项（请参阅下面的 MWE）。有关更多详细信息，请tabularray参阅包文档。但是编译时间稍长：

如您所见，我对表体的外观进行了一点改动。如果您不喜欢，可以在表序中删除行

                          row{2-Z} = {rowsep = 0pt},
                      row{even[4]} = {abovesep=1ex},

Answer 2

添加注释列表的一种方法longtable是在合并的单元格内添加列表。

在示例中，自定义环境TabNotes用于封闭注释的格式并简化所有必要的更改（如果需要）。我还添加了一个\TN用于在单元格中创建注释的宏。

您可以考虑使用两个不同的标题来指示后续页面上同一个表格的延续。它需要在环境\caption内部longtable，而不是外部。附加宏\header是为了避免重复相同的长标题两次。

Answer 3

根据您提供的信息，我制作了这个示例。如您所见，我删除了几乎所有注释行并添加了两个包：

1. graphicx提供\rotatebox{angle}{text}选项 - 用于旋转列标题和
2. geometry更灵活地定义论文的尺寸

最终的代码如下：

\documentclass[11pt]{article}

\usepackage{threeparttable}     % can be replaces by the package threeparttablex for additional options
\usepackage{longtable}
\usepackage{multirow,dcolumn}
\usepackage{booktabs}

\usepackage{color}
\usepackage{subcaption}
    \captionsetup[table]{position=top,skip=6pt}

\usepackage{siunitx}

\usepackage{graphicx}   % provied \rotatebox{angle}{text}

\usepackage[
    paper=letterpaper,
    margin={12mm,15mm},
    ]{geometry}     % adds flexibilty to define margins and paper dimensions

\newcommand\thead[1]{\rotatebox{90}{\begin{tabular}{@{}c@{}}#1\end{tabular}}}

笔记：旋转标题可以节省表格布局中的空间，并使其更易于阅读。因此，横向甚至longtable不再需要。
