Xltabular，跨多个页面的threeparttable

Question

我似乎无法让表格延伸到下一页，并且“--继续上一页”位于第二页的顶部。

有人能帮我按照多列代码将这个长表格放到多个页面上并具有固定宽度的列吗？

谢谢，艾德

对于横向表格，请将pdflscape包添加到您的序言中，并将整个ThreePartTable环境放置在环境内landscape。表格的宽度会自动调整到可用空间。

由于 overleaf 使用的是旧版本的xltabular，因此第二页的标题将显示错误的数字。为了解决这个问题，您可以添加\addtocounter{table}{-1}以下示例所示的内容。使用最新安装和最新版本的xltabular，此行不再是必需的：

\documentclass{article}

Answer 2

只要尊重 的语法就足够了threeparttablex，它并不完全是 的语法threeparttable：

• 环境是ThreePartTable（3个大写字母）；
• 表格注释如下已声明在TableNotesThreePartTable 的最开始处，然后使用命令将其插入到 longtable（或 xltabular）中\insertTableNotes。在下面的代码中，我将其插入到表格的最末尾，即部分中\endlastfoot。

话虽如此，我不明白为什么要声明固定宽度的列，这些列在每个单元格中，系统地使用\multicolumn{1}{m{some length}}{...}。

无论如何，这里有一个有效的代码：

\documentclass{article}
\usepackage{xltabular}
\usepackage{dcolumn}
\usepackage{threeparttablex}
\usepackage{booktabs, caption}
\newcolumntype{C}{>{\centering\arraybackslash}X}
\newcolumntype{b}{>{\centering\arraybackslash}X}

附录：如果您想要 3 个标准 X 列和宽度小 3 倍的第 4 个 X 列，则必须使用表格序言中的语法：

 *{3}{>{\hsize=1.2\hsize}X}>{\hsize=0.4\hsize}X

（即，系数必须与相对列宽成比例，并且它们的总和必须等于 X 列的数量）。
