两个并排的 tblr 子表，以及它们下方的第三个 tblr 子表

Question

我有 3tblr个子表（在table环境中），我想将前 2tblr个子表放在一个旁边，将第三tblr个子表放在前两个子表下。我该怎么做？（请参阅下面的代码）。

我不知道您使用的文档类，但您可以尝试使用subcaptionblocks。在下面的 MWE 中，我尽可能地保留了您的 MWE，只将文档类更改为article并加载了enumitem您使用的包\setlist，我认为这是必要的。

labelfont=bf我在加载包时使用了选项subcaption，以粗体显示子标题的标签。请注意，在 中subcaptionblock，您应该使用\caption而不是 ，\subcaption但前者被解释为您使用了后者。

• 我没有您的文档类。相反，我使用article，但我很确定建议的解决方案也适用于您的。
• 如我所见，您所显示的表格很短，可以放在一页上，因此它们可以轻松适应table*环境（跨越文档中的两列），因此无需从两列切换到一列并转回。
• 您应该知道，table*插入文本后它将出现在下一页的顶部。
• 如果您估计它可以位于插入它的同一页面的底部，那么您可以使用包来强制它stfloats（正如我在下面的 MWE 中所做的那样）。
• 对于子表，我将使用包subfloat提供的环境subfig，或者更确切地说，使用包版本 3.1 或更新版本提供的模拟subcaption。使用它的表代码会短一些。
• 我将用 分隔前两个子表\hfill，对于第三个子表，您只需要在它之前插入空行（并最终添加一些垂直跳过（例如\bigskip）以便更好地形成表格：

您确定需要所有已加载的包来编写表格吗？其中大多数都可以轻松地用tabularray包替换...

（红线表示页面布局）

Answer 3

我可能已经找到了一个解决方案，通过使用以下结构，由@Guido Muscioni 在“在子图环境中对齐图形和表格“（并在两个顶部子表之间使用自定义的水平空间，如“如何在乳胶中两个图形之间添加额外的水平间距？"，在这里我使用\hspace{0.05\textwidth}而不是\hfill)。

基本思想是使用这种结构：

\begin{table}\centering
\subfloat[legend]{\label{A}}\hfill
\subfloat[legend]{\label{B}}\par 
\subfloat[legend]{\label{C}}
\caption{my table}
\end{table}

然后tblr在里面添加\subfloat，如下所示（只是 MWE）：

\begin{table}\centering
\subfloat[legend]{\label{A}\begin{tblr}{}Feature & A & B & C\\\end{tblr}}\hfill
\subfloat[legend]{\label{B}\begin{tblr}{}Feature & A & B & C\\\end{tblr}}\par 
\subfloat[legend]{\label{C}\begin{tblr}{}Feature & A & B & C\\\end{tblr}}
\caption{my table}
\end{table}

所以，回到我最初的帖子，这是最终的结果：

Answer 4

我不知道wlscirep_modified，但我猜测所提出的解决方案也适用于它。

1. 不需要技巧来获得一列输出，只需使用table*

2. 使用单独的subtable环境

这是代码，虽然我不明白为什么要使用tblr。我添加了一个技巧，可以容纳不在页面中的浮动。

\documentclass[twocolumn,fleqn,10pt,dvipsnames,table]{wlscirep}

\usepackage[T1]{fontenc}
\usepackage{caption}
\usepackage{subcaption}
\usepackage{tabularray}

\usepackage{lipsum}% for context

\renewcommand\dblfloatpagefraction{0.7}% usual value 0.5
