标题周围的间距：文档类的作用

Question

我有一张如下表所写：

\begin{table}
    \centering
    \begin{tabular}{|l||c|c|}
    \hline&Column 1&Column 2\
        \hline\hline
    cell1 & cell2 & cell3 \\
    \hline
    cell1 & cell2 & cell3 \\\hline  
    \end{tabular}
    \caption{A test caption}
    \label{tab:attempt1}
\end{table}

现在标题非常靠近表格。另外，标题后面有一个很大的垂直空白...我该如何修复它，使其看起来像任何带有标题的普通表格？

只有表格才是这种情况，图形才能正常工作。

Answer 1

你可以尝试

\usepackage{caption} 
\captionsetup[table]{skip=10pt}

在你的序言中。另一方面，看看为什么表格标题应放在表格上方？

Answer 2

引起我注意的是另一个已发布在 TeX-LaTeX Meta 上。尽管这个问题已经问了将近六年，但——当然，恕我直言！——它仍然吸引着糟糕的答案，目前为止发布的所有答案中也没有令人满意的答案，包括此问题的前一个版本。这种说法可能听起来像是一种严厉的批评，显然需要充分的论证，我将在下面尝试提供；但我首先要明确一点，由于标题周围的间距可能取决于许多相互关联的因素（首先是文档类的选择），因此对问题的全面分析会让我们走得太远。在这个答案中，我选择专注于包如何caption帮助控制间距，并在必要时覆盖文档类做出的决定。

正如我所说的，这个答案是对以前明显不令人满意的版本的广泛修改，它或多或少对应于现在涵盖该类的caption包的使用的部分article。

标题周围的间距：文档类的作用

作为大卫·卡莱尔评论道问题发布几分钟后，其中描述的行为与标准类（article、report、books）的行为不一致；不久之后，Barbara Beeton 补充道当表格标题被amsart放置amsbook在amsproc以下表格本身，因为它们假设只有在figures 中标题才会出现在底部，而在tables（以及所有其他类型的浮动对象）中，标题都放在顶部。（例如，参见 ，amsart.cls第 1401-1408 行。）其他文档类也做出了类似的假设，因此，如果您坚持在底部为表格添加标题，就像标准类期望您做的那样，在使用这些类时，您将遇到类似的问题。llncs班级就是其中之一（参见llncs.cls，第 789–799 页和第 811–820 页）。我们选择仅展示amsart和 的行为article。

此代码发出一些诊断消息，帮助您验证我们将要提出的声明；出于同样的原因，它还绘制了标记浮动确切边界的细水平线，以使标题和浮动边缘之间不需要的垂直空间清晰可见。请注意，我们通过为其添加一些可拉伸性，使解决方案引入的垂直空间在诊断消息中清晰可辨。此外，您可以自己尝试不同的替代方案（例如llncs通过适当取消注释某些代码行（同时注释掉其他代码行），测试该解决方案对类的有效性。

很明显，可接受的答案不适用于该amsart类别；尽管如此，它可能会给人一种在该类别的情况下足够的印象llncs，但事实并非如此；事实上：

• 它会在标题和浮动边缘之间引入虚假空间；

• 尽管caption软件包在编译过程中发出了警告，但标题的外观是已更改并且与文档类指定的不同。

请注意，第二点不适用于该类amsart（因为它是包所知道的类之一）。llncs但是，对于该类，标题的外观不保留这一事实可能是一个问题，因此，人们可能更愿意完全避免使用该包。实际上，在这种情况下，如果坚持“从下方”为表添加标题，最简单的做法可能是恢复类中给出的两个环境和caption的原始定义（基于该类）。这可以通过取消注释以下行来实现tabletable*articlellncs

%\renewenvironment{table}
%  {\@float{table}}
%  {\end@float}
%\renewenvironment{table*}
%  {\@dblfloat{table}}
%  {\end@dblfloat}

在上面显示的代码中。由于我（再次）为 30000 个字符的限制而苦苦挣扎，我将让您自己检查我刚才所说的是否正确，以及尝试其他可能的替代方案，方法是适当地注释/取消注释该代码的各部分。毕竟，该类llncs不是标准发行版的一部分，我希望这个答案专注于与标准类一起使用的解决方案。但是，让我提请大家注意已接受答案的另一个缺点：它将标题和表格之间的跳过设置为忽略文档类所作设置的值。例如，该类amsart使用 12pt，而不是 10pt。

我发现@isk27 的回答和@agold 的有类似的缺陷：除了建议对每个浮动单独应用补丁外，它们还忽略了类预设的样式参数。center特别是环境，会产生太多空间。

使用caption包

实际上，只需加载该caption包即可解决问题：请参阅其手册第 2.6 节，从第 13 页开始。请注意，命令

\captionsetup[table]{skip=10pt}

指定标题和标题对象之间的跳跃值，仅当您想要更改文档类预设的值时才应使用它，正如已经指出的那样，这并不总是一个好主意。应该说，

\captionsetup[table]{position=above}

但在简单情况下不需要这样做，因为默认设置position=auto通常能够自动猜测标题出现的位置（浮动对象的上方或下方）。如果失败，除了上面显示的声明之外，您还可以在加载包时使用以下快捷方式，它也有效：

\usepackage[tableposition=above]{caption}

caption有关该包如何与某些已知文档类交互的信息，请参阅包手册的第 5 节。完整的可编译示例说明了它与article和amsart类的行为，还展示了如何覆盖特定表的常规设置，请参阅下一节。

表格用于调整标题周围垂直空间的策略caption有时会交换样式参数的含义\abovecaptionskip；\belowcaptionskip下一节中的所有示例都会打印这些参数的值，以帮助您了解包正在做什么。

article文档类

回想一下，使用 时article，如果你想要为表格添加标题“从多于”。

article+ caption，默认设置

在这种情况下，通常情况下，caption包足够智能，可以在所有情况下插入正确的空格，即使您包含一个与其他表格标题不同的特殊表格也是如此；但是，这并不能保证在所有情况下都有效。

\usepackage[T1]{fontenc} % I’m accustomed to always loading it...

amsart文档类

回想一下，使用 时amsart，如果你想要为表格添加标题“从以下”。

amsart+ caption，默认设置

对于amsart，默认设置意味着除figures 之外的所有浮点数（特别是所有tables）都应在上方标注标题。不幸的是，对于amsart包caption，无法正确处理以相反方式标注标题的异常表格。

\documentclass[a4paper]{amsart}
