# 如何为表格添加标题？

你可以通过将其包裹在以下内容中来为表格添加标题 `tabular` 环境中放在一个 `表格` 环境：

```latex
\begin{table}
\caption{Your caption.}
\label{demo-table}
\begin{tabular}
...
\end{tabular}
\end{table}
```

下面的代码也使用了 `center` 环境，演示如何添加表格标题。它还使用了 `\label{demo-table}` 来创建一个用于引用该表格的标签（通过 `\ref{demo-table}`):

```latex
\documentclass{article}
\begin{document}
表格 \ref{demo-table} 有一个标题：
\begin{table}[!h]
\begin{center}
\caption{Your caption.}
\label{demo-table}
\begin{tabular}{||c c c c||}
 \\hline
 Col1 & Col2 & Col2 & Col3 \\ [0.5ex]
 \hline\hline
 1 & 6 & 87837 & 787 \\
 \\hline
 2 & 7 & 78 & 5415 \\
 \\hline
 3 & 545 & 778 & 7507 \\
 \\hline
 4 & 545 & 18744 & 7560 \\
 \\hline
 5 & 88 & 788 & 6344 \\ [1ex]
 \\hline
\end{tabular}
\end{center}
\end{table}
\end{document}
```

此示例会生成以下输出，表格居中显示在页面上：

![在 LaTeX 中为表格添加标题](/files/a3014e8507ce5d501f7e3a2798a4e9246046ac84)

请注意， `表格` 环境还会让表格“浮动”到 LaTeX 认为它应该放置的位置。这里，我们应用了 *浮动位置指定符* `!h` 将表格放置在“此处”，促使 LaTeX 将其放在文本行下方。如果你想对浮动位置有更多控制，可以使用更多指定符，如 [LaTeX Wikibook 的本节](http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions#Figures).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ayakaleaf-pro.ayaka.space/latex/zh-cn/wen-da/21-how-do-i-add-a-caption-to-a-table.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
