# 我該如何為表格新增標題？

你可以透過將以下內容包在其中，為表格加上標題 `tabular` 環境包在一個 `表格` 環境：

```latex
\begin{table}
\caption{你的標題。}
\label{demo-table}
\begin{tabular}
...
\end{tabular}
\end{table}
```

以下程式碼也使用了 `center` 環境，示範如何加入表格標題。它也使用了 `\label{demo-table}` 來建立一個標籤，以便在引用表格時使用（透過 `\ref{demo-table}`):

```latex
\documentclass{article}
\begin{document}
表格 \ref{demo-table} 的標題為：
\begin{table}[!h]
\begin{center}
\caption{你的標題。}
\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}
```

此範例會產生以下輸出，表格置中於頁面：

![在 LaTeX 的表格中加入表格標題](/files/f9114f7e9e2dfb02d4a8b337415e60e889e3da68)

請注意， `表格` 環境也會讓表格「浮動」到 LaTeX 認為它應該出現的位置。這裡我們套用了 *浮動位置指定符* `!h` ，將表格放在「這裡」，以促使 LaTeX 將其置於文字行下方。如果你想更精確地控制浮動位置，可以使用其他指定符，如 [LaTeX Wikibook 的這一節中所述](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://overleaf-pro.ayaka.space/latex/zh-tw/wen-yu-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.
