HTML表格标题，说白了，就是用
标签给表格加个说明，让大家一眼就知道这表格是干嘛的。这玩意儿挺重要的，尤其是在内容比较复杂或者表格比较多的页面上，能大大提升用户体验。
| 姓名 | 语文 | 数学 | 英语 |
|---|---|---|---|
| 张三 | 80 | 90 | 85 |
| 李四 | 75 | 85 | 92 |
这样，表格上方就会显示一个“学生成绩表”的标题了。
标签和标签的<a style="color:#f60; text-decoration:underline;" title="区别" href="https://www.php.cn/zt/27988.html" target="_blank">区别</a>？
有些人可能会把
标签和
</pre>标签搞混。<pre class="brush:php;toolbar:false;"><title></pre>标签是定义整个HTML文档的标题，显示在<a style="color:#f60; text-decoration:underline;" title="浏览器" href="https://www.php.cn/zt/16180.html" target="_blank">浏览器</a>的标题栏或者标签页上，而<pre class="brush:php;toolbar:false;"><caption></pre>标签是定义表格的标题，只在表格内部显示。</p> <p>简单来说，<pre class="brush:php;toolbar:false;"><title></pre>是给整个网页起名字，<pre class="brush:php;toolbar:false;"><caption></pre>是给表格起名字。</p> <p><span>立即学习</span>“<a href="https://pan.quark.cn/s/cb6835dc7db1" style="text-decoration: underline !important; color: blue; font-weight:

class="brush:php;toolbar:false;"><caption></pre>标签会在表格上方居中显示。但有时候，你可能需要把它放在表格下方，或者修改它的字体、颜色等等。这时候，就可以用CSS来控制。</p> <p>比如，要让<pre class="brush:php;toolbar:false;"><caption></pre>标签显示在表格下方，可以用<pre class="brush:php;toolbar:false;">caption-side</pre>属性：</p><div class="aritcle_card flexRow"> <div class="artcardd flexRow"> <a class="aritcle_card_img" href="/xiazai/code/9756" title="企业建站系统2.0"><img

class="brush:php;toolbar:false;"><caption></pre>标签显示在表格下方，字体大小为1.2em，颜色为深灰色，并且左对齐。</p> <h3>不用<caption>标签，用其他标签代替行不行？</caption> </h3> <p>理论上是可以的，比如用<pre class="brush:php;toolbar:false;"><h1></pre>到<pre class="brush:php;toolbar:false;"><h6></pre>或者<pre class="brush:php;toolbar:false;"><p></pre>标签，然后用CSS来模拟<pre class="brush:php;toolbar:false;"><caption></pre>标签的效果。但是，强烈不建议这样做。</p> <p><pre class="brush:php;toolbar:false;"><caption></pre>标签的语义化更好，它明确地告诉浏览器和<a style="color:#f60; text-decoration:underline;" title="搜索引擎" href="https://www.php.cn/zt/20588.html" target="_blank">搜索引擎</a>，这个标签是用来描述表格的。这对于SEO和可访问性都有好处。而且，<pre class="brush:php;toolbar:false;"><caption></pre>标签有一些默认的样式和行为，比如默认显示在表格上方居中，用其他的标签来模拟，需要自己写更多的CSS代码。</p> <p>所以，除非你有特殊的需求，否则还是老老实实用<pre
