<h2>为什么表头样式如此重要</h2>
<p>在网页设计中,表格是组织和展示结构化数据的核心工具,而表头作为表格的"导航系统",扮演着至关重要的角色,精心设计的表头样式能显著提升用户体验:</p>
<ul>
<li>提高数据可读性和可扫描性</li>
<li>增强视觉层次和页面结构</li>
<li>帮助用户快速定位所需信息</li>
<li>提升网站专业度和可信度</li>
<li>响应式设计中的重要视觉锚点</li>
</ul>
<div class="tip-box">
<strong>专业建议:</strong> 根据研究,良好的表头设计可使数据理解速度提高40%,在财务、数据分析和电商类网站中尤其重要。

<h2>HTML表格基础结构</h2>
<p>在深入样式设置前,让我们回顾HTML表格的基本结构,表头使用<code><th></code>元素定义,通常位于<code><thead></code>内:</p>
<div class="code-block">
<table>
<thead>
<tr>
<th>产品名称</th>
<th>价格</th>
<th>库存</th>
<th>销量</th>
</tr>
</thead>
<tbody>
<tr>
<td>无线耳机</td>
<td>¥299</td>
<td>120</td>
<td>356</td>
</tr>
<!-- 更多行 -->
</tbody>
</table>
</div>
<p>通过CSS,我们可以为<code><th></code>元素添加各种样式,让表格既美观又实用。</p>
</section>
<section>
<h2>核心表头样式属性</h2>
<div class="properties-grid">
<div class="property-card">
<h4>背景与文字颜色</h4>
<p>使用<code>background-color</code>和<code>color</code>创建视觉对比</p>
</div>
<div class="property-card">
<h4>字体与文字属性</h4>
<p><code>font-weight</code>, <code>font-size</code>, <code>text-align</code> 等</p>
</div>
<div class="property-card">
<h4>内边距与边框</h4>
<p><code>padding</code>控制空间,<code>border</code>定义边界</p>
</div>
<div class="property-card">
<h4>悬停与交互效果</h4>
<p>使用<code>:hover</code>伪类增强用户体验</p>

<h2>表头样式实践示例</h2>
<h3>1. 基础表头样式</h3>
<p>创建清晰可辨的基础表头:</p>
<div class="code-block">
/* 基础表头样式 */
th {
background-color: #3a6bc9; /* 背景色 */
color: white; /* 文字颜色 */
font-weight: bold; /* 加粗字体 */
padding: 12px 15px; /* 内边距 */
text-align: left; /* 文本对齐 */
border-bottom: 2px solid #2a5298; /* 底部边框 */
}
</div>
<div class="table-container">
<table class="example-table">
<thead>
<tr>
<th>产品ID</th>
<th>产品名称</th>
<th>类别</th>
<th>价格</th>
</tr>
</thead>
<tbody>
<tr>
<td>P-1001</td>
<td>无线蓝牙耳机</td>
<td>电子产品</td>
<td>¥299</td>
</tr>
<tr>
<td>P-1002</td>
<td>机械键盘</td>
<td>电脑配件</td>
<td>¥450</td>
</tr>
<tr>
<td>P-1003</td>
<td>智能手表</td>
<td>穿戴设备</td>
<td>¥899</td>
</tr>
</tbody>
</table>
</div>
<h3>2. 渐变与高级效果</h3>
<p>使用CSS渐变和阴影增强视觉效果:</p>
<div class="code-block">
/* 渐变表头样式 */
th {
background: linear-gradient(to bottom, #4a6fc9, #2a5298);
color: white;
text-shadow: 0 1px 1px rgba(0,0,0,0.3);
padding: 14px 20px;
font-family: 'Segoe UI', Tahoma, sans-serif;
letter-spacing: 0.5px;
border: none;
box-shadow: 0 4px 6px rgba(0,0,0,0.1);
}
</div>
<div class="table-container">
<table class="example-table example-1">
<thead>
<tr>
<th>员工ID</th>
<th>姓名</th>
<th>部门</th>
<th>入职日期</th>
</tr>
</thead>
<tbody>
<tr>
<td>E-2105</td>
<td>张明</td>
<td>技术部</td>
<td>2022-03-15</td>
</tr>
<tr>
<td>E-2106</td>
<td>李华</td>
<td>市场部</td>
<td>2021-11-02</td>
</tr>
<tr>
<td>E-2107</td>
<td>王芳</td>
<td>人力资源</td>
<td>2020-08-24</td>
</tr>
</tbody>
</table>
</div>
<h3>3. 固定表头实现</h3>
<p>长表格中固定表头提升用户体验:</p>
<div class="code-block">
/* 固定表头样式 */
thead th {
position: sticky;
top: 0;
z-index: 10;
box-shadow: 0 2px 4px rgba(0,0,0,0.1);
}
/* 表格容器需要固定高度 */
.table-container {
height: 300px;
overflow-y: auto;
}
</div>
</section>
<section>
<h2>响应式表头设计</h2>
<p>在移动设备上,表格需要特别处理:</p>
<div class="code-block">
@media (max-width: 768px) {
/* 小屏设备表头调整 */
th {
padding: 10px 8px;
font-size: 0.9rem;
}
/* 水平滚动 */
.table-container {
overflow-x: auto;
}
/* 堆叠式表格 */
table.responsive-stack {
display: block;
}
table.responsive-stack thead {
display: none;
}
table.responsive-stack td {
display: block;
text-align: right;
}
table.responsive-stack td::before {
content: attr(data-label);
float: left;
font-weight: bold;
}
}
</div>
</section>
<section>
<h2>最佳实践与专业建议</h2>
<div class="tip-box">
<strong>专业提示:</strong> 表头颜色应与网站整体配色协调,但需要足够的对比度确保可读性,WCAG 2.0标准要求文本与背景的对比度至少达到4.5:1。
</div>
<ul>
<li>保持表头简洁明了,避免过多装饰</li>
<li>在大型表格中使用斑马纹(<code>tr:nth-child(even)</code>)提高可读性</li>
<li>为排序功能添加视觉指示器(如箭头图标)</li>
<li>测试不同设备和浏览器的显示效果</li>
<li>使用<code>scope="col"</code>或<code>scope="row"</code>属性提升可访问性</li>
</ul>

</div>
