<p>🌲<strong>使用场景</strong>：<strong>因为表格可能很长,为了更好的表示表格的语义，可以将表格分割成 <code>表格头部</code>和<code>表格主体</code>两大部分.</strong></p> <p><strong>在表格标签中，分别用：<code><thead>标签</code> <code>表格的头部区域</code>、<code><tbody>标签</code> <code>表格的主体区域</code>. 这样可以更好的分清表格结构。</strong></p> <p>🌲<strong>总结:</strong><br> 1.<code> <thead></thead></code>：用于定义表格的头部。<code><thead></code> 内部必须拥有 <code><tr></code> 标签。 一般是位于第一行。<br> 2.<code> <tbody></tbody></code>：用于定义表格的主体，主要用于放数据本体 。<br> 3. 以上标签都是放在<code> <table></table></code> 标签中。</p> <h3><a name="t30"></a><a id="6_704"></a>（6）<a
