丰富的表格
- < table>为表格添加基础样式
- < thead>表格 表格行 的容器元素(< tr>)
- < tbody>表格主体的表格行的容器元素(< tr>)
- < tr>表格行
- < td>默认的表格单元格
- < th>特殊的表格单元格,(居中和加粗的效果)。必须在< thead>内使用
- < caption>关于表格存储内容的描述或总结
好看的类样式
- .table为任意< table>添加基本样式(只有横向分割线)
- .table-striped 在< tbody>内添加斑马线形式的条纹(IE8不支持),隔行变色
- .table-bordered为所有表格的单元格添加边框
- .table-hover在< tbody>内的任一行启用鼠标悬停状态,鼠标悬停高亮突出显示
- .table-condensed让表格更加紧凑
情景色类样式
适合应用在< th>、< tr> 、< td>
- table-active激活效果(悬停颜色)
- table-success表示成功或积极的动作
- table-info表示普通的提示信息或动作
- table-warning表示警告或需要用户注意
