##2, bootstrap-table

Basic Example

<table class="table"></table>

Striped table

Using the .table-striped class, you can add a zebra stripe style to each row within .

The striped table is implemented by relying on the :nth-child CSS selector, and this feature is not supported by Internet Explorer 8.

Bordered table

Add the .table-bordered class to add borders to the table and each cell within it.

Mouseover

You can make each row in respond to the mouseover state by adding the .table-hover class.

Condensed table

By adding the .table-condensed class, the table can be made more compact, and the padding in the cells will be halved.

状态类

通过这些状态类可以为行或单元格设置颜色。

Class 描述

.active        鼠标悬停在行或单元格上时所设置的颜色.success    标识成功或积极的动作.info        标识普通的提示信息或动作.warning    标识警告或需要用户注意.danger        标识危险或潜在的带来负面影响的动作

响应式表格

将任何 .table 元素包裹在 .table-responsive 元素内，即可创建响应式表格，其会在小屏幕设备上（小于768px）水平滚动。当屏幕大于 768px 宽度时，水平滚动条消失。

<div class="table-responsive">
      <table class="table">
     ...
      </table>
</div>

3、bootstrap表单

基本实例

单独的表单控件会被自动赋予一些全局样式。所有设置了 .form-control类的 <input>、<textarea></textarea> 和 <select></select> 元素都将被默认设置宽度属性为 width: 100%;。 将 label 元素和前面提到的控件包裹在 .form-group中可以获得最好的排列。

<form role="form">告诉辅助设备（如屏幕阅读器）这个元素所扮演的角色是个表单</form><form role="button">告诉设备，这是个按钮，可以点击。本质上是增强语义性，增强组件的可访问性、可用性</form>

不要将表单组合输入框组混合使用，建议将输入框组嵌套到表单组中使用。

<form>
      <div class="form-group">
            <label for="exampleInputEmail1">Email address</label>
             <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email">
       </div>
       <div class="form-group">
             <label for="exampleInputPassword1">Password</label>
             <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
        </div>
       <div class="form-group">
          <label for="exampleInputFile">File input</label>
             <input type="file" id="exampleInputFile">
           <p class="help-block">Example block-level help text here.</p>
     </div>
       <div class="checkbox">
             <label>
               <input type="checkbox"> Check me out
             </label>
      </div>
       <button type="submit" class="btn btn-default">Submit</button>
</form>

多个控件可以排列在同一行:

<form class="form-inline">
      <div class="form-group">
            <label for="exampleInputName2">Name</label>
            <input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe">
      </div>
      <div class="form-group">
            <label for="exampleInputEmail2">Email</label>
            <input type="email" class="form-control" id="exampleInputEmail2" placeholder="jane.doe@example.com">
      </div>
     <button type="submit" class="btn btn-default">Send invitation</button>
</form>

水平排列的表单

通过为表单添加 .form-horizontal 类，并联合使用 Bootstrap 预置的栅格类，可以将 label 标签和控件组水平并排布局。这样做将改变 .form-group 的行为，使其表现为栅格系统中的行（row），因此就无需再额外添加 .row 了。

单选和多选框

多选框（checkbox）用于选择列表中的一个或多个选项，而单选框（radio）用于从多个选项中只选择一个。

设置了disabled属性的单选或多选框都能被赋予合适的样式。对于和多选或单选框联合使用的 标签，如果也希望将悬停于上方的鼠标设置为“禁止点击”的样式，请将 .disabled 类赋予 .radio、.radio-inline、.checkbox、.checkbox-inline 或 <fieldset>。</fieldset>

多选框：

<div class="checkbox">      <label>          <input type="checkbox" value="">
        Option one is this and that—be sure to include why it&#39;s great       </label></div>
<div class="checkbox disabled">      <label><input type="checkbox" value="" disabled>
            Option two is disabled      </label></div>

单选框：

<div class="radio">
      <label>
            <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
        Option two can be something else and selecting it will deselect option one
      </label>
</div>
<div class="radio disabled">
      <label>
            <input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
            Option three is disabled
      </label>
</div>

通过将 .checkbox-inline 或 .radio-inline 类应用到一系列的多选框（checkbox）或单选框（radio）控件上，可以使这些控件排列在一行。
