<h3>Table 表格</h3>

<h4>常用于单表维护，通过属性配置实现简单的增、删、改、查、排序、过滤、搜索等常用功能，通过 <code>Template</code> 的高级用法能实现非常复杂的业务需求功能</h4>

<Block Title="自动生成搜索功能的表格" Introduction="当设置了 <code>ShowSearch</code> 时，如果未设置 <code>SearchTemplate</code> 编辑模板时，组件会尝试自动生成搜索条件 UI">
    <p>列信息绑定时通过设置 <code>Searchable</code> 属性，设置搜索条件自动构建 UI</p>
    <Tips>
        <p>自动构建搜索弹窗时，由于各列设置 <code>Searchable</code> 此时组件会通过 <code>SearchText</code> 与设置 <code>Searchable</code> 值为 <code>true</code> 的各列自动构建搜索拉姆达表达式，通过 <code>QueryPageOptions</code> 的属性 <code>Searchs</code> 获得</p>
