<h3>Table 表格在弹窗内使用</h3>

<h4>用于带层级关系的数据选择中</h4>

<DemoBlock Title="弹窗中数据联动" Introduction="点击工具栏中的选择按钮弹出对话框选择候选数据" Name="TableDialog">
    <p>本例中展示如果通过 <code>Modal</code> 组件与 <code>Table</code> 进行联动，通过弹窗中选择数据，然后再进行编辑</p>
    <ul class="ul-demo">
        <li>点击 <code>选择</code> 按钮弹出对话框选择产品 <code>Product</code></li>
        <li>弹窗中选择产品后点击 <code>确定</code> 按钮关闭弹窗</li>
        <li>点击 <code>编辑</code> 按钮，由于设置部分数据为只读，只能更改 <code>Count</code> 字段</li>
