razor代码：

C#获取select数据源代码

页面首次加载时，切换下拉框的选项不生效，需要第二次才能生效；如果不添加空值，则可以正常切换选项

@Idle-wang 下载包提示有病毒

我不知道为什么会提示病毒，我用的公司电脑打包上传的，不过代码很简单
在模板中，首先将实体类中Name改为下拉框呈现
[Required(ErrorMessage = "{0}不能为空")]
[AutoGenerateColumn(Order = 10, Filterable = true, Searchable = true ,ComponentType=typeof(Select))]
[Display(Name = "姓名")]
public string? Name { get; set; }
然后再设置下拉框的数据源
`<Table TItem="Foo" AutoGenerateColumns="true" class="table-demo"
IsPagination="true" PageItemsSource="PageItemsSource"
IsStriped="true" IsBordered="true"IsMultipleSelect="true"
ShowSkeleton="true" ShowToolbar="true" ShowSearch="true" ShowExtendButtons="true"
OnQueryAsync="OnQueryAsync" OnSaveAsync="OnSaveAsync" OnDeleteAsync="OnDeleteAsync">

<TableColumn @bind-Field="@context.Name" Items="GetNames(context)" />
<TableColumn @bind-Field="@context.Hobby" Items="GetHobbys(context)" />

private IEnumerable GetNames(Foo item) => new[] { new SelectedItem ("", "請選擇..."), new SelectedItem ("Beijing", "北京"), new SelectedItem ("Shanghai", "上海"), }; `
