@page "/table"

<h3>Table</h3>

<table class="table">
    <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in items)
        {
            <tr>
                <td>@item.Id</td>
                <td>@item.Name</td>
            </tr>
        }
    </tbody>
</table>

@code {
    private List<Item> items = new List<Item>
    {
        new Item { Id = 1, Name = "Item 1" },
        new Item { Id = 2, Name = "Item 2" },
        new Item { Id = 3, Name = "Item 3" },
        new Item { Id = 4, Name = "Item 4" }
    };

    private bool showItem5 = true;

    protected override void OnInitialized()
    {
        if (showItem5)
        {
            items.Add(new Item { Id = 5, Name = "Item 5" });
        }
    }

    private class Item
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
}
