实现点击标头按所在列值进行排序，是一个非常有用的功能，其他的UI一般搞得非常复杂，添加标志图标什么的，使得本就不宽裕的表格更加拥挤。我的思路是，点击所在列的标头部位，传递标头值，然后根据标头值来改变查询语句。因为并不是所有列都需要排序，需要有一个特征字符。

以下是Table.razor

@typeparam T
<style>
    th {
        text-align: center;
        font-weight: 500;
        font-size: 16px;
        white-space: nowrap;
    }

    td {
        font-size: 14.66px;
        white-space: nowrap;
        overflow: hidden;
        text-overflow: ellipsis;
        line-height: 25px;
    }
</style>
<div>
    @ToolBarContent
</div>
<div>
    <table class="table table-bordered table-hover table-sm table-striped">
        <thead>
            <tr >
                @foreach (var item in HeaderTitles)
                {
                    if (IsSortabledColonum((string)item))
                    {
                        <th @onclick="()=>HeaderClick((string)item)" style="color:blue;cursor:pointer;">@HeaderTitle((string)item)</th>
                    }
                    else
                    {
                        <th>@item</th>
                    }

还是那个天气表格：

@page "/fetchdata"
@using MySoft.Data
@inject WeatherForecastService ForecastService

<PageTitle>Weather forecast</PageTitle>

<h1>Weather forecast</h1>

<p>This component demonstrates fetching data from a service.</p>

<Table @ref="myTable" HeaderTitles="headerTitles" T="WeatherForecast" OnHeaderClick="OnSort">
    <RowContent>
        <td>@context.Date.ToShortDateString()</td>

        <td>@context.TemperatureF</td>
        <td>@context.Summary</td>
    </RowContent>
</Table>

@code {
    private WeatherForecast[] forecasts = new WeatherForecast[] { };
    private YtTable<WeatherForecast>? myTable;
    private Array headerTitles = new string[]
    {
        "Date|","Temp. (C)","Temp. (F)","Summary|"
    };
    private bool dateSort, summarySort;
    protected override async Task OnInitializedAsync()
    {
        forecasts = await ForecastService.GetForecastAsync(DateOnly.FromDateTime(DateTime.Now));
    }
    private IQueryable<WeatherForecast> Query
    {
        get
        {
            if (myTable != null)
            {
                return myTable.Query;
            }
            return (new List<WeatherForecast>()).AsQueryable();
        }
        set
        {
            if (myTable != null)
            {
                myTable.Query = value;
            }
        }
    }
    protected override void OnAfterRender(bool firstRender)
    {
        base.OnAfterRender(firstRender);
        if (firstRender)
        {
            Query = forecasts.AsQueryable();
        }
    }
    private void OnSort(string title)
    {
        switch (title)

            case "Date":
                sortOnDate();
                break;
            case "Summary":

                break;
            default:
                break;
        }
    }
    private void sortOnDate()
    {
        dateSort = !dateSort;
        if (dateSort)
        {
            Query = Query.OrderBy(o => o.Date);
        }
        else
        {

    }

        else
