按行项目条件更改 MudBlazor 表背景颜色

我正在尝试更改 mudblazor 表中一行的颜色。问题是，我无法添加根据行元素的条件更改颜色的功能。

 <MudTable Items="@context.orderPositions" Context="AddressContext" Hover="true" Breakpoint="Breakpoint.Sm" Elevation="0" Style="background-color: @(AddressContext.OrderPositionStatus == PositionStatus.rdy ? yellowgreen : blue;">

You can:

<MudTable Items="@Items" Hover="true" RowStyleFunc="RowStyleFunc">

And then

private string RowStyleFunc(Item arg1, int index)
{
    switch (arg1.Title)
    {
        case string a when a.Contains("1/4"):
            return "background-color:blue";
        case string b when b.Contains("2/4"):
            return "background-color:red";          
        default: return "background-color:white";

    }
}
