How to give if condition between ColumnProperty of datatable

I want to give if condition between datatable ColumnProperty. I tried but throwing syntax error. And from that I confused that how can I set if condition between ColumnProperty of datatable.

Here is my code,

@await Html.PartialAsync("Table", new DataTablesModel
{
   Name = "collection-grid",
   UrlRead = new DataUrl("CollectionList", "Customer",
             new RouteValueDictionary { [nameof(Model.CustomerCollectionSearchModel.CustomerID)] = Model.Id }),
   UrlDelete = new DataUrl("CollectionDelete", "Customer", null),
   Length = Model.CustomerCollectionSearchModel.PageSize,
   LengthMenu = Model.CustomerCollectionSearchModel.AvailablePageSizes,
   ColumnCollection = new List<ColumnProperty>
   {               
        new ColumnProperty(nameof(CustomerCollectionModel.CollectionName))
        {
            Title = T("Admin.Customer.Collection.Fields.CollectionName").Text,
            Width = "200"
        },
        if(Model.CustomerRoleNames == "Admin")
        {
            new ColumnProperty(nameof(CustomerCollectionModel.Id))
            {
                Title = T("Admin.Common.Delete").Text,
                Width = "100",
                Render = new RenderButtonRemove(T("Admin.Common.Delete").Text),
                ClassName = NopColumnClassDefaults.Button
            }
        }       
    }
})

Latest I used if condition in datatable but it showing red line error.

Is there any way to used if condition in datatable ColumnProperty?
