Kendo如何将自动宽度应用于MVC网格中的外键下拉菜单

@(Html.Kendo().Grid<Model>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.Name);
        columns.ForeignKey(p => p.CategoryId, (System.Collections.IEnumerable)ViewBag.Categories, "Id", "Name")
               .Title("Category")
               .Width(200)
               .AutoWidth(true);
        columns.Command(command => command.Destroy()).Width(110);
    })
    .ToolBar(toolbar => toolbar.Create())
    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .Pageable()
    .Sortable()
    .Scrollable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .Model(model =>
        {
            model.Id(p => p.Id);
            model.Field(p => p.CategoryId).DefaultValue(1);
        })
        .Create(create => create.Action("Create", "Home"))
        .Read(read => read.Action("Read", "Home"))
        .Update(update => update.Action("Update", "Home"))
        .Destroy(destroy => destroy.Action("Destroy", "Home"))
    )
)
