HtmlHelper in ASP.NET MVC3 that uses Action <T> as a template: Razor syntax?

Question

Let me preface this by saying that there may be a better way to do this, and Razor highlights the way. In any case, I have an HTML helper that acts like a sort repeater, but after an arbitrary number of repetitions, it inserts an alternative pattern. The most obvious use? Tables that start a new row after x-cells. The helper is as follows:

public static void SeriesSplitter<T>(this System.Web.Mvc.HtmlHelper htmlHelper, IEnumerable<T> items, int itemsBeforeSplit, Action<T> template, Action seriesSplitter)
{
    if (items == null)
        return;
    var i = 0;
    foreach (var item in items)
    {
        if (i != 0 && i % itemsBeforeSplit == 0)
            seriesSplitter();
        template(item);
        i++;
    }
}

And in the Webforms view, the usage is as follows:

<table>
    <tr>
    <% Html.SeriesSplitter(Model.Photos, 4, photo => { %>
            <td><img src="<%=ResolveUrl("~/Thumbnail.ashx?id=" + photo.ID)%>" alt="<%=Html.Encode(photo.Title)%>" /></td>
    <% }, () => { %></tr><tr><% }); %>
    </tr>
</table>

Func<object, HelperResult> ( , ):

public static void SeriesSplitter<T>(this System.Web.Mvc.HtmlHelper htmlHelper,
                                     IEnumerable<T> items,
                                     int itemsBeforeSplit,
                                     Func<object, HelperResult> template,
                                     Func<object, HelperResult> seriesSplitter) {
    //pretty  much same code here as before
}

@Html.SeriesSplitter(Model.Items, 3, @<td>item.Id</td>, @:</td><td>
)
