Razor-based htmlhelper MVC3 with model-based lambda expressions

I am creating a free HtmlHelper in MVC - for creating an HTML-based grid. I know about mvc contrib and WebGrid, but I make my own and have a specific problem:

I need to enter this:

@Html.DSGridFor().AddColumn(x=>x.FirstOrDefault().Message)

but I want to type this:

@Html.DSGridFor().AddColumn(x=>x.Message)

The code that gets called when I start with @ Html.DSGridFor () is taking in a page-based model.

public static DSGridHelper<TModel> DSGridFor<TModel>(this HtmlHelper<TModel> html)
{
   return new DSGridHelper<TModel>(html);
}

and then in the DSGridHelper class I have the following:

public DSGridHelper<TModel> AddColumn(Expression<Func<TModel, dynamic>> property, string HeaderText = null)
        {
            string ColumnName = (property.Body as MemberExpression).Member.Name;

            DSGridColumn DSGC = new DSGridColumn();
            DSGC.ColumnName = ColumnName;
            DSGC.HeaderText = HeaderText ?? ColumnName;
            DSColumnList.Add(DSGC);

            return this;
        }

public List<DSGridColumn> DSColumnList { get; set; }

and the column class is currently really basic:

  public class DSGridColumn
    {
        public DSGridColumn()
        {

        }

        public string ColumnName { get; set; }
        public string HeaderText { get; set; }

    }

I can get this code to work with row-based column names, but I want the ad code on the razor page to be simple in format and strongly typed. At the moment, I need to enter x => x.First (). Message, but I really only need x => x.Message to identify the column.

@(Html.DSGridFor3().AddColumn(x => x.Message)
                   .AddColumn(x => x.Host)
                   .ToMvcString())

public static DSGridHelper3<T> DSGridFor3<T>(this HtmlHelper<IEnumerable<T>> htmlHelper)
{
         return new DSGridHelper3<T>(htmlHelper);

        }

        public DSGridHelper3<T> AddColumn(Expression<Func<T, object>> property)
        {
            string columnName = (property.Body as MemberExpression).Member.Name;
            DSGridColumn DSGC = new DSGridColumn();
            DSGC.ColumnName = columnName;
            DSGC.HeaderText = columnName;
            DSColumnList.Add(DSGC);

            return this;
        }

        public MvcHtmlString ToMvcString()
        {
            sb.Append("<table>");
            sb.Append("<tr>");
            sb.Append("<td>");
            sb.Append("hello world within a table");
            sb.Append(@"</td>");
            sb.Append("<td>");
            sb.Append("hello world within a table");
            sb.Append(@"</td>");
            sb.Append(@"</tr>");
            sb.Append(@"</table>");


            return new MvcHtmlString(sb.ToString());

        }
