Typically you would want to keep your views as clean as possible with little to no logic. I would suggest moving your role checking logic into a controller action and rendering a partial view based on the users role.

You can use ChildActions and the Html.Action extension method to get this wired up.

From MSDN:

A child action method renders inline HTML markup for part of a view instead of rendering a whole view. Any method that is marked with ChildActionOnlyAttribute can be called only with the Action or RenderAction HTML extension methods.

In your project, create a new Controller called Dashboard and added a single Action called BuildTable.

public class DashboardController : Controller
{
    [ChildActionOnly]
    public ActionResult BuildTable()
    {
        if (Roles.IsUserInRole("Administrator"))
        {
            return PartialView("_AdminTable");
        }

        return PartialView("_SupportTable");
    }
}

Include the following line in the view where you want the dashboard table to appear.

@Html.Action("BuildTable", "Dashboard")
