I can programmatically create the view.  I am not sure how to get it into 2 columns.  here is my code.
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using System.Collections.Specialized;
namespace SharePointProject3.WebPart1
    [ToolboxItemAttribute(false)]
    public class WebPart1 : WebPart
        protected override void CreateChildControls()
            using (SPSite site = new SPSite("http://site"))
                using (SPWeb web = site.OpenWeb())
                    web.AllowUnsafeUpdates = true;
                    //Get the List
                    SPList ProjectDocuments = web.Lists["Vendor"];
                    //Set the View fields
                    StringCollection ViewFields = new StringCollection();
                    ViewFields.Add("Type");
                    //Set the View Filter and Sort order
                    string viewQuery = @" <GroupBy Collapse=""TRUE"" GroupLimit=""100""> <FieldRef Name=""SubCategory""/>
</GroupBy><Where><And><Eq><FieldRef Name=""VendCat""/><Value Type=""Text"">eCommerce and Marketing</Value></Eq><Eq><FieldRef Name=""Active""
/><Value Type=""Boolean"">1</Value></Eq></And></Where>";
                    //Create the view
                    ProjectDocuments.Views.Add("Proposal Documents", ViewFields, viewQuery, 100, true, false);
                    //Update the List
                    ProjectDocuments.Update();
                    web.AllowUnsafeUpdates = false;
                    web.Dispose();
                site.Dispose();
