How to add ITable to ArcMap TOC

Is there anyway to add ITable to ArcMap TOC? I'm trying to edit a table which is added through WorkspaceFactory.OpenFromFile. But I get the error "Error HRESULT E_FAIL has been returned from a call to a COM component", see the code below. I found out that if I add a featurelayer along with the table and add the featurelayer to TOC, I don't get the error. Any suggestions?

            IWorkspaceFactory pWorkspaceFactory = new SdeWorkspaceFactory();             IWorkspace workspace = pWorkspaceFactory.OpenFromFile(path, 0);             IPropertySet propSet = workspace.ConnectionProperties;              IFeatureWorkspace pWorkspace = pWorkspaceFactory.Open(propSet, 0) as IFeatureWorkspace;             ITable table = pWorkspace.OpenTable("GISLCSA.GISEDITOR.MetaID");             ILayer tableLayer = table as ILayer;             pMetaIDTable = table as ITable;              UID uid = new UIDClass();             uid.Value = "esriEditor.Editor";             IEditor editor = m_application.FindExtensionByCLSID(uid) as IEditor;              if (editor.EditState == esriEditState.esriStateNotEditing)             {                 try                 {                     editor.StartEditing(workspace );                 }                 catch (Exception e)                 {                     MessageBox.Show(e.Message);                 }             }

You can create a new IStandaloneTable, set it's Table and Name properties and add it to the map via IStandaloneTableCollection. You could also just start your edit session using IWorkspaceEdit instead of using the Editor extension.

Perfect! Thank you Neil!
