TableView.replaceDataSource(workspace_path, workspace_type, dataset_name, {validate})
The replaceDataSource method on the TableView object is similar to the findAndReplaceWorkspacePath method, but in addition to being able to change a workspace type, the dataset can also be changed. This is the only method that enables you to replace a table's dataset within a workspace. This is especially useful when the name of a dataset is different in the new workspace.
I have script that does everything I want, except that I create two pivot tables... I want these two dbf tables to automatically be added to ArcMap after the script runs. Is it arcpy.MakeTableView_management? For feature classes I used MakeFeatureLayer and the ApplySymbology... but can't seem to find anything for DBF tables
