IsHidden Attribute

In the OutputField element, you can set the IsHidden attribute to "true" to hide a column within a query view or list builder. By default, any column defined within the query by the ViewImplementation or TVFImplementation elements is visible as a field in a query view or as an available column in a list builder. To hide a column, you just add the IsHidden attribute to its OutputField element and set it to "true."
