Keyboard Accessibility: while tabbing the first element in celltable gets focus

[nidhizener]

I am working on adding keyboard accessibility to my application. When tabbing from on e widget to another if there is a celltable, it is included in the tabbing sequence. The cell table in not editable, still it gets into tabbing sequence. How do I remove the cell table from tabbing sequence? Is this known issue? Wondering if there are any work arounds? Any help will be appreciated.

What kind of Cell is this? Can you show part of the code that sets up the table?
Did you set KeyboardSelectionPolicy to DISABLED?
