[Juergen Spitzmueller]

commit 8a17cc01e0fa81e2730ef96887d4bffbb641cfd0

    Implement (basic) ct for tabular-feature delete-row and delete-column
    
    Fixes part of #8469
    
    For a proper fix that works with change-reject as well as with hide
    changes in output, we need to implement
    ct information in tabular's row and column.
