SCT / Qt5 Fixes: Column hiding, widths and reside mode problems [5877] [2]
Bug Number: 5877
Release notes (y/n): Yes
For Release Nums: 7.1 and, after testing, 7.0.2

Followup changes, after David's testing, to apply QHeaderView recreation 
also to the _vertical_ headers (for both QTableViews, the row header table 
and the data table).  The need for this was demonstrated by a new bug model 
and SCT having a horizontal timestep axis orientation (where slots are rows 
rather than columns).  See bug5877b.mdl.gz and bug5877b.sct.gz.

Note that neither of an SctView's two QTableViews' _vertical_ headers have 
any content.  SCT row header display content is shown in normal QTableView 
cells within the Row Header Table.  (The SCT series tab is implemented with 
two QTableViews, side-by-side).
