QtDesigner reset some attributes of QTableWidget despite saving

[never_ever]

Hi,
I make some gui using QtDesigner, and lately I have problem with QTableWidget. I have 4 tables -> each two tables are in QTabWidget tab, because they show the same kind of data according to selecting object.
So it looks like this, I have:

QTabWidget tabWid

• tab1:
  • QTableWidget tableData1;
  • QTabelWidget tableResults1;
• tab2:
  • QTableWidget tableData2;
  • QTabelWidget tableResults2;

I setted that in all tables horizontal headers are visible;
Problem is that when I open again .ui file in QtDesigner (from Visual Studio 2010) - in two tables (tableResult1 and tableResult2) that headers are invisible and setHorizontalHeaderVisible is unchecked. It happens despite of saving .ui file

I have been using QtDesigner and Visual Studio for a long time and it happens me first time.

I also have QTableWidgets inside tabs of a QTabWidget and have had this problem for a long time. Every time the .ui file is saved in QtCreator it sets the horizontal headers of all my tables to invisible except for the first table.
