[QML] The TabOrder problem of TableView

About the TabOrder of TableView in Qt 5.3.1, the action is different from Qt 5.2.1.
sample:
There is a tableView that has 3 Columns and 2 Rows, the title of Column are [Column1..3],
and the control of Row is TextField(user can input something), the ids of these control are [TextField1..6].
-----------------------------------------
Column1 Column2 Column3
TextField1 TextField2 TextField3
TextField4 TextField5 TextField6
-----------------------------------------
In Qt5.2.1 the TabOrder is TextField1->TextField2...>TextField4>...->TextField6
But in Qt5.3.1 the TabOrder is TextField1->TextField2->TextField3, another row can not gets the foucs by pushing Tab key.

The sourcecode is also attached.(TableViewReport.qml)

Maybe it is not a bug, I just want to know the solution of this problem.
Thanks for you help!
