how to divide QGridLayout into rows and columns at Design Time in QT ?

I want to design one form where i want to have 2 columns and 7 rows . I am designing using QTCreator but i am not getting any option of giving rows/columns.

It shows only these properties

See Using Layouts in Qt Designer. For you the most important paragraph is this:

The simplest way to manage objects is to apply a layout to a group of existing objects. This is achieved by selecting the objects that you need to manage and applying one of the standard layouts using the main toolbar, the Form menu, or the form's context menu.

1. place your widgets on the form
2. arrange them into 2 columns and 7 rows
3. select all of them
4. right click on the selected widgets
5. select Lay Out in a Grid on the context menu.

QLayout structure is created dynamically as you add widgets to it, there's no way to predefine how many rows/cols a layout have. Maybe you are using the wrong approach to achieve your goal.
