SOLVED - How to have category row in the same vertical position as data row?

I am using tableview. When you use the category rows, they appear above the other data rows. 

I am looking a way to have the category row to be in the same vertical position (y) as the data row. 

I cannot simply insert the category row content inside my first data row because I would lose the category row effect of being always shown on screen.

For example:

Normal behavior:

Category A Data row 1 Data row 2 Data row 3 Category B Data row 4 Data row 5

What I want:

Category A   Data row 1 Data row 2 Data row 3 Category B   Data row 4 Data row 5

Any ideas?

I tried using category row with height = 0 but didn’t work pretty well…

UPDATE: I was able to get that behavior by modifying the tableview source code.
