Problem with Grid-Align inside TabBar

Hello

I have to grids together (like in the pictue). The first is without tabbar and the second with.
How can i delete the free space which you can see at the marked position and the second grid? I want to have the first column as close to the beginning as possible. I always get this space when i add an object to tabbar.

Thank you
