My Array doesnt follow my window

[aftalib]

Hello, i am currently working on an UI and im having a hard time with layouts (as you can see on the screen)

i want my array to follow the size of the window when i stretch it, so i dont get these blank spaces as you can see on the right of the arrays and a little on the bottom. I am already using layouts for this : my QTableView is resizing with the windows, but not my array in it.

How can i do this?

thanks in advance..

@aftalib Sorry, it is not clear what you mean. What array? Can you also draw what you want to get?

@jsulm i would like my columns with the numbers in it to follow my QTableView when i increase the size of my window, like this :

sorry english is not my native language, array might not be the right word.

@aftalib This is not related to layouts.
See
"By default, the cells in a table do not expand to fill the available space." in https://doc.qt.io/qt-5/qtableview.html

@jsulm Oh my god, thank you so much. i had no idea that was related to headers, i thought i was a layout displaying problem. thank you.
