Printing QTableWidget to an DIN A4 page

[Mady]

How can I layout the printout to an pdf/page of a QTableWidget ?
This is what i want to do (even for just a single tip for one of them i am a million times thankfull):
- set the width of the Table
- set the color of the headers of the Table
- set the startingpoint of the Table printout to the middle of the page ?
- set an picture on the lopright of the page
- inserted an horizontal line somewhere in the page

I created a destopapp with and QTableWidget in it. I am using QtPrintSupport to print it/make an pdf of it.
Right now i am only able to inseart the table and a picture but i am not able to set the size of them and the location. Help will be much appreciated.
I am using python 3.6 and pyqt5.

Here is my code so far (in shorted to only show relevent stuff)

for the color of the header your code is correct.
I only change this line

stylesheet = "::section{Background-color:rgb(190,1,1);border-radius:14px}"

to

stylesheet = "::section{Background-color:rgb(0, 0, 255);border-radius:14px;font: bold}"

.I will check later

The Layout is not good, resizing the window should resize the Table too.
The PushButton is no longer visible when you zoom out of the window.

border-radius:14px does nothing here, value is too big

using this gives me rounded corners

stylesheet = "::section{background-color:blue;color: lightgray; border: 1px solid black; border-radius:10px;font: bold}"
