UIViewController with two UITableView and Autolayout

Question

I have a UIViewController with two UITableView like this

when the interface rotate I would like this interface

but with Autolayout I can't be able to achieve this.

Here the constraints for table view A:

• Leading space
• Bottom space
• Top space
• Align center Y

and for table view B

• Trailing space
• Bottom space
• Top space
• Align center Y

and here the result:

If I add the constraint horizontal space between table view to 0 here is the result

How can I solve it without setting programmatically the frame? I wanna using Autolayout.

Solution based on @sha answer

Constraints for table view A:

• Leading space
• Bottom space
• Top space
• Width equals to B
• Horizontal space from B = 0

and for table view B

• Trailing space
• Bottom space
• Top space
• Width equals to A
• Horizontal space from A = 0

Answer 1

Remove align Y constraint (you don't need it if they take all available height) and add one to make width the same for A and B.
