fix [#7477]

Description

Fix column layout issue, the column flex is set error For px, we only need to set width and height For weight, we set flex For auto, we should set flex to 0, and not set size, it will calculate the size with children For stretch, we set flex to 1 And we should set the flexShrink to point up which element need to scale

Precedence order of displaying elements with the width attribute px > weight > auto > stretch
