Auto expand other column to rest of the space while one column height is hardcoded

[anisursamsung]

Lets say I have a column layout of two components vertically.
Let's say first column takes 30 height. The second column if set height Auto takes full height of the parent. If we could pass Weight=1, it could take rest of the height (i.e. parent height -30) instead of full height.
Right now, our best shot is put the height manually by math of parent height - 30 or percent base. Thanks.
