How to add new line in label programatically?

Question

I have 5-10 labels in table cell,I want to start each label with new line.

 

In that cell some labels are hide according to condition, so labels which are not hide that will be started with new line.

 

If I'm using '</br>' in design mode then their will be empty space in that table cell.
