You have created custom EC in solution and would like to change column / row span for this EC.
Reproducing the Issue
From SDK, launch custom embedded component.
Select Embedded component.
You want to change column span from UI designer but this is not editable.
This is expected behaviour. Change of column span is not supported for EC's (embedded components) which are added using extensibility explorer.
Note: Additionaly, column span cannot be changed for custome EC's by KUT.
