Adjust Size of List Items in Columns

We have an option of adjusting our Row Size, this is useful when we don't want to show the dimension of the module. There are cases when we don't want to show Rows as well as Columns of the module like the typical 2-D/excel way of displaying things. 

Hence Proposing an idea of Having an ability to adjust the Size of the List items when the list is in columns. Basically the idea is to hide not just first column but the first row of the 2-D module where the First/Header Row represents the List items
