No of columns more than 5 in child table view

I know the limit is 11 of fields in a table but there are only 5 fields being shown even if I added more in list view. How to show more fields in a child table more than 5?

11 columns not 11 fields

Some fileds can have two or more columns

You need to reduce the size of some fileds by reducing their columns to add more fields

Oh I thought its fields, thankyou for clarifying confusion.
