Format of my table

Dear communities:

Why did this happen?
My table is not balance in format


Can you explain what’s your exact issue ?

four columns are not the same
some are big some are small


open your child table doctype set column width for fields as per your requirement.

I can’t find this field in my doctype
could you please give me more detail ?

open any field row of your child table Doctype and check columns field under Display section.

thanks for your reply first
but all columns of them are be set the same
