For example, if I need to add something special in the doctype, like new table (not same current existed table in erpnext) with totally new code, colors and actions, something can not be done using the current allowed fields. How to do this?
No, I do not mean like this.
How I can create a table using html and javascript? I need to build the table with special features, shape and color … I do not need to have table like the table that are used in the doctype.
