select a field value and make it a new field name

[#1]

Hello

I want to select a field value (text) and create a new field. The new field will contain the rest of the values as field values.

Eg. Letters: {A, B, C, D, E} Original field named Letters containing A B C D E

I want to make a new table with two fields

Letters: {A, B, C, D, E} Original field named Letters containing A B C D E

A: {B, C, D,E} New field named A contailing B C D E
