Add custom type

Problem/Motivation

current after lock table we have 2 options textfield and textarea and we have no other way to change to select or add something to attributes

Proposed resolution

this patch opens an easy way to customize the field by column or row with yml format
example you want change column 2 to select

col:
    2:
      type: select
      options:
        foo: foo
        foo2: foo2

example change row 2 to select

row:
    2:
      type: select
      options:
        foo: foo
        foo2: foo2

change row 2 column 3 to select

row_2_col_3:
   type: select
   options:
      foo: foo
      foo2: foo2
