It looks like most of your example fields would be strings. To add types you would add the type to the columnDefs. A list of acceptable types can be found here in the "types" section. ColumnDef Documentation

  columnDefs: 
  [
    { name:'firstName', field: 'first-name', type: 'string' },
    { name:'1stFriend', field: 'friends[0]', type: 'string' },
    { name:'city', field: 'address.city', type: 'string' },
    { name:'getZip', field: 'getZip()', enableCellEdit: false, type: 'string' }
  ]

EDIT: I see your questions ask specifically how to do this on a cell. I don't know why you would want to do this usually all cells of a column share a type.
