TableField behaves in the same manner as TableListField, however allows the addition of fields and editing of attributes specified, and filtering results.

Caution: If you insert DropdownFields in the fieldTypes-array, make sure they have an empty first option. Otherwise the saving can't determine if a new row should really be saved.

Caution: TableField relies on {@FormResponse} to reload the field after it is saved. A TableField-instance should never be saved twice without reloading, because otherwise it can't determine if a field is new (=create) or existing (=update), and will produce duplicates.

• todo: We should refactor this to support a single FieldSet instead of evaluated Strings for building FormFields
