1. UI::TableValueTypeString
2. UI::TableValueType::String
3. UI::TableValueType[:string]
4. :table_value_type_string
5. :string

I think No.1 and No.5 are good.
The implementation of No.1 is very easy, just copy and paste the constants, and No.5 may be done in the future if necessary.

No.1 done! cf578f2
