TableElementHandler and ColumnElementHandler don't handle translate, this ticket to add that feature
it also resolve bellow issue
1. define pack-out for MTable with type use "Data Single"
so it export translate also
2. do packin then get issue because parent element.recordId = null
There is a long conversation in pull request 168
Bringing my last comment:
After re-reviewing this I think the table AD_Column_Trl can be simply replaced by a view, as explained by Heng Sin above it's always getting the value from AD_Element_Trl.
