uint8: 1 | bIsLoading | True if this asset is currently being loaded; false otherwise |
 |
uint8: 1 | bShouldNotClearParentTablesOnEmpty | If this is true then the parent table array will not be cleared when EmptyTable is called |
 |
uint8: 1 | bUpdatingParentTables | True if we're already in the middle of updating parent tables for this asset |
   |
TArray< TObjectPtr< UDataTable > > | OldParentTables | Temporary copy used to detect changes so we can update delegates correctly on removal |
    |
TArray< TObjectPtr< UDataTable > > | ParentTables | Parent tables Tables with higher indices override data in tables with lower indices |
 |
TMap< FName, ERowState > | RowSourceMap |
