How Designer Supports Tables
With the exception of String table, Designer does not provide a separate data type for tables. However, tables can appear as document lists or Objects. Tables that are instances of com.wm.util.Table appear as document lists in Designer. These tables can be used as document lists in flow services. Services in the WmDB package use tables that are instances of wm.com.util.Table.
Tables can also be declared as Objects. Objects or user-defined table-like objects that do not implement the com.wm.util.pluggable.WMIDataList interface appear as Objects of unknown type in Designer.
