For example, you can widen the datatype column if it contains user-defineddatatype names that are too long to see in their entirety.
例如，如果“数据类型”列中包含用户定义的数据类型名称，该名称太长而无法看到其全部，则可加宽该列。

To model more complex designs, you can type tags by stereotypes and meta-classes, in addition to Boolean, string, integer, user-defineddatatype, and terms.
