Examples of prefuse.data.Table.addColumn()

prefuse.data.Table.addColumn()
Add a column with the given name and data type to this table. @param name the data field name for the column @param type the data type, as a Java Class, for the column @see prefuse.data.tuple.TupleSet#addColumn(java.lang.String,java.lang.Class)
