Examples of javax.swing.table.DefaultTableModel.addColumn()

javax.swing.table.DefaultTableModel.addColumn()
Adds a column to the model. The new column will have the identifier columnName, which may be null. This method will send a tableChanged notification message to all the listeners. This method is a cover for addColumn(Object, Vector) which uses null as the data vector. @param columnName the identifier of the column being added
