Constructor Detail

• MetaColumnModel

  public MetaColumnModel​(javax.swing.table.TableColumnModel baseColumnModel,
                         javax.swing.table.TableModel tableModel)

  Constructs a new MetaColumnModel from a base ColumnModel and a TableModel. The base ColumnModel is taken as the initial list of columns that can appear in this ColumnModel, but they can be deleted from and reinstated to this model without affecting the base. Subsequent changes to the base don't change this either.

  Parameters:

  baseColumnModel - the base ColumnModel

  tableModel - the TableModel which supplies the data for the columns this object describes; must refer to the same data as baseColumnModel
