Hi all,
hmmm...
To remove a Column you only have to save the removed column into a list. When you want to see the column again, only add it to the TableColumnModel.
For example:
public YourTable extends JTable{
  private Hashmap deletedColumns;
  public void removeColumn(Object columnIdentifier){
    TableColumnModel columnModel = getColumnModel();
    int index = columnModel.getColumnIndex(columnIdentifier);
    TableColumn column = columnModel.getColumn(index);
    if(deletedColumns == null)
      deletedColumns = new Hashtable();
    deletedColumns.put(columnIdentifier, column );
    columnModel.removeColumn(column);
  public void addColumn(Object columnIdentifier){
    TableColumnModel columnModel = getColumnModel();
    TableColumn column = (TableColumn )deletedColumns.remove(columnIdentifier);
    if(column != null)
      columnModel.addColumn(column);
}NOTE: I didnt compile the code, but this is the way to do it.
Take care, because the default models takes String as identifiers for the headers. That isnt right, because all Objects wich have a implemetation of the "toString" will be returned as a String...
