JTable Double-Object in the clipboard

Question

Hello together,
this is my first posting here.
I've a JTable with Double-Objects. The Double-Objects in the JTable Cells are shown in the
Format *1.000,99*. I used a Renderer to Format the Value in the Cells.
If I use the STRG+C to Copy the Table Cells to Clipboard, the Values lose the format and the above Value is shown as follows:
*1000.99* in the Clipboard.
How can i tell Java that it use the rendered Format *1.000,99*
Greetings

In My TableModel the Value is in Double-Type. How can i manipulate the String Representation. Here is the The Model-Class
public class JDBCTableModel extends AbstractTableModel {
     Object[][] contents;
     String[] columnNames;
     Class[] columnClasses;
     String sql;
     Boolean[] editierbareSpalten;
     public JDBCTableModel(){
          super();
          contents = new Object[0][0];
     // AbstractTableModel methods
     public int getRowCount() {
          return contents.length;
     public int getColumnCount() {
          if (contents.length == 0)
               return 0;
          else
               return contents[0].length;
     public Object getValueAt(int row, int column) {
          return contents[row][column];
     public void setValueAt(Object o,int row, int column) {
          contents[row][column]=o;
     // overrides methods for which AbstractTableModel
     // has trivial implementations
     public Class getColumnClass(int col) {
          return columnClasses[col];
     public String getColumnName(int col) {
          return columnNames[col];
public boolean isCellEditable(int row, int col) {
//Note that the data/cell address is constant,
//no matter where the cell appears onscreen.
     try{
          return this.editierbareSpalten[col];
     }catch(Exception e){
          return false;
     public void setContent(Object[][] contents,String[] columnNames,Class[] columnClasses){
          setColumnClasses(columnClasses);
          setColumnNames(columnNames);
          setContent(contents);
          editierbareSpalten=new Boolean[columnNames.length];
          this.fireTableStructureChanged();
     public void setColumnClasses(Class[] columnClasses){
          this.columnClasses=columnClasses;
     public void setColumnNames(String[] columnNames){
          this.columnNames=columnNames;
     public void setContent(Object[][] contents){
          this.contents=contents;
}
