如何在一份工作中並排打印多張表格？

Question

如何並排打印三個不同的表格或將它們一起添加到一個打印中？因爲以下代碼單獨打印並在不同的頁面中打印。 我對JTable的打印方面知之甚少。

我正在使用NetBeans 8.0。

或者我可以將數據導入到excel文件並從那裏打印？這是否合理？ 編輯：所有三張桌子在打印時必須並排在一起，無論其縱向或橫向如何。甚至更好，如果所有的表或連接，並由多列代替三個獨立的表。

PrinterJob job = PrinterJob.getPrinterJob(); 
PrintRequestAttributeSet asset = new HashPrintRequestAttributeSet(); 
PageFormat pf = job.pageDialog(asset); 
job.setPrintable(new recording_system(), pf); 
boolean ok = job.printDialog(asset); 
if (ok) { 
    try { 
     jTstudents.print(JTable.PrintMode.NORMAL); 
     jTscores.print(JTable.PrintMode.NORMAL); 
     jTresults.print(JTable.PrintMode.NORMAL); 
    } catch (PrinterException ex) { 
     /* The job did not successfully complete */ 
    } 
} 

的表格看起來像這樣

實施組合所有車型的TableModel類。

TableModel model = new ParallelTableModel(jTStudents.getModel(), 
              jTScores.getModel(), 
              TResults.getModel()); 
JTable totalTable = new JTable(model); 

複製表頭。 然後totalTable.getPrintable用於打印。

/** 
* Table Model composed from side-by-side table models. 
*/ 
public class ParalleTableModel extends AbstractTableModel { 

    private final TableModel[] models; 

    public ParalleTableModel(TableModel... models) { 
     this.models = models; 
    } 

    @Override 
    public int getRowCount() { 
     return models[0].getRowCount(); 
    } 

    @Override 
    public int getColumnCount() { 
     int count = 0; 
     for (TableModel model : models) { 
      count += model.getColumnCount(); 
     } 
     return count; 
    } 

    @Override 
    public String getColumnName(int columnIndex) { 
     int count = 0; 
     for (TableModel model : models) { 
      int n = model.getColumnCount(); 
      if (columnIndex < count) { 
       return model.getColumnName(columnIndex - count); 
      } 
      count += n; 
     } 
     throw new IndexOutOfBoundsException(); 
    } 

    @Override 
    public Class<?> getColumnClass(int columnIndex) { 
     int count = 0; 
     for (TableModel model : models) { 
      int n = model.getColumnCount(); 
      if (columnIndex < count) { 
       return model.getColumnClass(columnIndex - count); 
      } 
      count += n; 
     } 
     throw new IndexOutOfBoundsException(); 
    } 

    @Override 
    public boolean isCellEditable(int rowIndex, int columnIndex) { 
     int count = 0; 
     for (TableModel model : models) { 
      int n = model.getColumnCount(); 
      if (columnIndex < count) { 
       return model.isCellEditable(rowIndex, columnIndex - count); 
      } 
      count += n; 
     } 
     throw new IndexOutOfBoundsException(); 
    } 

    @Override 
    public Object getValueAt(int rowIndex, int columnIndex) { 
     int count = 0; 
     for (TableModel model : models) { 
      int n = model.getColumnCount(); 
      if (columnIndex < count) { 
       return model.getValueAt(rowIndex, columnIndex - count); 
      } 
      count += n; 
     } 
     throw new IndexOutOfBoundsException(); 
    } 

    @Override 
    public void setValueAt(Object aValue, int rowIndex, int columnIndex) { 
     int count = 0; 
     for (TableModel model : models) { 
      int n = model.getColumnCount(); 
      if (columnIndex < count) { 
       model.setValueAt(aValue, rowIndex, columnIndex - count); 
      } 
      count += n; 
     } 
     throw new IndexOutOfBoundsException(); 
    } 
}
