问如何打印出JTable的特定行/列？

EN

// get column num from settings
int num = gridSettings.getColumnsOnPage();// first <num> columns of the table will be printed   

final TableColumnModel model = table.getColumnModel();

// list of removed columns. After printing we add them back
final List<TableColumn> removed = new ArrayList<TableColumn>();

int columnCount = model.getColumnCount();

// hiding columns which are not used for printing
for(int i = num; i < columnCount; ++i){
    TableColumn col = model.getColumn(num);
    removed.add(col);
    model.removeColumn(col);
}                                                   

// printing after GUI will be updated
SwingUtilities.invokeLater(new Runnable() {
    public void run() {
        // table printing
        try {
            table.print(PrintMode.FIT_WIDTH, null, null, true, hpset, true); // here can be your printing
        } catch (PrinterException e) {
            e.printStackTrace();
        }

        // columns restoring
        for(TableColumn col : removed){
            model.addColumn(col);
        }
    }
});
