正如我已經回答了here,我解決它通過在打印前中隱藏列,並打印後恢復列:
// 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);
}
}
});
用於打印JTable中的特定部分,只改變一點點這個代碼。
這樣做的好處是,用戶可以準確地看到要打印的內容,就像打印預覽一樣。 – 2010-04-24 18:08:00
