Java JTable 更新行

我正在创建一个像这样的 JTable：

           String[] colName = new String[] {
               "ID#", "Country", "Name", "Page titel", "Page URL", "Time"
           };
           Object[][] products = new Object[][] {
               {
                   "123", "USA", "Bill", "Start", "http://www.url.com", "00:04:23"
               },

               {
                   "55", "USA", "Bill", "Start", "http://www.url.com", "00:04:23"
               }

           };

           dtm = new DefaultTableModel(products, colName);
           table = new JTable(dtm);

我怎样才能通过ID更新行？我想更新 ID 等于 55 的整行。

编辑：我知道如何按 rowID 删除，但如何实际更新单元格？

  public void removeVisitorFromTable(String visitorID) {
    int row = -1; //index of row or -1 if not found

    //search for the row based on the ID in the first column
    for(int i=0;i<dtm.getRowCount();++i)
        if(dtm.getValueAt(i, 0).equals(visitorID)) {
            row = i;
            break;
        }

    if(row != -1) {
        dtm.removeRow(row);//remove row
    } else {

    }
}

您可以使用DefaultTableModel#setValueAt(java.lang.Object, int, int) http://docs.oracle.com/javase/7/docs/api/javax/swing/table/DefaultTableModel.html#setValueAt%28java.lang.Object,%20int,%20int%29

or

DefaultTableModel#setDataVector(java.util.Vector, java.util.Vector) http://docs.oracle.com/javase/7/docs/api/javax/swing/table/DefaultTableModel.html#setDataVector%28java.util.Vector,%20java.util.Vector%29

Edit:

Example:

private void updateRow(String visitorID, String[] data) {
    if (data.length > 5)
        throw new IllegalArgumentException("data[] is to long");
    for (int i = 0; i < dtm.getRowCount(); i++)
        if (dtm.getValueAt(i, 0).equals(visitorID))
            for (int j = 1; j < data.length+1; j++)
                dtm.setValueAt(data[j-1], i, j);
}
