public void showTotalSummary()
{
JFrame totalSummary = new JFrame("Total Leave Credit Summary");
totalSummary.setSize(970, 523);
totalSummary.setResizable(false);
totalSummary.setLocationRelativeTo(null);
totalSummary.setVisible(true);
panelTotalSummary = new JPanel();
panelTotalSummary.setBorder ( (Border) new TitledBorder ( new EtchedBorder (), "Display Area" ) );
totalSummary.add(panelTotalSummary);
String[] headings = {"Employee No.", "Employee Names", "Vacation Leave", "Tardiness", "Sick Leave", "Nonattendances", "Total Leave Earned "};
String [][] data = {{"01", "Adlawan","10.50","2.50","20", "4", "30.50"},
{"02","Angeles","20.10","5.90","25","6","45.10"},
{"03","Benenoso","30.70","7.60","34","8","64.70"},
{"04","Bermas","20","4.10","25","3","45"}};
JTable totalSummaryTable = new JTable(data, headings);
totalSummaryTable.getTableHeader().setFont( new Font( "Tahoma" , Font.BOLD, 12 ));
Font f = new Font("Arial", Font.ITALIC, 13);
totalSummaryTable.setFont(f);
totalSummaryTable.setGridColor(Color.BLUE);
totalSummaryTable.setPreferredScrollableViewportSize(new Dimension(900, 400));
totalSummaryTable.setFillsViewportHeight(true);
JScrollPane jcp = new JScrollPane(totalSummaryTable);
jcp.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );
panelTotalSummary.add(jcp);
}
使用这些代码我能够将数据发布到我的JTable。我的问题是我如何从文件中读取从该文件获取数据并将数据发送到JTable的一行?我知道如何从文件中读取并将这些数据发送到JTextField。我将如何执行相同的过程,但不是将数据发送到JTextField,我希望将文件中的数据从JTabel发送到一行。任何人持有的任何人都将非常感激。

您需要做的是实现自己的 TableModel 。有关"How to Use Tables"的本教程将有助于理解表在Swing中的工作方式。
基本上,您需要做的是创建一个扩展AbstractTableModel的类,并至少为以下三种方法提供实现:
public int getRowCount();
public int getColumnCount();
public Object getValueAt(int row, int column);
您可以使用模型使其可以将数据保存在数组,矢量或哈希映射中,也可以从外部源获取数据,例如读取文件并从中获取数据。
