在按钮单击时从jtable中删除选定的行

Question

我想从java中的表中删除Selected行.应该在按钮点击时执行该事件.如果有人帮忙,我会感激不尽的...

例如,有一个名为sub_table的表,其中包含3列,即sub_id,sub_name,class.当我从该表中选择其中一行并单击删除按钮时,应删除该特定行.

Answer 1

这很简单.

• 添加 ActionListener按钮.
• 从附加到表的模型中删除选定的行.

示例代码:(有2列的表)

Object[][] data = { { "1", "Book1" }, { "2", "Book2" }, { "3", "Book3" }, 
                    { "4", "Book4" } };

String[] columnNames = { "ID", "Name" };
final DefaultTableModel model = new DefaultTableModel(data, columnNames);

final JTable table = new JTable(model);
table.setSelectionMode(javax.swing.ListSelectionModel.SINGLE_SELECTION);


JButton button = new JButton("delete");
button.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent arg0) {
        // check for selected row first
        if (table.getSelectedRow() != -1) {
            // remove selected row from the model
            model.removeRow(table.getSelectedRow());
        }
    }
});
