Java 隐藏/显示jtable中的行

我用defaulttablemodel创建了一个表，上面有一个组合框。我需要根据组合框值（10,20,30,40）隐藏/显示已经创建和填充的行

private void newFilter（int numberOfRows）{
RowFilter筛选器=新的RowFilter（）{

公共布尔包含（RowFilter.Entry
当行被过滤后，上面的语句返回-1。因此，一旦一行被过滤，它将保持过滤状态

然后我尝试使用：

((TableRowSorter) table.getRowSorter()).setRowFilter(null);
((TableRowSorter) table.getRowSorter()).setRowFilter(filter);

试图重置筛选器，但这似乎不起作用，因为现在为“i”的值返回了0

所以最后我试着：

private void newFilter(int numberOfRows)
{
    final RowFilter<TableModel, Integer> filter = new RowFilter<TableModel, Integer>()
    {
        @Override
        public boolean include(RowFilter.Entry<? extends TableModel, ? extends Integer> entry)
        {
            int i = table.convertRowIndexToView(entry.getIdentifier());

            //System.out.println(i + " : " + numberOfRows + " : " + entry.getIdentifier());

            return i < numberOfRows;
        }

    };

    ((TableRowSorter) table.getRowSorter()).setRowFilter(null);

    SwingUtilities.invokeLater(new Runnable()
    {
        public void run()
        {
            ((TableRowSorter) table.getRowSorter()).setRowFilter(filter);
        }
    });

}

private void newFilter（int numberOfRows）
{
最终行筛选器=新行筛选器（）
{

public boolean include（RowFilter.entry）将来，发布一个适当的例子来说明问题。请参阅我的答案，以了解SSCCE.plus 1的示例，但使用and/or filter似乎更好
((TableRowSorter) table.getRowSorter()).setRowFilter(null);
((TableRowSorter) table.getRowSorter()).setRowFilter(filter);

private void newFilter(int numberOfRows)
{
    final RowFilter<TableModel, Integer> filter = new RowFilter<TableModel, Integer>()
    {
        @Override
        public boolean include(RowFilter.Entry<? extends TableModel, ? extends Integer> entry)
        {
            int i = table.convertRowIndexToView(entry.getIdentifier());

            //System.out.println(i + " : " + numberOfRows + " : " + entry.getIdentifier());

            return i < numberOfRows;
        }

    };

    ((TableRowSorter) table.getRowSorter()).setRowFilter(null);

    SwingUtilities.invokeLater(new Runnable()
    {
        public void run()
        {
            ((TableRowSorter) table.getRowSorter()).setRowFilter(filter);
        }
    });
