多列上的Java RowFilter

Question

我想在多列上对JTable进行排序/过滤，f .E。

Column1  Column2
   a        1
   b        2
   c        2

我想通过 Column1 = b 和 Column2 = 2 对此表进行排序。

MyTableModel model = new MyTableModel();
sorter = new TableRowSorter<MyTableModel>(model);
table = new JTable(model);
table.setRowSorter(sorter);

...

private void newFilter() {
    RowFilter<MyTableModel, Object> rf = null;
    //If current expression doesn't parse, don't update.
    try {
        rf = RowFilter.regexFilter(filterText.getText(), 0);
    } catch (java.util.regex.PatternSyntaxException e) {
        return;
    }
    sorter.setRowFilter(rf);
}

但是如何对多个列进行排序？

Answer 1

您可以创建RowFilter.AndFilter并传递所需的所有过滤器：

List<RowFilter<M, O>> listOfFilters = new ArrayList<>();
... add filters into list
RowFilter.andFilter(listOfFilters);

Answer 2

只需删除参数＆＃34; 0＆＃34;从RowFilter对所有列进行排序：

rf = RowFilter.regexFilter(filterText.getText());
