Question

我正在使用controlfx TableFilter属性来实现javafx tableview的过滤器可用性。它工作正常。但是，一旦将过滤器应用于特定列，并且在动态添加新行时，该行不会被过滤。或者换句话说，列值会自动添加到该列的过滤器中。预期的行为是，添加的行也应按照定义的过滤器进行过滤。 PFA解决问题的示例代码

I had the same problem. Perhaps there is some kind of bug in TableFilter by controlsfx. I got the solution by creating my tableview programmatically. Filter should applied after adding all TableColumns in the TableView.If you create table view programmatically then you are free to add columns dynamically.

Do not apply filters on TableColumns. instead of this, apply filter on TableView.

TableFilter.forTableView(my_table_view).apply();

controlfx TableFilter-动态添加行不会被过滤
