如何在Vaadin Grid中实现多个过滤条件？

在Vaadin Grid中实现多个过滤条件可以通过以下步骤实现：

创建一个Grid对象，并设置数据源。

Grid<Person> grid = new Grid<>();
grid.setItems(personList);

创建一个Grid的过滤器组件，用于设置多个过滤条件。

GridMultiFilter<Person> filter = new GridMultiFilter<>(grid);

为Grid的每个列添加过滤条件。

filter.setFilter(firstNameColumn, new TextField(), String::startsWithIgnoreCase);
filter.setFilter(lastNameColumn, new TextField(), String::startsWithIgnoreCase);
filter.setFilter(ageColumn, new NumberField(), (person, value) -> person.getAge() == value.intValue());

将过滤器组件添加到Grid的顶部工具栏。
