This is my solution to filter rows using a text that user inputs using textfield: 

textField.addTextChangeListener(new TextChangeListener() {

            @Override
            public void textChange(TextChangeEvent event) {
                Filterable filter= (Filterable) (table.getContainerDataSource());
                filter.removeAllContainerFilters();

                String filterString = event.getText();
                if (filterString.length() > 0) {
                    filter.addContainerFilter(new Like("columnName", "%"+filterString +"%"));
                }

            }
        });

I hope code is selfexplanatory.

filterString = checkBox.getValue().toString();
Filterable f = (Filterable)(table.getContainerDataSource());
        if(filters==null)
            filters=new TreeMap<Object, SimpleStringFilter>();
        SimpleStringFilter filter=filters.remove(propertyId);
            if (filter != null){
                f.removeContainerFilter(filter);
            }
            filter = new SimpleStringFilter(propertyId, filterString, ignoreCase, onlyMatchPrefix);
        filters.put(propertyId, filter);
        f.addContainerFilter(filter);

Just update your BeanContainer with new data. Here is an example of my code

public void refreshTableData() {
    getBeanContainer().removeAllItems();
    List<Customer> customers = customerDao.getByCustomerFilter(getCustomerFilterForm().getFilterItem().getBean());
    getBeanContainer().addAll(customers);
}

Where CustomerFilter is a bean that has all the search criteria data, that I fill it within a form earlier (e.g with comboboxes), and beanContainer is my table container data source.
