表不过滤

Question

我希望过滤器保留所有值，而不是重叠。我究竟做错了什么？我希望过滤器保留所有exp.substring(11,19)而不重叠

ArrayList<RowFilter<Object,Object>> arrLstColorFilters = new ArrayList<RowFilter<Object,Object>>();

if (time3[i].after(time1) && time3[i].before(time2)) {
    String exp = time3[i].getTime().toString();
    please.add(exp.substring(11, 19));
    RowFilter<Object,Object> blueFilter = RowFilter.regexFilter(exp.substring(11, 19),3);
    arrLstColorFilters.add(blueFilter);
}
sorter.setRowFilter(RowFilter.andFilter(arrLstColorFilters));

exp包含时间格式：“09:19:19”arrLstColorFilters中的每个值都没有显示
