所以我在数据表中有一个日期列，其中有一个使用日期范围而不是日期选择器构建的自定义过滤器。
$('#idOfTheDateRangePicker').on('apply.daterangepicker',
function(ev, picker) {
var start_date = picker.startDate.format('DD.MM.YYYY');
var end_date = picker.endDate.format('DD.MM.YYYY');
var position = $(this).attr('position');
var min_date = createDate(start_date);
var max_date = createDate(end_date);
var filter = function(settings, data, index) {
var data_date = createDate(data[position]);
if(data_date >= min_date && data_date <= max_date) {
return true;
} else {
return false;
}
};
$.fn.dataTable.ext.search.push(filter);
var table = $('#thisTableId').DataTable();
table.draw();
$.fn.dataTable.ext.search.splice($.fn.dataTable.ext.search.indexOf(filter, 1));
});
对于返回日期在给定日期范围内的行，此过滤器效果很好。
问题是，当我单击列标题上的排序功能时，它将重置日期范围过滤器并显示所有行。但是，排序不会破坏我的所有非范围自定义过滤器，例如使用select或datepicker的过滤器，这些过滤器会将单个值传递给表列搜索。
我如何才能使上面的日期范围过滤器即使在单击排序按钮时仍适用于表格？
