在这方面有两个悬而未决的问题： Applying multiple filters in ClosedXML (SetAutoFilter) 和 ClosedXML Excel filter rows by values in multiple columns 此代码将在最后一个范围内留下一个过滤器：

var wb = new XLWorkbook();
            var ws = wb.Worksheets.Add("AutoFilter");
            ws.Cell("A1").Value = "Names";
            ws.Cell("A2").Value = "John";
            ws.Cell("A3").Value = "Hank";
            ws.Cell("A4").Value = "Dagny";

            var r1 = ws.Range("A1", "A4");
            r1.SetAutoFilter();

            ws.Cell("B1").Value = "Names";
            ws.Cell("B2").Value = "John";
            ws.Cell("B3").Value = "Hank";
            ws.Cell("B4").Value = "Dagny";
            var r2 = ws.Range("B1", "B4");
            r2.SetAutoFilter();

            wb.SaveAs(filterTest);

看图：only one filter in excel file

这里对过滤器有误解！每页一个过滤器是规则，下面的代码会产生所需的结果。

var wb = new XLWorkbook();
            var ws = wb.Worksheets.Add("AutoFilter");
            ws.Cell("A1").Value = "Names";
            ws.Cell("A2").Value = "John";
            ws.Cell("A3").Value = "Hank";
            ws.Cell("A4").Value = "Dagny";


            ws.Cell("B1").Value = "id";
            ws.Cell("B2").Value = "1";
            ws.Cell("B3").Value = "2";
            ws.Cell("B4").Value = "3";
            var r2 = ws.Range("A1", "B4");
            r2.SetAutoFilter();

            wb.SaveAs(filtertest);

result
