EPPlus自动过滤器仅适用于最后一个单元

Question

我希望标题中的每个单元格都包含一个自动过滤器.下面是我试图使用的代码,但是autofilter只在指定的最后一个单元格上设置了.

例如,如果我注释掉该autofilter命令K1,则将创建电子表格,该电子表格是C1唯一具有自动过滤器的单元格.

        //Headers
        ws.Cells["A1"].Value = "ChannelCode";
        ws.Cells["A1"].AutoFilter = true;
        ws.Cells["B1"].Value = "DrmTerrDesc";
        ws.Cells["B1"].AutoFilter = true;
        ws.Cells["C1"].Value = "IndDistrnId";
        ws.Cells["C1"].AutoFilter = true;
        ws.Cells["D1"].Value = "StateCode";
        ws.Cells["D1"].AutoFilter = true;
        ws.Cells["E1"].Value = "ZipCode";
        ws.Cells["E1"].AutoFilter = true;
        ws.Cells["F1"].Value = "EndDate";
        ws.Cells["F1"].AutoFilter = true;
        ws.Cells["G1"].Value = "EffectiveDate";
        ws.Cells["G1"].AutoFilter = true;
        ws.Cells["H1"].Value = "LastUpdateId";
        ws.Cells["H1"].AutoFilter = true;
        ws.Cells["I1"].Value = "ErrorCodes";
        ws.Cells["I1"].AutoFilter = true;
        ws.Cells["J1"].Value = "Status";
        ws.Cells["J1"].AutoFilter = true;
        ws.Cells["K1"].Value = "Id";
        ws.Cells["K1"].AutoFilter = true;

Answer 1

EPPlus .AutoFilter是一个小小的车...我建议使用这样的范围:

ws.Cells["A1:K1"].AutoFilter = true;

Answer 2

适用于所有表单数据范围

worksheet.Cells[worksheet.Dimension.Address].AutoFilter=true;

Answer 3

如果您具有一组动态列，或者它们在数组或列表中定义：

string[] columns = new string[] { "Name", "City", "Street" };

worksheet.Cells[1, 1, 1, columns.Length].AutoFilter = true;

使用的重载如下：

public ExcelRange this[int FromRow, int FromCol, int ToRow, int ToCol] { get; }

我个人更喜欢此方法，而不是将整数（columns.Length）转换为带有字符的Excel范围（例如“ A1：C1”）。
