如果下面行中的值非空，则连接列标题 [英] Concatenate column headers if value in rows below is non-blank

问题描述

我有以下格式的数据表.

I have table with data in the format below.

我希望完成的表格中的空白列像下面突出显示的那样填充.

I want the finished table to have the blank column to be populated like the highlighted one below.

所以，我需要一个公式或 VBA 来返回并连接每一行中非空白单元格的标题.

So, I need a formula or VBA that will return and concatenate the headers of non-blank cells in each row.

推荐答案

使用¹以下作为数组公式.

=TEXTJOIN("-->", TRUE, IF(LEN(C3:I3), C$2:I$2, ""))

Pre-Excel 2016 版本

虽然您可以将一系列 IF 语句串在一起，但更简洁的替代方法可能是编写用户定义的函数(又名 UDF).

While you could just string together a series of IF statements, a cleaner alternate might be to write a user defined function (aka UDF).

在标准 VBA 模块代码表中:

In a standard VBA module code sheet:

Function udf_Stitch_Together(r As Range, _
                             h As Range, _
                             Optional d As String = "-->", _
                             Optional blnks As Boolean = False) As String
    Dim s As String, c As Long
    For c = 1 To r.Cells.Count
        If CBool(Len(r.Cells(c).Text)) Then _
            s = s & IIf(Len(s), d, vbNullString) & h.Cells(c).Text
    Next c
    udf_Stitch_Together = s
End Function
