Question

您好，我需要根据行是 null 还是具有任何值来连接列。
即我有这样的数据

我需要这样的数据

问题是我要加入的列将超过 50 列，对于每列我必须检查该列和行中是否有空白或数字。

你能帮我解决这个问题吗？

如果您要求 VBA 解决方案，请尝试下一个代码。 它将处理尽可能多的Value列，并在最后一列之后返回两列的处理结果。 使用 arrays，即使对于大范围，代码也会非常快：

Sub ConcatenateWithValues()
   Dim sh As Worksheet, lastR As Long, lastCol As Long, arr, arrH, arrFin
   Dim strConc As String, i As Long, j As Long
   
   Set sh = ActiveSheet   'use here the sheet you need
   lastR = sh.Range("A" & sh.Rows.count).End(xlUp).row          'last row on column A:A
   lastCol = sh.cells(1, sh.Columns.count).End(xlToLeft).Column 'last column on the first row
   
   arr = sh.Range("A1", sh.cells(lastR, lastCol)).Value         'place the whole range in an array, for faster iteration
   arrH = sh.Range("A1", sh.cells(1, lastCol)).Value            'Place headers in an array
   ReDim arrFin(1 To UBound(arr), 1 To 2)                       'Redim the array to contain the processing result
   arrFin(1, 1) = arrH(1, 1): arrFin(1, 2) = "Concatenate_Value"'Place the headers in the array
   For i = 2 To UBound(arr)
        For j = 2 To lastCol 'build the necessary concatenation
            If arr(i, j) <> "" Then strConc = strConc & arrH(1, j) & ":" & arr(i, j) & ";"
        Next
        arrFin(i, 1) = arr(i, 1): arrFin(i, 2) = left(strConc, Len(strConc) - 1) 'remove the last ";" character
        strConc = ""         'reinitialize the string keeping row concatenation
   Next i
   'Drop the processed array content at once:
   sh.cells(1, lastCol + 2).Resize(UBound(arrFin), 2).Value = arrFin
End Sub

使用Microsoft-365 ，您可以尝试 -

=TEXTJOIN("; ",TRUE,FILTER(IF($B$2:$D$5<>"",$B$1:$D$1&":"&$B$2:$D$5,""),$A$2:$A$5=F2))
