vba, 同一列里,给单元格找到与其值一样最近的单元格所在行数, 从上往xia的方向

你可以使用以下代码实现：

Function findClosestMatchRow(rng As Range) As Integer
    Dim targetValue As Variant
    Dim minDiff As Double
    Dim currDiff As Double
    Dim matchRow As Integer
    Dim currRow As Integer
    
    targetValue = rng.Value
    minDiff = 99999 ' set a large initial value for minDiff
    
    For currRow = rng.Row - 1 To 1 Step -1 ' search upwards from the current row
        currDiff = Abs(targetValue - Cells(currRow, rng.Column).Value)
        If currDiff < minDiff Then ' found a closer match
            minDiff = currDiff
            matchRow = currRow
        End If
    Next currRow
    
    findClosestMatchRow = matchRow ' return the row number of the closest match
End Function

将这段代码复制到你的 VBA 模块中后，你可以在 Excel 中使用类似于以下公式的方式调用该函数：

=findClosestMatchRow(A1)

其中，A1 是你要查找最近匹配行号的单元格。该函数将返回与该单元格值最接近的单元格所在的行号，从上往下数。
