办公利器强大的Wlookup匹配公式

Function Wlookup(V, vY, vh, Optional m)

 Dim arr, arr1, arr2()

 Dim k As Integer

 arr = vY

 arr1 = vh

       If UBound(arr1) = 1 Then

       arr1 = Application.Transpose(arr1)

       arr = Application.Transpose(arr)

       End If

ReDim arr2(1 To 1)

 For x = 1 To UBound(arr1)

    If arr(x, 1) = V Then

       Wlookup = arr1(x, 1)

       If IsMissing(m) Then

         Exit Function

       Else

        k = k + 1

        ReDim Preserve arr2(1 To k)

        arr2(k) = arr1(x, 1)

       End If

    End If

  Next x

  If m = 0 Then

    Wlookup = arr2(k)

  ElseIf m = -1 Then

   Wlookup = Join(arr2, ",")

  ElseIf m = -2 Then

   Wlookup = JS(V, vY, vh)

  Else

    Wlookup = arr2(m)

  End If

End Function



Function JS(J1, R1, R2) '取接近值

Dim Jarr1, Jarr2

Dim x

 Jarr1 = R1

 Jarr2 = R2



For x = 1 To UBound(Jarr1)

  If x + 1 > UBound(Jarr1) Then

       JS = Jarr2(x, 1)

       Exit Function

  ElseIf J1 >= Jarr1(x, 1) And J1 < Jarr1(x + 1, 1) Then

       JS = Jarr2(x, 1)

       Exit Function

  End If

Next x

End Function

以上代码是Wlookup在VBA模块，任何EXCEL版本均可以添加该模块开启WLookup公式的使用。具体方法：

Wlookup要想在你的表格中也能使用，需要按下面的步骤操作。

1、按alt+F11（或任一工作表标签右键 - 查看代码）会打开VBE窗口，在窗口中点插入 - 模块。把下面的代码复制粘贴到右侧的空白区域中。
