Excel 根据条件修改列

我有以下问题，我有两列，如下所示：

 A B
"X" 1
"Y" 1
"Z" 0
"W" 2

 C D
"X" 1
"Y" 1
"Z" 0
"W (1)" 1
"W (2)" 1

我想做的是找到一种方法来创建新的列C和D，或者更好的是，更新列a和B，如下所示：

 A B
"X" 1
"Y" 1
"Z" 0
"W" 2

 C D
"X" 1
"Y" 1
"Z" 0
"W (1)" 1
"W (2)" 1

如果您有任何建议或想法，我将不胜感激。

这不是一个代码编写论坛。你应该表现出一些努力

Sub split_()

Dim P1 As Range
Range("C1:D99999").Clear
Set P1 = Range("A1").CurrentRegion
a = 1

For i = P1(1).Row To P1.Rows.Count
    If P1(i, 2) > 1 Then
        For j = 1 To P1(i, 2)
            Cells(a, 3) = P1(i, 1) & " (" & j & ")"
            Cells(a, 4) = 1
            a = a + 1
        Next j
    Else
        Cells(a, 3) = P1(i, 1)
        Cells(a, 4) = P1(i, 2)
        a = a + 1
    End If
Next i

End Sub
