写一个VBA代码实现以下需求1.创建字典，确认表1的F列字符串及个数，2.将字典的字符串返回表2的A列，对应个数返回给B列，3.将字典的字符串有几个就粘贴几个到表3A列

以下是实现上述需求的VBA代码：

Sub Dictionary()

    '创建字典对象
    Dim dict As Object
    Set dict = CreateObject("Scripting.Dictionary")
    
    '获取表1中F列的字符串及个数
    Dim lastRow As Long
    lastRow = Worksheets("表1").Cells(Rows.Count, "F").End(xlUp).Row
    
    Dim str As String
    Dim count As Long
    For i = 2 To lastRow
        str = Worksheets("表1").Range("F" & i).Value
        If dict.Exists(str) Then
            count = dict(str) + 1
            dict(str) = count
        Else
            dict.Add str, 1
        End If
    Next i
    
    '将字典的字符串返回表2的A列，对应个数返回给B列
    Dim j As Long
    j = 2
    For Each key In dict
        Worksheets("表2").Range("A" & j).Value = key
        Worksheets("表2").Range("B" & j).Value = dict(key)
        j = j + 1
    Next key
    
    '将字典的字符串有几个就粘贴几个到表3A列
    j = 2
    For Each key In dict
        For k = 1 To dict(key)
            Worksheets("表3").Range("A" & j).Value = key
            j = j + 1
        Next k
    Next key

End Sub

注意：在使用该代码时，需要将代码中的“表1”、“表2”、“表3”修改成实际的工作表名称。
