Split data in one worksheet to multiple worksheets based on column in Excel using vba

Question

I am trying to split data in sheet 1 to multiple sheets based on the name column in cell A3 onwards. The problem that I am facing is I'm unable to track down the data if there are gap in between. Example the name starts from A3 to A100 and in between cell A10, A20 & A30 is empty the program will only track down value from A3 to A9. The other problem for me is to specify the header. The header that I want to use start from cell A2, B2, C2 & D2 and this program show the header as A1, B1, C1 & D1 as there are value in that cell. This is my code.

Private Sub CommandButton1_Click()

Dim ws As Worksheet, Rng As Range, cc
Dim temp As Worksheet, CostC As Range, u

Set ws = Sheets("Sheet1") 'where your original data. adjust to suit
Set Rng = ws.Range("a1").CurrentRegion.Resize(, 15)
Set CostC = ws.Range("a3", ws.Range("a" & Rows.Count).End(xlUp))

u = UNIQUE(CostC)
Application.ScreenUpdating = 0
For Each cc In u
    With Rng
        .AutoFilter field:=1, Criteria1:="=" & cc
        On Error Resume Next
        Set temp = Sheets(cc)
        On Error GoTo 0
        If Not temp Is Nothing Then

DoThis:

        .SpecialCells(xlCellTypeVisible).Copy temp.Range("A1")
        Else
            Set temp = Sheets.Add
            temp.Name = cc
            GoTo DoThis
        End If
        .AutoFilter
    End With
    Set temp = Nothing
Next
Application.ScreenUpdating = 1

End Sub

Function UNIQUE(r As Range)
Dim a, v
If IsArray(r.Value) Then
    a = r.Value
    With CreateObject("scripting.dictionary")
        .comparemode = vbTextCompare
        For Each v In a
            If Not IsEmpty(v) Then
                If Not .exists(v) Then .Add v, Nothing
            End If
        Next
        If .Count > 0 Then UNIQUE = .keys
    End With
    Erase a
Else
    UNIQUE = r.Value
End If

End Function

Here's a slightly less-optimized but simpler to follow version:

Private Sub CommandButton1_Click()

Dim ws As Worksheet,  c As Range
Dim temp As Worksheet, CostC As Range, u

Set ws = Sheets("Sheet1") 

Set CostC = ws.Range(ws.Range("A3"), ws.Range("A" & Rows.Count).End(xlUp))

For each c in CostC.Cells

    u = trim(c.Value)
    If len(u) > 0 then

        Set temp = Nothing '<<EDIT
        On Error Resume Next
        Set temp = Sheets(u)
        On Error GoTo 0

        If temp is Nothing then
            Set temp = Sheets.Add()
            ws.Range("A2").Resize(1, 15).Copy temp.range("a1") 'copy headers
            temp.Name = u
        End If

        c.resize(1, 15).copy temp.cells(rows.count,1).end(xlup).offset(1,0)

     End if 'have name

Next c
End Sub

使用ColumnDifferences方法返回一个范围，然后使用该范围的Areas(1)属性将数据复制到新的工作表中，然后可以删除数据并重复或遍历这些区域并复制它们。
