从数组中删除行

我试图遍历一个数组以查找该数组的单列中的重复条目并删除整行。

我正在弄清楚rangeStart, rangeEnd, and lastrow上面这个部分工作正常。

data = Range(rangeStart, rangeEnd)

For i = lastrow - 1 To 2 Step -1
    If data(i - 1, x) = data(i, x) Then
        'Delete data(i)
    End If
Next

任何对此的帮助都会很棒！

Sub RemoveDups()
Const COMPARE_COL as Long = 1
Dim a, aNew(), nr As Long, nc As Long
Dim r As Long, c As Long, rNew As Long
Dim v As String, tmp

    a = Selection.Value
    nr = UBound(a, 1)
    nc = UBound(a, 2)

    ReDim aNew(1 To nr, 1 To nc)
    rNew = 0
    v = Chr(0)

    For r = 1 To nr
        tmp = a(r, COMPARE_COL)
        If tmp <> v Then
            rNew = rNew + 1
            For c = 1 To nc
                aNew(rNew, c) = a(r, c)
            Next c
            v = tmp
        End If
    Next r

    Selection.Value = aNew

End Sub
