VBA匹配并更新现有并将新字段添加到下一行的下一个空单元格中

Question

我是新来的，我正在尝试做一个 VBA Vlookup 功能。

我的目标是使用 A 列 VLookup Table1 从 Sheet 1 到 Sheet2 从 Sheet2 并更新列 B 和 C 如果 A 存在。

如果 A 不存在，则添加到 Table1 中的下一个空白行，其中 B 列和 C 列也包括在内。

请参考下图 - Sheet1 的预期更新结果。

提前谢谢你。

目前只能编写代码以更新现有字段，但不确定如何将不匹配的字段添加到 Sheet1 的下一个空白行中。

Sub getOpenExcel()

    '   Your daily report has a date in it's name
    '   to select an open workbook we must first know it's name
    '   AND - it must be already open
    '   Your examples are 2017-03-11-18875, 2017-03-12-18875, 2017-03-13-18875

    '   If the name is the current date then this would work to get the filename

    Dim fileName As String, monthNum As String, dayNum As String, wb1 As Workbook, wb2 As Workbook
    Dim ws1 As Worksheet, ws2 As Worksheet, rng1 As Range, rng2 As Range

    '   this adds a ZERO to the front of month numbers less than 10
    If Month(Date) < 10 Then
        monthNum = "0" & CStr(Month(Date))
    Else
        monthNum = CStr(Month(Date))
    End If


    '   You may or may not need this section
    '   it adds a ZERO to the front of day numbers less than 10
    If Day(Date) < 10 Then
        dayNum = "0" & CStr(Day(Date))
    Else
        dayNum = CStr(Day(Date))
    End If
    '   many cases the daily report will come from the previous day
    '   If your file has yesterday's date, then comment out the above code and
    'uncomment the following code
    '
    'If Day(DateAdd("d", -1, Date)) < 10 Then
    '    dayNum = "0" & Day(DateAdd("d", -1, Date))
    'Else

    fileName = "GREENBILL_RECON_DETAILED_REPORT_" & CStr(Year(Date)) & monthNum & dayNum
    '   if today's date is 3/14/17 then "fileNem" = "2017-03-12-18875"

    '   If your daily report is an excel book, then we need to add the proper extension.
    '   It could be one of many, "xls", ".xlsx" , ".xlsm", etc....
    '   If your daily report is open - look at the top.  It should have the file name and extension.'
    '   Replace the below extension with the correct one.

下面的代码通过匹配两张表的 A 列来遍历所有行。如果没有找到，这将在 sheet1 中添加一个新行。

Dim lngRow1, lngRow2 As Long
lngRow1 = Sheets("Sheet1").Cells(Rows.Count, 1).End(xlUp).Row
lngRow2 = Sheets("Sheet2").Cells(Rows.Count, 1).End(xlUp).Row

Dim isFound As Boolean
Dim lastRow As Long
Dim i, j As Long

lastRow = lngRow1
For i = 1 To lngRow2
    isFound = False
    For j = 1 To lngRow1
        If Sheets("Sheet1").Range("A" & i) = Sheets("Sheet2").Range("A" & j) Then
            Sheets("Sheet1").Range("B" & i) = Sheets("Sheet2").Range("B" & j)
            Sheets("Sheet1").Range("C" & i) = Sheets("Sheet2").Range("C" & j)
            isFound = True
        End If
    Next j
    If Not isFound Then
        lastRow = lastRow + 1
        Sheets("Sheet1").Range("A" & lastRow) = Sheets("Sheet2").Range("A" & i)
        Sheets("Sheet1").Range("B" & lastRow) = Sheets("Sheet2").Range("B" & i)
        Sheets("Sheet1").Range("C" & lastRow) = Sheets("Sheet2").Range("C" & i)
    End If
Next i

考虑上述示例图像编写的代码。如果列数与示例不同，请相应地修改代码。
