在两张表的两列中查找重复项

Question

我需要比较两个不同工作表中的两列并找出重复项：比较 'Sheet2' 中的 C 列与 'Sheet1' 中的 E 列。作为示例，我只使用了一些但是：

Column E in Sheet1 has 2,000 rows of data.  
Column C in Sheet2 has ~ 100 rows of data.

如何找到 C 列中的重复项，以及如何用 Sheet1 的 E 列涂色 Sheet2 的 C 列的重复项？

Answer 1

似乎不是这个 OP 想要的，但对于具有非常相似要求的其他人来说似乎是一个不错的选择：select Sheet2 中的 ColumnC 和 HOME > Styles - Conditional Formatting, New Rule..., 使用公式确定要设置格式的单元格 和 设置此公式为真的值的格式：：

=COUNTIF(Sheet1!E:E,C1)

格式...,select您选择的格式，好的，好的。

Answer 2

如果你想要 VBA 解决方案，你可以使用这个：

Sub test()

Dim ws1 As Worksheet, ws2 As Worksheet
Dim lR1&, lR2

Dim rng As Range, Frng As Range

Set ws1 = Worksheets("Sheet1") 'Change this to whatever sheet name
Set ws2 = Worksheets("Sheet2") 'Same as above

With ws1

    lR1 = .Cells(.Rows.Count, 3).End(xlUp).Row

End With

With ws2

    lR2 = .Cells(.Rows.Count, 5).End(xlUp).Row

End With

For Each rng In ws1.Range("C1", "C" & lR1) 'Edit this to the range where the values are located you want to find the duplicates of

    Set Frng = ws2.Range("E1", "E" & lR2).Find(what:=rng.Value, LookIn:=xlValues, LookAt:=xlWhole, _
                                        MatchCase:=False, SearchFormat:=False)

    If Not Frng Is Nothing Then

        Frng.Interior.Color = 255

    End If

Next rng

End Sub

但是请注意，这是区分大小写的。
