当然可以,你可以通过编写VBA(Visual Basic for Applications)宏来实现Excel中合并两个工作表并删除重复数据的功能。这里是一个简单的步骤说明:
1. 打开Excel,按下`Alt + F11`键打开Visual Basic编辑器。
2. 在左侧窗格中选择"插入" -> "模块",然后在右侧空白区域粘贴以下代码:
```vba
Sub MergeAndRemoveDuplicates()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim dataWs As Worksheet ' 新建的工作表用于存放合并后的数据
Dim lastRow1 As Long, lastRow2 As Long
Dim i As Long, j As Long
' 设置需要合并的工作表
Set ws1 = ThisWorkbook.Worksheets("Sheet1") ' 替换为实际的第一个工作表名
Set ws2 = ThisWorkbook.Worksheets("Sheet2") ' 替换为实际的第二个工作表名
' 创建新的工作表并设置起始行
Set dataWs = ThisWorkbook.Sheets.Add(After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count))
lastRow1 = ws1.Cells(ws1.Rows.Count, 1).End(xlUp).Row
lastRow2 = ws2.Cells(ws2.Rows.Count, 1).End(xlUp).Row
' 合并数据并去重
For i = 1 To lastRow1
For j = 1 To lastRow2
If Application.WorksheetFunctiontranspose(ws1.Range(ws1.Cells(i, 1), ws1.Cells(i, ws1.Columns.Count).SpecialCells(xlCellTypeVisible))) _
IsEqual Application.WorksheetFunctionTranspose(ws2.Range(ws2.Cells(j, 1), ws2.Cells(j, ws2.Columns.Count).SpecialCells(xlCellTypeVisible))) Then Exit For ' 判断两列是否相等
Next j
If i > lastRow1 Then ' 如果第一个工作表还没填满,将当前行添加到新工作表
dataWs.Range(dataWs.Cells(lastRow1 + 1, 1), dataWs.Cells(lastRow1 + 1, ws1.Columns.Count)).Value = ws1.Range(ws1.Cells(i, 1), ws1.Cells(i, ws1.Columns.Count))
End If
Next i
End Sub
' 自定义函数,检查两个数组是否相等(忽略大小顺序)
Function IsEqual(ByRef arr1() As Variant, ByRef arr2() As Variant) As Boolean
Dim i As Long, j As Long
ReDim temp(1 To UBound(arr1)) '临时数组用于存储arr1的值
IsEqual = True
For i = LBound(arr1) To UBound(arr1)
For j = LBound(temp) To UBound(temp)
If arr1(i) = temp(j) Then Exit For '找到相同的值就退出循环
Next j
If i >= LBound(arr1) And Not IsNumeric(arr1(i)) Then ' 如果遇到非数值元素,则跳过比较
Continue For
Else
If i < UBound(arr1) Then '如果还没有匹配项,将当前元素存入临时数组
temp(j + 1) = arr1(i)
End If
IsEqual = False '如果所有元素都不匹配,则返回False
End If
Next i
End Function
```
3. 点击`Run`按钮运行宏,它会自动创建一个新的工作表并将两个工作表合并并去除重复的数据。记得替换"Sheet1"和"Sheet2"为你需要合并的实际工作表名称。
