这段代码是什么意思rowNew = 2 shtResult.Range("A2:B" & Rows.Count).Clear

这段代码的作用是将变量 `rowNew` 的值设置为 2，然后清除工作表 `shtResult` 中从 A2 到 B 最后一行的数据。

`rowNew = 2` 将变量 `rowNew` 的值设置为 2，这个变量用于在结果表中确定下一个可写入数据的行号。

`shtResult.Range("A2:B" & Rows.Count).Clear` 是一个清除操作，它会清除工作表 `shtResult` 中从 A2 到 B 列最后一行的数据。通过使用 `Rows.Count` 可动态地获取最后一行的行号，确保清除范围是从 A2 到最后一行。

这段代码是什么意思Sub 比较两表数据() Dim sht1 As Worksheet Dim sht2 As Worksheet Dim shtResult As Worksheet Dim Rng As Range Dim row1 As Long Dim rowNew As Long Dim sNo As String Dim QTY As Double Set sht1 = Sheets("sheet1") Set sht2 = Sheets("sheet2") Set shtResult = Sheets("sheet3") rowNew = 2 shtResult.Range("A2:B" & Rows.Count).Clear For row1 = 2 To sht1.Range("A1").CurrentRegion.Rows.Count sNo = sht1.Cells(row1, 1).Value QTY = sht1.Cells(row1, 5).Value Set Rng = sht2.Range("A:A").Find(sNo, lookat:=xlWhole) If Rng Is Nothing Then shtResult.Cells(rowNew, 1).Value = "'" & sNo shtResult.Cells(rowNew, 2).Value = "数据表2中不存在" rowNew = rowNew + 1 Else If QTY <> Rng.Offset(0, 4).Value Then shtResult.Cells(rowNew, 1).Value = "'" & sNo shtResult.Cells(rowNew, 2).Value = "两表的数量不相同" rowNew = rowNew + 1 End If End If Next row1 For row1 = 2 To sht2.Range("A1").CurrentRegion.Rows.Count sNo = sht2.Cells(row1, 1).Value QTY = sht2.Cells(row1, 5).Value Set Rng = sht2.Range("A:A").Find(sNo, lookat:=xlWhole) If Rng Is Nothing Then shtResult.Cells(rowNew, 1).Value = "'" & sNo shtResult.Cells(rowNew, 2).Value = "数据表2中不存在" rowNew = rowNew + 1 End If Next row1 End Sub

这段代码是一个 VBA 宏，用于比较两个数据表中的数据。代码中定义了几个变量和工作表对象，然后通过循环遍历数据表中的行。在循环中，代码会从第一个数据表中获取一行的特定单元格值，并通过 `Find` 方法在第二个数据表中查找是否存在相同的值。如果不存在，则将该值和相应的提示信息写入结果表。如果存在，则比较两个表中的数量是否相同，如果不相同则将该值和相应的提示信息写入结果表。

代码的最后一部分是对第二个数据表进行遍历，如果第二个表中存在第一个表中没有的数据，则将这些数据和相应的提示信息写入结果表。

通过执行这段代码，可以比较两个数据表中的数据，并将不一致或缺失的数据记录到结果表中。
