优化提升以下代码速度：Sub 一键检查明细数据() On Error Resume Next Application.ScreenUpdating = False Dim ws As Worksheet Set ws = Worksheets("报表1") Dim lastRow As Long lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row Dim i As Long For i = 2 To lastRow Dim val As Double, judgeVal As String, v2 As Double, v3 As String val = CDbl(ws.Cells(i, 10).Value) judgeVal = CStr(ws.Cells(i, 11).Value) v2 = CDbl(ws.Cells(i, 12).Value) v3 = CStr(ws.Cells(i, 13).Value) If InStr(judgeVal, "-") > 0 Then Dim item() As String item = Split(judgeVal, "-") Dim firstVal As Double, secondVal As Double firstVal = CDbl(item(0)) secondVal = CDbl(item(1)) Dim item2() As String item2 = Split(v3, "-") Dim S1 As Double, S2 As Double S1 = CDbl(item2(0)) S2 = CDbl(item2(1)) If firstVal > val Or val > secondVal Then ws.Cells(i, 10).Font.Color = 255 ws.Cells(i, 9).Font.Color = 255 ws.Cells(i, 9).Value = ws.Cells(i, 10).Value Else ws.Cells(i, 10).Font.ColorIndex = xlAutomatic ws.Cells(i, 9).Font.ColorIndex = xlAutomatic ws.Cells(i, 9).Value = "" End If If S1 > v2 Or v2 > S2 Then ws.Cells(i, 12).Font.Color = 255 Else ws.Cells(i, 12).Font.ColorIndex = xlAutomatic End If If ws.Cells(i, 12).Value = ws.Cells(i, 13).Value Then ws.Cells(i, 12).Font.ColorIndex = xlAutomatic End If End If Next i ActiveWorkbook.RefreshAll Application.ScreenUpdating = True End Sub

使用数组的方式，优化以下代码：Sub 一键检查明细数据() On Error Resume Next Application.ScreenUpdating = False Dim ws As Worksheet Set ws = Worksheets("报表1") Dim lastRow As Long lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row Dim i As Long For i = 2 To lastRow Dim val As Double, judgeVal As String, v2 As Double, v3 As String val = CDbl(ws.Cells(i, 10).Value) judgeVal = CStr(ws.Cells(i, 11).Value) v2 = CDbl(ws.Cells(i, 12).Value) v3 = CStr(ws.Cells(i, 13).Value) If InStr(judgeVal, "-") > 0 Then Dim item() As String item = Split(judgeVal, "-") Dim firstVal As Double, secondVal As Double firstVal = CDbl(item(0)) secondVal = CDbl(item(1)) Dim item2() As String item2 = Split(v3, "-") Dim S1 As Double, S2 As Double S1 = CDbl(item2(0)) S2 = CDbl(item2(1)) If firstVal > val Or val > secondVal Then ws.Cells(i, 10).Font.Color = 255 ws.Cells(i, 9).Font.Color = 255 ws.Cells(i, 9).Value = ws.Cells(i, 10).Value Else ws.Cells(i, 10).Font.ColorIndex = xlAutomatic ws.Cells(i, 9).Font.ColorIndex = xlAutomatic ws.Cells(i, 9).Value = "" End If If S1 > v2 Or v2 > S2 Then ws.Cells(i, 12).Font.Color = 255 Else ws.Cells(i, 12).Font.ColorIndex = xlAutomatic End If If ws.Cells(i, 12).Value = ws.Cells(i, 13).Value Then ws.Cells(i, 12).Font.ColorIndex = xlAutomatic End If End If Next i ActiveWorkbook.RefreshAll Application.ScreenUpdating = True End Sub
