请帮忙解释下面语句意思-2
'填写遗漏值
Dim n As Integer
Dim arrR() As Integer, arrB() As Integer
ReDim arrR(5), arrB(5)
Dim r As Range
Dim k As Long
Dim t As Integer
arrR(0) = 9
arrB(0) = 9
Range("B3:AX7").Value = ""

For n = 2 To 50
k = 9

Do While Cells(k, n).Text = ""
k = k + 1
Loop

For t = 1 To 5
Do While Cells(k, n).Text = ""
k = k + 1
Loop
arrR(t) = k
arrB(t) = k
k = k + 1
If n < 35 Then
If Cells(k, n).End(xlDown).Row > 65530 Then Exit For
Cells(t + 2, n) = arrR(t) - arrR(t - 1) - 1
ElseIf n > 34 Then
If Cells(k, n).End(xlDown).Cells.Row > 65530 Then Exit For
Cells(t + 2, n) = arrB(t) - arrB(t - 1) - 1
End If
Next t
Next n
Exit Sub
End If ' If Target.Value = Sheets("双色球").Cells(i, 2)
Next i
Else 'If Len(Target.Value) = 7
Exit Sub
End If 'If Len(Target.Value) = 7

End Sub

答案

Do While Cells(k,n).Text = ""
循环执行 条件是 如果表格 行K 列N 的内容是“”（空的） 就继续循环执行
