主题：判断当前表的某一行是否空值

For i As Integer = 0 To CurrentTable.Rows.Count - 1

For Each a As Row In CurrentTable.Rows

For Each b As Col In CurrentTable.Cols

If CurrentTable.Cols.Contains("锁定") = True

If a(i).IsNull(b.Name) = false Then

a(i)("锁定") = True

end if

end if

next

next

next

请问上面代码哪里出错了？

或者有其他更便捷的方法？
