Dim doc As New PrintDoc '定义一个报表

For i As Integer = 1 To Tables("表名").Current("份数")

    rt.Style.Spacing.All = 2 '和其他对象之间的间隔为2mm
    rt.SplitVertBehavior = prt.SplitBehaviorEnum.Never '避免垂直换页的时候,表格被分割成两部分.
    rt.Cols(0).Width = 15
    rt.cells(0,0).Text = "产品编号"
    rt.cells(0,1).text = "YR-35"

    rt.Rows(7).Style.BackColor = Color.LightGray
    doc.Body.Children.Add(rt) '将表格对象加入到报表中
Next
Doc.Preview() '预览报表
