老师以上代码我想在表格最后加一行合计出库存件数要怎么加代码？

        rT.Style.Spacing.Bottom = 0 '和下面的对象(表格)距离3毫米
       rt.Cells(rt.rows.count, 0).Text = tb.compute("sum(库存件数)")
        doc.Body.Children.Add(rt)

 rt.Cells(rt.rows.count, 0).Text = "合计"
        rt.Cells(rt.rows.count, 5).Text = tb.compute("sum(出库件数)")
        rt.Cells(rt.rows.count, 6).Text = "件"
我这样加老是显示成三行？我想它显示在同一行上就行的。

dim k as integer = rt.rows.count
