主题：以下代码中想加一个小计

参考代码

Dim t As Table = e.Form.Controls("Table1").Table
Dim doc As PrintDoc = e.Form.GernatePrintDoc()
For Each c As object In doc.Body.children
    If typeof c Is prt.RenderTable Then
        Dim i = c.rows.count+1
        c.cells(i, 0).text = "123"
        c.cells(i, 1).text = "abc"
    End If
Next
doc.Preview()
