如题，专业报表中，字体的字宽系数能否控制？

Dim ls As WinForm.NumericComboBox = e.Form.Controls("列数")
Dim hs As WinForm.NumericComboBox = e.Form.Controls("行数")
Dim zbj As WinForm.NumericComboBox = e.Form.Controls("字边距")
Dim zt As WinForm.FontPicker = e.Form.Controls("字体")
Dim zg As WinForm.NumericComboBox = e.Form.Controls("字高")
Dim nr As String
For Each r As Row In Tables("表A").Rows
    If r.IsNull("第一列") = False Then
        nr = iif(nr Is Nothing,r("第一列") & r("第二列"),nr & vbcrlf & r("第一列") & r("第二列"))
    End If
Next

Dim doc As New PrintDoc \'定义一个报表
Dim rt As New prt.RenderTable() \'定义一个表格对象
Dim rx As prt.RenderText \'定义一个文本对象
Dim fnt As New Font(Cstr(zt.Value),CInt(zg.Value),FontStyle.Regular)

Doc.PageSetting.PaperKind = 9
Doc.PageSetting.LeftMargin = 2 \'设置左边距
Doc.PageSetting.RightMargin = 2 \'设置右边距
Doc.PageSetting.TopMargin = 2 \'设置上边距
Doc.PageSetting.BottomMargin = 2 \'设置下边距

doc.Body.Children.Add(rt) \'将表格对象加入到报表中
rt.Style.GridLines.All = New prt.LineDef \'将网格线类型设为默认类型
rt.Width = 205 \'表宽为150毫米
rt.Height = 290 \'表高为150毫米
rt.Rows.Count = hs.Value \'设置行数
rt.Cols.Count = ls.Value \'设置列数
For r As Integer = 0 To hs.Value
    For c As Integer = 0 To ls.Value
        rx = New prt.RenderText \'创建一个新的文本对象
        rx.text = nr \'设置文本对象的内容
        rx.Style.Spacing.All = CInt(zbj.Value) \'内容和网格线的距离为1
        rx.Style.Font = fnt \'设置字体
        rt.Cells(r, c).RenderObject = rx \'放置在单元格中
    Next
Next
Doc.Preview() \'预览报表

没有【字宽】这种设置。
