使用 openXML 与 c# 和 ASP.net 在 powerpoint 中创建动态表

我已经使用了这些链接并获得了一个工作代码，我可以在其中使用模板报告（包含占位符）并使用从数据库获取的数据生成新的 PPTX 报告。我还有 4 个占位符，需要在其中填充 4 个不同的数据表。目前，我正在使用该模板创建新幻灯片并替换文本的占位符，但对于我无法弄清楚的表格。我可以使用下面的代码生成表格，但不能在占位符的位置生成表格。表格始终出现在屏幕中央。

好的，我可以通过更改 X 和 Y 的值来将表放置在我想要的任何位置。不确定 Cx 和 Cy 值的作用。这样就可以了

graphicFrame.Transform = new Transform(new D.Offset() { X = 1650609L, Y = 4343400L }, new D.Extents() { Cx = 6096000L, Cy = 741680L });

但现在的新问题是我无法减小字体和表格行高。 我尝试更改此值，但没有任何效果。当我发现时会在这里发布。

 D.TableRow tableRow = new D.TableRow() { Height = 370840L };
