I have used these links and got a working code where I can use a template report(containing placeolders) and generate new PPTX report with data I get from database. I have 4 more placeholders where I need to populate 4 different data tables. Currently I am using that template to create new slide and replacing placeholder for text but for tables I couldn't figure out. I am able to generate the table using below code but not in placeholder's location. Table always appear in center of screen.

var newSlidePart = parent.AddNewPart<SlidePart>("newSlide1");
//copy the contents of the template slide to the new slide and attach the appropriate layout
newSlidePart.FeedData(_slideTemplate.GetStream(FileMode.Open));
newSlidePart.AddPart(_slideTemplate.SlideLayoutPart, _slideTemplate.GetIdOfPart(_slideTemplate.SlideLayoutPart));

Okay, I can place the table at any location I want to by changing values in this.. for X and Y.. not sure what Cx and Cy values does. So that works
graphicFrame.Transform = new Transform(new D.Offset() { X = 1650609L, Y = 4343400L }, new D.Extents() { Cx = 6096000L, Cy = 741680L });
But now the new issue is I am unable to reduce the font and table row height. I tried changing this values but nothing works. Will post here when I find out.
D.TableRow tableRow = new D.TableRow() { Height = 370840L };
I had to to make this change in createTextCell method: added FontSize=800
D.RunProperties runProperties = new D.RunProperties() { Language = "en-US", Dirty = false, FontSize=800 };
