Please can you provide code samples showing how to do Page breaks in tables and also how to force page breaks in slide before getting to the end of a slide.
I have observed your requirements and like to share that I am unable to find any Page break option even in PowerPoint. The requested support is unavailable in Aspose.Slides too. If by page break you mean that you add some table in slide and when it reaches end of slide, the table may be moved or duplicated on next slide for remaining portion then in that case you need to develop your own logic to check the table height whenever you add some data in table and check if the table height + table Y position is not exceeding slide height. If the condition comes out to be true then you add a new slide with similar table or even clone the existing slide and populate the tables data with new data.
Please share, if I may help you further in this regard.
