I'm trying to automate the creation of a powerpoint presentation using mlreportgen.ppt. I have two rows of headers, the first row is a overarching header, while the second is the detailed header. This results in cells that need to be merged (as I would do it in PPT) or nested arrays (like I would use in LaTeX or HTML). Is there anyway to do this currently? My thought was to create a Table object and try to append an empty TableEntry with the table, but its a no go.
