How can I programmatically add tables in PowerPoint?

I have several tables that I want to insert in PPT programatically. The tables are splits in chunks. and I store the tables in .mat format. Now I want to insert them into slides in a loop. How can I do this? As I didn't find anything in the mlreportgen.ppt document.

import mlreportgen.ppt.*
ppt = Presentation('myfile');
open(ppt);

dt = dir('*.mat');
for i = 1:length(dt)
    TableSlide = add(ppt,'Blank');
    img = mlreportgen.ppt.Table(sprintf('subTable%d',i))
    add(TableSlide,img);
end
close (ppt)
