Table with 7 columns generates an invalid pptx file.

[rikvdk]

var pptx = new PptxGenJS();            
var slide = pptx.addNewSlide();
var rows = [1,2,3,4,5,6,7];

slide.addTable(rows);
pptx.save();

For some reason a table with 7 columns generates a pptx which I cannot open. I tried with 1 to 10 columns and only 7 had this problem.
