Header Date Rows misaligned

[chakin...@gmail.com]

I'm trying to embed the gantt chart into another page with a tampermonkey script.  It reads all of the rows of the source page and builds a gantt out of it on the click of an element.

I've attached a screenshot of the gantt chart with default data in it - It seems like maybe some css is colliding?  Any ideas?

The only things I'm loading it with are jquery.fn.gantt.min.js and the style.css file that came with the package. 

Thanks for your time
