Chart, Grid and spreadsheet on same page css conflicts

I’m developing a spreadsheet and chart plugin for Moodle. I have a Chart linked with a grid on a page. If I add a spreadsheet to the same page, the spreadheet cells and grid cells are messed up. You can see it at the following link.

It seems to be a css conflict. Any ideas how I can fix this?
