PNG only exports viewable portion of table

[schutze]

The PNG option only exports the portion of the table that is currently viewable in the browser window. If you lower the browser magnification, more rows of the table are included in the exported PNG.
The PNG option should export the entire HTML table and not just the rows that are currently shown.

This plugin uses html2canvas to export a html table as png image. The result image is a screenshot of the table as you can see it on the screen.

Which is a weired behavior, indeed.
Here is a discussion related to this "feature" : niklasvh/html2canvas#622 (comment)

For my part, I added a piece of js to export my whole table. You should just scroll to top before exporting to PNG. Not very user friendly but at least, it works.
