Tested this PR locally on FF, Safari, Chrome, and Edge25 works well.
The only concern over here is which one should we be removing the "legacy
method" or the one that is avail with the data-grid table. I mean the "legacy
method" is always shown even when the visualization is selected, and the
download button on data-grid get hidden as soon as visualization.
If we all agree to this then LGTM.---
