Buttons - how do they work?

[winkler1]

On http://carlosvillu.github.io/react-spreadsheet/#, the two arrows and the (i) don't seem to be implemented. Should not be there maybe? CSV export works fine.

The two arrows should add new columns and rows. In my browser are working. And (i) should be removed becaue dont make sense with the Readme in the repo.

oh...does it at the end. Totally unexpected. Tooltip on buttons would be good, IMO makes sense to insert after current selection.

Make sense insert after the current selection. But after I am thinking in implement the headers to select a column o row.

I will put tooltip in each button to explain better the behaviour
