Numbered rows

Hi there,
I see your online demo shows the first column for the row numbers, but the trial script doesn't show this column. I looked at the docs but I couldn't find the way to add this column...
What am I missing?

It sounds like you want row selectors.

Yes, these two lines made the trick:

obj.setSelectorVisible(true);
obj.setSelectorText(function(i){return this.getRowPosition(i)+1});

Thank you!
