How doI put Captions/laberls in my grid for each column?

I need multiline labels:

0-information 1

2- information 2

3- information 3

I tried

value ';

but it doesn’t work.

The grid uses native tooltips ( the title attributed maped to title attribute of result html tag ) - so they works exactly the same as titles in normal HTML.
The next will work in case of IE


Can I make it work in Mozilla Firefox?

As far as I know - Firefox always show title as single line of text.
