Line break in Grid

Hallo,

i inserted the string with the break line into the cell of grid table according to the example

http://ui.agiletoolkit.org/demos/grid.php.

But I can not get the line break with the following statement

<div>1</div><div>1</div> 2<br />2<br />

The html code was only be displayed as string. Does anyone have any idea

BR
