Datagrid column data is not wrapping up in Firefox and IE11

I have a custom data grid. Here column data is not breaking up when it exceeds fixed width of the column. The data is wrapping up until IE8 but not in IE11 and Firefox.

I tried <ItemStyle Wrpa=true>

and also
when I tried below, style element is not contain work-break showing in html page.

<div style="word-break break-all">
