Wrapping Text lines in JqGrid

Try the following CSS:

    .ui-jqgrid tr.jqgrow td {
        white-space: normal !important;
    }

This works for me using jqGrid 3.6.

As N30 pointed out, jqGrid 4.0 now supports a cellattr colModel option which can allow for a finer grain of control over text wrapping. From his example:

cellattr: function (rowId, tv, rawObject, cm, rdata) { 
    return 'style="white-space: normal;"';
}
