How to show horizontal scroll bar in jqgrid

Question

I have a wide jqgrid that I have narrowed by mean of the width property. When I used that, no horizontal scroll bar appears. How can I show it?

Any help will be greatly appreciated,

Thanks

Jaime

EDIT:

This is the current JS code I have. Scrollbar is still not shown:

<script type="text/javascript">
$(function () {
    $("#personal").jqGrid({

Without any code, some things you'll need to look at...

Do not use autowidth and make sure you are not using shrinkToFit (it needs to be set to false). Other than that, the horizontal scrollbar should appear with just those two changes. In addition to this, you should also make sure you set the width explicitly for each column within the column model.
