Controlling JQGrid horizontal scroll bar in ASP.NET MVC Application

I have come across a problem with my JQGrids horizontal scroll bar in an ASP.NET MVC application. The issue is, i have given a fixed width to the grid, and expect that horizontal scroll bar should appear dynamically when i resize my columns; but it does not, instead, the grid spills out of the page. I have tried to add a div element with overflow=scroll around the table which holds the grid, even that did not solve the issue.

Am i doing something wrong? I tried to dig through the existing threads, but could not find similar ones.

I have attached the HTML and Script code as a reference. Any help is appreciated.

<div id="div1" class="clsInner">
    <table>
        <tr>
            <td colspan="2" class="clsHeading">
                Existing Proposals
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <table id="list" cellpadding="0" cellspacing="0" class="scroll">
                </table>
                <%-- <div id="pager" class="scroll" style="text-align: center;">
                </div>--%>
            </td>
        </tr>
        <tr>
            <td colspan="2">
            </td>
        </tr>
    </table>
</div>
