How to change the width of Queue Title column?

QueueItem and its Views are not customizable in CRM v3.0, one requirement was make the Title column wider then users can see more information. (The Title column contains subject of activities/cases)
By default, Title column width = 300px, so how to change it to 500px? Here's my soluiton:

/*
../workplace/home_workplace.aspx
Make the queue title column width = 500px
*/

//1. Edit CRMWeb/workplace/home_workplace.aspx, add a new JavaScript function call: titleWidth()
function titleWidth()
{
    var barCols = document.getElementById("crmGrid_gridBarCols");
    barCols.getElementsByTagName("COL")[2].width = 500;
    crmGrid.Refresh();
}

//2. Call this function from the existing nodeSelect() and window.onload(). 
function nodeSelect( sQueueId, sViewId, sMenuId )
{
    ......
    titleWidth();
}

function window.onload()
{
    ......
    titleWidth();
}
