loObject=window.parent.document.getElementById("TD2") loObject.style.width=tnWidth-lnWidth alert(loObject.width) alert(loObject.style.width)The first alert message will show the width of the cell as defined in the HTML page. The second alert message will show the actual width of the cell as redefined on the second line. Why is the first message not able to show the actual width of the cell but always the original width as defined in the HTML?
