Adding COL to a table using DOM

Copy linkTweet thisAlerts:
May 30.2003

Hi,

Has anybody successfully added a COL to an HTML table using the DOM and appendChild? I am currently setting the width of a column by setting the width of each cell. I want to set the width on just the column. Although the code doesn’t error it doesn’t have any effect. However, if I debug and get the innerHTML and paste it into a new HTML document the effect of my width change is apparent.

The snippet of code I’m using is:

var oCol = document.createElement(“COL”);
oCol.width = 100;
oTableBody1.appendChild(oCol);

Any ideas?

Many thanks,
Marek Walford

oCol.style.width = 100;

oCol.style.width = "100px";

oCol.setAttribute("width", 100);

oCol.width = 100;

It's something to do with the DOM becuase I can get the innerHTML and documnet.write it and it's fine!

Success!
