Changing the width of SharePoint list column

Changing the width of SharePoint list column is something that is not available out of the box. The solution is to add a javascript snippet in a content editor web part on the list view page.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script>

<script type="text/javascript">
                $(document).ready(function(){

$('.ms-vh2-nograd:contains("Related Models")').css("width", "300px");

$('.ms-vh2-nograd:contains("Data Source IQDs")').css("width", "300px");


                });
</script>
