Providing an example to demonstrate your issue may be more appropriate.

my demo file put the attach, the most important line of code is _{<script type="text/javascript" src="../../jquery.easyui.min.js"></script>}, which means the "jquery.easyui.min.js" file come from local, and it's version is 1.3.2. the error is a select tab action will change all columns' width. but changing the line to _{<script type="text/javascript" src="http://www.jeasyui.com/easyui/jquery.easyui.min.js"></script>} , which means  the "jquery.easyui.min.js" file come from www.jeasyui.com, the demo run excellent.
http://www.jeasyui.com/easyui/jquery.easyui.min.js version is also 1.3.2, whether change than the released version 1.3.2？
