IE displaying some widgets incorrectly in GWT

I have a strange issue in my GWT app. My application is working fine and looking good in Google Chrome and Firefox. But in IE, I am facing some issues in visual display of widgets. The issues are:

• ListGrid is having some extra spaces (with dark black spaces) between each column and misalignments of entire grid.
• In ListGrid I have implemented a functionality to do some task开发者_如何学编程 when clicking a particular cell in it. That is working good in FF/Chrome but not in IE.
• Each column is misaligned in ListGrid. For example, the column corresponding to row header 3 is aligned to row header 2.

Please help me in solving these issues.

Did you set "user.agent" property in your *.gwt.xml file to include IE?

Actually upgrading the SmartGWT library to latest version fixed these issue. As i tested these issues earlier using firebug and IE developer tools, it seems the problem with CSS handled for various widgets in SmartGWT.
Thanks every1 for your help
