Datatable table width increases in google chrome but remains correct in IE

I am using datatable in one of our application and applied properties as "bAutoWidth": false and hardcoded the width of table columns using swidth property. This keeps my table width constant in IE but the same cant be said about Chrome. Even after hardcoding the width of columns and setting "bAutoWidth": false, the table width increases in GOOGLE CHROME. Can anyone help me with this issue? Thanks.
