In IE8, if you view a SQL 2005 SP3 report server report through a Page Viewer web part in SharePoint WSS 3.0, the rendered tables have the right hand borders missing. It only occurs when there is a left/right border-collapse in the table, which suggests a problem with the table width. If you zoom, export or print the report, the borders show. Testing on IE7 reveals borders showing OK for same markup (I compared them). Is this an IE8 bug?
