I have developed a report with SSRS 2012 and when I view the report on the reporting server for some reason the first row of the tablix on page 2 gets hidden under the column header. What could it be??. Also I have enabled to show the column header as and when I scroll down the page but it is not working in here. But this feature is working in the SQL Server Data tool when I test there. I am testing on IE 11. Please help,.
