I need to create a SSRS report like
And I have table with 3 columns DeveloperName,TimeWorked, Date
How can I create the rep
You can use Matrix (instead of tab-lix) to generate dynamic columns. There is no changes required in your sql query for matrix report (its just a list of DeveloperName,TimeWorked, Date) , but the Matrix control in the SSRS will handle all this. You can refer the below inks http://ssrstutorials.blogspot.in/2012/10/lesson-15-ssrs-matrix-reports.html or https://msdn.microsoft.com/en-us/library/dd207149.aspx
