Header text in Title Subtitle format

I need to get the header text in datatable in Title and subtitle format where a single header will have text as “Header 1” and below that its subtitle “This is header 1” something like this sort within single header. Is it possible to do something like this. Any snippet demonstrating above will be very helpful. Thanks in advance.

Basically I need two header text within single header so that I can have second header in next line always.
