Hi!
The EXCELXP tagset uses Spreadsheet Markup Language to create a file that you can open with Excel. The tagset has an option for freezing headers (on the top) and row headers (on the left). To see whether you have the version of the tagset that create this kind of file, submit a test job with this option:
[pre]
ods tagsets.excelxp file='c:\temp\somefile.xls'
options(doc='help');
proc print data=whatever;
run;
ods tagsets.excelxp close; [/pre]
The documentation for the ExcelXP tagset will be written to the SAS log. What you are looking for in the log is the Frozen_Headers and Frozen_RowHeaders option. If you do not see those options in your SAS log, that means you have to download the newest version of the tagset from the ODS MARKUP web site. I'll put the link below.
If you are not at all interested in an Excel file, then there is a tagset called the HTMLSCROLL tagset that puts some Javascript code into an HTML file to perform frozen_header scrolling inside a web browser. I do not know whether the HTMLSCROLL tagset also allows frozen row header scrolling.
For more information on the HTMLSCROLL tagset or to get an updated copy of the EXCELXP tagset, refer to:

Good luck!
