Load a summary table in webpage using API_GenResultsTable without pagination

I have a summary report with 300 rows. I am loading it in a webpage using API_GenResultsTable. But it is showing only 100 rows on webpage. My requirement is to load 300 rows on UI. I have also tried options as num-300. But it didn't work. Is there any way to load all the records in UI or to remove pagination from the loaded report?
Thanks in Advance.
