Not able to do page down in table control of screen

Question

Hello,
I have created a table control on a screen of my report. This screen gets called from my selection screen. When I do page down or click on down arrow key to view other table entries nothing is happening. The scroll bar is not moving vertically.
Someone told me that no coding is required to make the table scrollable vertically.
Can someone please tell me if there is any attribute that needs to be set for this?
Best Regards,
