[xwiki-users] Formatting tables into viewport with sliders

Hi, I've got a few wiki pages that contain large tables (more columns than will fit across the page and more rows than will fit down the page), after being imported from a spreadsheet. I'd like to restrict the view of such tables to what can be shown in the visible area, with sliders to move around. Is there already a facility to do this, or a simple styling parameter? Thanks, Bryn
