I am currently doing web UI automation using Robot Framework. For my current task I have a div tag which shows a table inside. The table only shows 25 elements at load time. See image of elements for reference.

After scrolling the top div tag slowly, it creates new set of tables. See below image:

The point is it doesn't show all tables at one go. Also it keeps on adding tables with _startrow attribute to a random value. It also deletes tables from earlier rows on scrolling.
I am not sure how to deal with such dynamic content. Using Execute Javascript keyword has not helped as well.
Any new help would be appreciated. Thank you.
