It might be then that only a certain number of rows loads at a time and further rows only load when you scroll down. Some web pages are like that. Unfortunately, if the rows do not load, PAD cannot extract them. You will likely need to make your flow scroll in a loop to extract further rows into separate tables.
Alternatively, you might want to investigate if the page has an API you could use to extract the data. Or an alternative way to get the data, like exporting it to a file or something.
