Set maximum displayed rows count for HTML table

Question

Have JSP page with dynamically generated HTML table with unknown number of rows.

Have property on backend, that sets maximum number of rows, e.g: max_rows=15

Answer 1

There is no way to do this with only CSS and HTML, you need javascript too. Get the height of the top 15 rows, and limit the height of a wrapping div to that height. Set overflow: auto on the div to get your scrollbars.

Don't forget to set a default height on the div as a fallback if javascript is turned off.
