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

Put your table in a div block and use CSS to specify the height and overflow property of the div.

  
     ...table content...
  

This way the div has a fixed height and the browser will add a scrollbar when the content of the div block is too height.

I have set the height to 15em, which corresponds with 15 * font-height. When using borders, paddings and stuff this height is incorrect. But it can be calculated more properly (in px) for your design.
