java - Shrink JScroll Pane to same Height as JTable

Question

I currently have JTables nested in JScrollPanes like so:

My problem is that the number of rows in each table is variable when the table is created. What I want to do is make the JScrollpane smaller if the table is too short, but I want to keep it at a set size if the table is too long.

How can I accomplish this?

Answer 1

Dimension d = table.getPreferredSize();
scrollPane.setPreferredSize(
    new Dimension(d.width,table.getRowHeight()*rows+1));

Where rows represents the number of rows of data, or the limit.
