Resize a Jtable Vertically based on it's content

I have a view in my java project that needs to resize a table. I have n number of Jtables inside a JScrollPane. Some of them doesn't have enough rows to fill the total size of the table. The best solution I think would be to resize the table to fill to the number of rows that were allocated.

1) The table has a dimension of 4x4 but if there is not enough rows (i.e, less than 4) it will have a gap, which I don't want.

Since this table is static and won't be changed how can I resize this table programmatically based on the number of rows that it will have, like having 1, 2 or only 3 rows and not have this gap?

PS: I know how many rows it will have, I just don't know how to resize the table height programmatically during runtime.

After adding all the data to the table you can use:

table.setPreferredScrollableViewportSize(table.getPreferredSize());

Then when the table is added to the scroll pane the size of the scroll pane will be the preferred size of the table.

To make the JTable stretch to fit the height of the view, you can call:

table.setFillsViewportHeight(true);

from the javadoc:

Sets whether or not this table is always made large enough to fill the height of an enclosing viewport.
