Question

I have written a program that reads a csv file and put it into a jTable that will be displayed in a seperate jFrame as a preview. Everything works fine but I would like to use the optimal size for the jTable in the preview frame.

So how to do it? Because if for example I choose another font for the text, the column would be wider or smaller? Is there a method to get the text-length in pixels (size)?`

The class looks like this:

JTable implements Scrollable, and the preferredViewportSize is arbitrarily set to Dimension(450, 400). That size is obtained by wrapping the table in a JScrollPane and invoking pack() on the enclosing Window. Mindful of some important caveats, you can use setPreferredScrollableViewportSize() to change the default size. A multiple of getRowHeight() may be a suitable choice for the height.
