There’s a method in JComponent called scrollRectToVisible() which interacts with the parent scroll pane (if one exists) to change its viewport. It takes a Rectangle as an argument that specifies the area you want to be visible in the viewport.
So for example to scroll to a given row in a JTable you would use something like this:
0, row * table.getRowHeight(),
If you have a CSV (or TSV) that you need to display in a JTable then you should have a look at the TableModelExtTextLoader class from SwingLabs.
It provides all you should need and save you the hassle of reinventing the wheel and using a half baked CSV implementation.
Here is an example of it’s usage.
URL csv = new URL("http://myapp/employees.csv");
DefaultTableModelExt data = new DefaultTableModelExt(url);
TableModelExtTextLoader loader =
new TableModelExtTextLoader(",", false, 75);
As many of you will probably have a file from disk that you want to load then see “How to convert a File to a URL”
