Is there any alternative to JTable, that is free and better?

Question

Looking for a free and better alternative to JTable. Found quite a few good ones, but they aren't free.

To begin with, I want to be able to select cells diagonally (apart from horizontally and vertically).

Answer 1

JXTable (from SwingLabs) has several nice features (Column Control, Toggle Column Visibility, Highlighting Rows, Sorting Rows, Filtering Rows, Horizontal Scroll Control, and Resizing Columns), and it is free.

But it's hard to say definitely that you'll like it when you don't say what features you're looking for.
