How to Make a JTable Look Flat And Modern In Java Netbeans
In this Java Tutorial we will see How To Create a JFrame with a JTable featuring a flat design, custom cell rendering for alternating row colors and selected cell appearance, and a modern look and feel using the FlatLaf library.
The cells in the JTable are set to be uneditable.
What We Are Gonna Use In This Project:
- Java Programming Language.- NetBeans Editor.
- FlatLaf library.
